This blank Printed Circuit Board (PCB) allows any 8-pin device in the following four package types to be installed:

1. SOIC-8
2. PDIP-8
3. MSOP-8
4. TSSOP-8

This board is generic so that any device may be installed. Refer to the device data sheet, however, for suitability of device evaluation.

As well as the device, other desired passive components (resistors and capacitors) and connection posts may be installed. This allows the board to evaluate a minimum configuration for the device. Also, this allows the device to be easily jumpered into an existing system.

2.2 FEATURES

The 8-Pin SOIC/MSOP/TSSOP/DIP Evaluation Board has the following features:

• Connection terminals may be either through-hole or surface-mount
• Four 8-pin package footprints supported:

- SOIC

- DIP

- M S O P

- TSSOP

- Footprints for optional passive components for:

• Power supply filtering
• Device bypass capacitor
• Output filtering
• Output pull-up resistor
• Output pull-down resistor
• Output loading resistor
• Output series resistor
• Up to four additional passive components

- Silk-screen area to write specifics of implemented circuit (on back of PCB), such as TC1232 4.75V, (to indicate that the device is the TC1232 with the 4.75V trip point)

• P I C m®iMCU Baseline Flash Microcontroller Programmer (BFMP) Header
• Can be used for SOIC-8, MSOP-8, TSSOP-8 to DIP-8 converter

2.3 GETTING STARTED

The 8-Pin SOIC/MSOP/TSSOP/DIP Evaluation Board is a blank PCB that allows the user to configure the circuit to the exact requirements. The passive components use the surface-mount 805 package layout.

This evaluation board supports the following Microchip device families:

• A/D Converters (ADCs) (ADCs)
- Battery Chargers
- Comparators
• D/A Converters (DACs) (DACs)
- DC-to-DC Converters
• Digital Potentiometers (Digi-Pots)
- Fan Controllers
- Integrated Devices
- Interface Devices
- Linear Regulators
• Operational Amplifiers (Op Amps)
• Power MOSFET Drivers
- Switching Regulators
• Temperature Sensors
• PICmicro Microcontrollers

- Programmable Gain Amplifiers (PGAs)s (PGAs)

• Voltage Supervisors and Voltage Detectors

Figure 2-1 shows the evaluation board circuit. Pin "n" of each device (U1, U2, U3 and U4) are tied together. These pins are then connected with pad "n" of the PCB (through a circuit). This circuit allows each pin to individually have any of the following: a pull-up resistor, a pull-down resistor, an in-line resistor and/or a loading/filtering capacitor. Device-filtering capacitors are available (C2 and C3), as well as a power supply filtering capacitor (C1).

There may be cases where some additional passive components are desired for the evaluation circuit. The PCB has four 805 footprints that are not connected (labeled P1, P2, P3 and P4) and can easily be jumpered into the desired circuit.

FIGURE 2-1: 8-Pin SOIC/MSOP/TSSOP/DIP Evaluation Board Circuit.

2.3.1 The Hardware

Figure 2-2 shows the layout of the 8-Pin SOIC/MSOP/TSSOP/DIP Evaluation Board. This is a small four-layer board (1.5" x 2" (38.1 mm x 50.8 mm)). There are ten connection points/pads that can use either through-hole or surface-mount connector posts.

The pad labeled VDD is connected to the PCB power plane, while the pad labeled VSS is connected to the PCB ground plane. All the passive components that are connected to VDD or VSS are connected to either the power plane or ground plane.

The eight remaining PCB pads correspond to the device pins (i.e.; pad 1 connects to pin 1).

Each pad has four passive components associated with them: a pull-up resistor, a pull-down resistor, an in-line resistor and a filtering/load capacitor. The pull-up resistor is always R2X, the pull-down resistor is R3X, the in-line resistor is R1X and the filtering/load capacitor is C1X. The "X" is an alpha character that corresponds to a particular pad (A to H). As an example, Pad 5's pull-up resistor is R2E.

The green area of Figure 2-2 shows the silk-screen on the bottom layer of the PCB. This is where the details of the implemented circuit can be written.

Capacitor C1 is the power supply filtering capacitor.

Capacitors C2 and C3 are bypass capacitors that may be required to be installed, depending on the device selected and the system requirements (such as the noise present on the power supply). Table 2-1 describes the components.

A 6-pin header interface is available that supports the PICmicro MCU Baseline Flash Microcontroller Programmer (BFMP) interface. For additional information, refer to Section 2.4.5 "Baseline Flash Microcontroller Programmer (BFMP) Interface (Header J1)".

2.4 8-PIN SOIC/MSOP/TSSOP/DIP EVALUATION BOARD DESCRIPTION

The 8-Pin SOIC/MSOP/TSSOP/DIP Evaluation Board PCB is designed to be flexible in the type of device evaluation that can be implemented.

The following sections describe each element of this evaluation board in further detail. Refer to Figure 2-3.

2.4.1 Power and Ground

The 8-Pin SOIC/MSOP/TSSOP/DIP Evaluation Board has a VDD Pad and a VSS pad. These pads can have connection posts installed that allows easy connection to the power ( V_DD ) and ground ( V_SS ) planes. The layout allows either through-hole or surface-mount connectors.

The power and ground planes are connected to the appropriate passive components on the PCB (such as power plane to R2X and ground plane to R3X and C1X).

2.4.2 PCB PADs

For each package pin (pins 1 to 8), there is a PCB pad (pads 1 to 8). The device will have some power pins ( V_DD ) and some ground pins ( V_SS ). To ease connections on the PCB, vias to the power and ground plane have been installed close to each PCB pad. This allows any pad to be connected to the power or ground plane, so when power is connected to the VDD and VSS pads, the power is connected to the appropriate device pin.

Jumpering to VDD

R1H R2H PAD8 VSS VDD C1H R3H

FIGURE 2-3: Jumpering the PCB pad to either VDD or VSS.

Revision 1 of this PCB has an issue that these vias are not connected to the desired power and ground planes (they are open). For additional information, refer to Appendix D. "Rev. 1 PCB Errata".

2.4