Chapter 1. Product Overview

1.1 INTRODUCTION

This chapter provides an overview of the ATA6560/1/2/3/4/6 Evaluation Kit and covers the following topics:

• ATA6560/1/2/3/4/6 Short Overview
• What is the ATA6560/1/2/3/4/6 Evaluation Kit?

1.2 ATA6560/1/2/3/4/6 SHORT OVERVIEW

The ATA6560/1/2/3/4/6 is a high-speed CAN transceiver family that provides an interface between a controller area network (CAN) protocol controller and the physical two-wire CAN bus. The transceiver is designed for high-speed (up to 5 Mbit/s) automotive CAN applications delivering differential transmit and receive capability to (a microcontroller with) a CAN protocol controller. It offers superior electromagnetic compatibility (EMC) and electrostatic discharge (ESD) performance, as well as features such as:

• Ideal passive behavior to the CAN bus when the supply voltage is off
• Direct interfacing to microcontrollers with supply voltages from 3V to 5V (ATA6561, ATA6563, ATA6564, ATA6566)

Three operating modes together with dedicated fail-safe features make the ATA6560/1/2/3/4/6 an excellent choice for all types of high-speed CAN networks, especially in nodes requiring low-power mode with wake-up capability via the CAN bus.

The ATA6560/1/2/3/4/6 CAN transceivers are very similar, they mainly differ in the function of pin 5 and pin 8 as depicted in the following table:

Connecting an external 5V DC power supply between the terminals VCC and GND puts the IC in one of the three operating modes: Normal, Silent (with ATA6560, ATA6562 and ATA6564 only) and Standby, which can be selected via the STBY and NSIL pins (see Section 3.8 "System Control Pins (STBY, NSIL, S)"). See Table 2-1 for a description of the operating modes under normal supply conditions.

FIGURE 2-1: Switch Jumpers for Changing the Operating Mode (J2 Available for ATA6560 and ATA6562 only).

2.4 NORMAL MODE

A low level on the STBY pin together with a high level on pins TXD and NSIL (ATA6560 and ATA6562) or a low level on the S pin (ATA6564) selects the Normal mode. In this mode, the transceiver is able to transmit and receive data via the CANH and CANL bus lines. The output driver stage is active and drives data from the TXD input to the CAN bus. The high-speed comparator (HSC) converts the analog data on the bus lines into digital data which is output to the RXD pin. The bus biasing is set to VCC/2 and the undervoltage monitoring of VCC is active.

The slope of the output signals on the bus lines is controlled and optimized in a way that guarantees the lowest possible electromagnetic emission (EME).

To switch the device in normal operating mode, set the STBY pin to low (switch jumper J1 set to the right side) and the NSIL pin (if available) to high (switch jumper J2 set to upper position). For example, for test purposes a signal generator can also be connected to the STBY pin and/or to the NSIL pin (at the pin header X1 on the left side of the board). Therefore the switch jumper J1 and/or J2 should be set to the middle position.

The STBY and the NSIL pins each provide a pull-up resistor to VIO respectively VCC, the S pin a pull-down resistor to GND, thus ensuring defined levels if the pins are open.

Note: The device cannot enter Normal mode as long as the TXD is at GND level.

2.5 SILENT MODE (WITH ATA6560, ATA6562 AND ATA6564 ONLY)

For the ATA6560 and ATA6562, a low level on the NSIL and STBY pins switches the devices into Silent mode. The ATA6564 switches into Silent mode, when a high level is applied to the S pin. This receive-only mode can be used to test the connection of the bus medium. In Silent mode, the ATA6560, ATA6562 and ATA6564 can still receive data from the bus, but the transmitter is disabled and therefore no data can be sent to the CAN bus. The bus pins are released to recessive state. All other IC functions, including the high-speed comparator (HSC), continue to operate as they do in Normal mode. Silent mode can be used to prevent a faulty CAN controller from disrupting all network communications.

2.6 STANDBY MODE (NOT FOR THE ATA6564)

A high level on the STBY pin selects the Standby mode. In this mode, the transceiver is not able to transmit or correctly receive data via the bus lines. The transmitter and the high-speed comparator (HSC) are switched off to reduce current consumption and only the low-power wake-up comparator (WUC) monitors the bus lines for a valid wake-up signal. For the ATA6560 and ATA6561, a signal change on the bus from Recessive to Dominant, followed by a dominant state longer than t_wake , switches the RXD pin to low to signal a wake-up request to the microcontroller.

The ATA6562, ATA6563 and ATA6566 do not wake-up with a single long dominant phase on the bus, they only wake-up when they receive a wake-up pattern (WUP).

The wake-up pattern consists of at least two consecutive dominant bus levels for a duration of at least t_Filter (0.5 s-3.8 s), each separated by a recessive bus level with a duration of at least t_Filter (0.5 s-3.8 s). This filtering helps to avoid spurious wake-up events, which would be triggered by scenarios such as a dominant clamped bus or by a dominant phase due to noise, spikes on the bus, automotive transients or EMI.

In Standby mode, the bus lines are biased to ground to reduce current consumption to a minimum. The wake-up comparator (WUC) monitors the bus lines for a valid wake-up signal. When the RXD pin switches to low to signal a wake-up request, a transition to Normal mode is not triggered until the STBY pin is forced back to low by the microcontroller. A bus dominant time-out timer prevents the device from generating a permanent wake-up request by switching the RXD pin to high.

For the ATA6560 and ATA6562, if the NSIL input pin is set to low in Standby mode, the internal pull-up resistor causes an additional quiescent current from VCC to GND. It is recommended to set the NSIL pin to high in standby mode.

NOTES:

Chapter 3. Hardware Description

3.1 PIN DESCRIPTION

The following sections show and describe the external elements required for some of the pins. See the specific datasheet for more information about this topic.

3.2 POWER SUPPLY

In order to get the development board running, an external stabilized 5V DC power supply has to be connected to the VCC header. The maximum rating for the VCC pin is 5.5V and a higher voltage may cause permanent damage to the device.

3.3 VIO SUPPLY PIN

There are two available device versions, with a different function of pin 5:

• On the ATA6561, ATA6563, ATA6564 and ATA6566, pin 5 is VIO and should be connected to the supply voltage of the connected microcontroller. This adjusts the signal levels of the TXD, RXD, NSIL, S and STBY pins to the I/O levels of the microcontroller. A jumper is implemented on the board (J3) connecting VIO to VCC for test purposes or quick measurements. If the VIO pin has to be supplied with a different voltage, jumper J3 has to be removed and the VIO pin header connected to the second external DC power supply (typically 3.3V).
• On the ATA6560 and ATA6562 without the VIO pin, the VIO input is internally connected to VCC. This sets the signal levels of the TXD, RXD, STBY and NSIL pins to levels compatible with 5V microcontrollers.

3.4 CAN INTERFACE (CANH, CANL, TXD, RXD)

The CAN transceiver is only active when it is in Normal mode. In Silent mode the transmitter is switched off and the ATA6560, ATA6562 and ATA6564 are in receive-only mode. In Standby mode the transceiver is completely switched off and no communication is possible. Only a low power wake-up comparator (WUC) is active in order to reflect the bus for a wake-up (not with the ATA6564).

3.5 CANH AND CANL PINS

The CANH and CANL pins are the interface to the bus network. Nodes connected to the bus end must show a differential termination, which is approximately equal to the characteristic impedance of the bus line in order to suppress signal reflection. Instead of a one-resistor termination it is highly recommended to use a so-called split termination. EMC measurements have shown that the split termination is able to significantly improve the signal symmetry between CANH and CANL, thus reducing the emission. Basically each of the two termination resistors is split into two resistors of equal value, i.e., two resistors of 60Ω (or 62Ω) (R2 and R3) instead of one resistor of 120Ω. The special characteristic of this approach is that the common-mode signal, available at the center tap of the termination, is terminated to ground via a capacitor. The recommended value for this capacitor is in the range of 4.7 nF to 47 nF (C7).

As the symmetry of the two signal lines is crucial for the emission performance of the system, the matching tolerance of the two termination resistors should be as low as possible (< 1% is desirable).

In addition, loading the CANH and CANL pins each with a capacitor of about 100 pF close to the connector of the ECU (there are placeholders on the PCB for the capacitors C7 and C8) is recommended. The main reason for doing this is to increase the robustness to automotive transients and ESD. The matching tolerance of the two capacitors should be as low as possible.

OEM specifications may require dedicated circuits. Refer to the corresponding OEM specifications for specific details.

The footprint for an optional common-mode choke, to improve EMC performance, is implemented (L1).

Placeholders (R1, C6 and C4) are implemented on the board for timing measurements.

3.6 TXD INPUT PIN

The signal sent to the TXD input pin controls the state of the CANH/CANL outputs. An internal pull-up resistor to VIO is implemented. The TXD input pin must be pulled to ground in order to drive the CAN bus into dominant state.

An internal timer prevents the bus lines from being driven permanently into the dominant state. If TXD is forced to low longer than t_to(DOM)TXD > 3 ms, the transceiver internally switches the TXD state to high and the CAN bus driver is switched to the recessive state. This feature is used to prevent a single faulty node (for example with a short to ground at the TXD pin) from paralyzing communication on the entire CAN bus the faulty node is connected to.

3.7 RXD OUTPUT PIN

This pin reports the state of the CAN bus to the microcontroller. CAN high (recessive state) is reported by a high level at RXD; CAN low (dominant state) is reported by a low level at RXD. The RXD output is a push-pull stage and is short-circuit protected.

3.8 SYSTEM CONTROL PINS (STBY, NSIL, S)

These input pins are used for mode control. They are typically directly connected to an output port pin of a microcontroller. The ATA6560/1/2/3/4/6 supports three operating modes: Normal, Silent (only with the ATA6560, ATA6562 and ATA6564) and Standby (not with the ATA6564), which can be selected via the STBY, S and NSIL pins. See Table2-1 for a description of the operating modes under normal supply conditions.

The STBY and the NSIL pins each provide a pull-up resistor to VIO, respectively VCC. The S pin of the ATA6564 provides a pull-down resistor to GND, thus ensuring defined levels if the pins are open.

The operating mode can be easily changed via the on-board switch jumpers (switch jumper J1 for STBY/S pin control and switch jumper J2 for NSIL pin control). If desired, this can be done also via an external signal generator, but therefore the switch jumper J1 and/or J2 should be set to the middle position.

4.1 TYPICAL APPLICATION CIRCUITS

Figure 4-1 and Figure 4-2 illustrate typical circuit examples using the ATA6560/1/2/3/4/6 devices. The application examples assume either a 5V or a 3V supplied host microcontroller. In each example there is a dedicated 5V regulator supplying the ATA6560/1/2/3/4/6 transceiver on its VCC supply pin (necessary for proper CAN transmit capability). Depending on which device is soldered on the board, all corresponding components required are mounted on the board.

Chapter 5. Test Setups and Measurements

5.1 TIMING MEASUREMENTS

The required components on the basic application board can be found below. A two-channel, or optimally, a four-channel oscilloscope is sufficient to measure the timing characteristics of the ATA6560/1/2/3/4/6. The transmit data signal TXD can be generated by any signal generator that is capable of delivering a rectangular or pulse signal with 3.3V to 5V amplitude, referred to GND. The characteristics of TXD, RXD and the CANH, CANL signals can be examined.

FIGURE 5-2: Components to be Removed (Red) or Replaced (Green) for the Timing Measurement Setup.

The footprint for an optional common-mode choke (L1) is implemented on the development board. This common-mode choke (L1) is per default replaced by two 0Ω resistors.

Instead of a one-resistor termination, it is highly recommended to use the commonly used so-called split termination, which is per default assembled. EMC measurements have shown that the split termination is able to significantly improve the signal symmetry between CANH and CANL, thus reducing emissions. Basically the termination is split into two resistors of equal value (R2 = R3 = 62Ω) and a capacitor (C1) to GND at the center tap, which represents one of the two usual bus end terminations. The special characteristic of this approach is that the common-mode signal, available at the center tap of the two resistors, is terminated to ground via the capacitor C1. The recommended value for this capacitor C1 is in the range of 4.7 nF to 47 nF (4.7 nF assembled per default).

As the symmetry of the two signal lines is crucial for the emission performance of the system, the matching tolerance of the two termination resistors R1 and R2 should be as low as possible (< 1% is desirable).

Additionally placeholders are implemented on the board for timing measurements (R1, C6 and C4). If a function generator is connected to the TXD header, it can be adjusted to output a rectangular signal up to a frequency corresponding to the maximum data rate of the final application. Pay attention that its output signal levels are in the appropriate range particularly that no negative voltage occurs. The function generator can be replaced by a dedicated data generator in order to form a better approach to the desired application. The high-impedance inputs of the oscilloscope can be connected directly - however it's advantageous to use probes, so that the signals are not noticeably affected by the capacitance of the coaxial cable.

Figure 5-4 shows the typical bus line signals for a 0-1 bit sequence at a data rate of 1 Mbit/s and VCC = VIO = 5V. The excellent symmetry of the CANH and CANL signals ensures superior EMC performance.

5.2 MEASUREMENT HINTS

5.2.1 Passive Behavior

In many applications, some transceivers can become unpowered (e.g., clamp-15 nodes) while other transceivers are continuously supplied (e.g., clamp-30 nodes). In such networks, the ATA6560/1/2/3/4/6 is favored for partially unpowered applications because of its excellent passive behavior to the bus when the VCC supply is switched off. In addition, the ATA6560/1/2/3/4/6 is protected against reverse currents via the TXD, RXD, NSIL, S and STBY pins. There is no backward current via those pins if the accompanying microcontroller continues to be supplied.

5.2.2 Optional Circuitry at CANH and CANL

The EMC performance of the ATA6560/1/2/3/4/6 has been optimized for the use of CAN termination without a common-mode choke. The excellent output stage symmetry allows use without chokes. If, however, system performance is still not sufficient, there is the option of using additional measures such as common-mode chokes (a footprint for a common-mode choke is implemented at the ATA6560/1/2/3/4/6 Evaluation Kit), capacitors, and ESD clamping diodes.

5.2.2.1 COMMON-MODE CHOKE

Note: If any critical measurements on EMI (electromagnetic interference) performance, such as electromagnetic immunity or electromagnetic emission, are to be taken, Microchip recommends a dedicated board with a highly symmetrical layout for the bus lines and ground vias at each connection to the ground plane. For investigations on complete links such as bit error measurements, a test board with at least two transceivers is required in any case.

A common-mode choke provides high impedance for common-mode signals and low impedance for differential signals. Because of this, common-mode signals produced by RF noise and/or by non-perfect transceiver driver symmetry are effectively reduced while passing the choke. In fact, a common-mode choke helps to reduce emission and to improve immunity against common-mode disturbances. Earlier transceiver devices usually needed a common-mode choke to comply with stringent emission and immunity requirements of the automotive industry when using unshielded twisted-pair cables. The ATA6560/1/2/3/4/6 makes it possible to build in-vehicle bus systems without chokes. Whether a choke is needed or not ultimately depends on the specific system implementation such as the wiring harness and the symmetry of the two bus lines (matching tolerances of resistors and capacitors). Besides the RF noise reduction, the stray inductance (non-coupled portion of inductance) may establish a resonant circuit together with pin capacitance. This can result in unwanted oscillations between the bus pins and the choke both with differential and common-mode signals as well as result in extra emission around the resonant frequency. To avoid oscillations of this kind, it is highly recommended to use only chokes with a stray inductance lower than 500 nH. Bifilar wound chokes typically show an even lower stray inductance. The choke should be placed nearest to the transceiver bus pins.

The use of common-mode chokes in CAN systems might cause extremely high transient voltages at the bus pins of the transceiver. These transients are generated by the change in current through the inductance of the common-mode chokes if the CAN bus is shorted to DC voltages. The actual transients that might be generated are highly dependent on the common-mode type and value, but also depend on the CAN system architecture, termination, components, location and the severity of the short circuit.

For systems where common-mode chokes are required, care should be used in the choice of the common-mode choke and the system circuit to avoid the introduction of severe transients during DC short-circuit conditions on the bus.

The best methods to avoid transients generated from common-mode chokes during CAN bus line shorts to DC voltages are:

• Remove common-mode chokes from systems, where applicable
• Move transient suppression circuits between the common-mode choke and the CAN bus pins on the transceiver
• Choose a dedicated common-mode choke and a CAN termination scheme to minimize transients

5.2.2.2 CAPACITORS

Matched capacitors (in pairs) at CANH and CANL to GND are frequently used to enhance immunity against electromagnetic interferences. Along with the impedance of corresponding noise sources (RF), capacitors at CANH and CANL to GND form an RC low-pass filter. Regarding immunity, the capacitor value should be as large as possible to achieve a low corner frequency. The overall capacitive load and impedance of the output stage establish an RC low-pass filter for the data signals. The associated corner

frequency must be well above the data transmission frequency. This results in a limit for the capacitor value depending on the number of nodes and the data transmission frequency. Notice that capacitors increase the signal loop delay due to longer rise and fall times. Due to these time reductions, bit timing requirements, especially at 1 Mbit/s, call for a value lower than 100 pF (see also SAE J2284 and ISO 11898). At a bit rate of 125 kBit/s the capacitor value should not exceed 470 pF. Typically, the capacitors are placed between the common-mode choke (if applied at all) and the ESD clamping diodes

5.2.2.3 ESD PROTECTION

The ATA6560/1/2/3/4/6 is designed to withstand ESD pulses of up to 8 kV according to the human body model at the CANH and CANL bus pins and thus typically does not need any additional external protection methods. Nevertheless, if a higher protection level is required, external clamping devices can be applied to the CANH and CANL lines.

Care must be taken when selecting the right protection devices. The transient protectors must be fast enough to clamp the transient voltages. In addition, their capacitance must be considered. If the capacitance is too high, it can work together with the choke's inductance and cause ringing on the bus signals. Although this ringing does not corrupt the CAN signals, it might show up as electromagnetic emission at higher frequencies.
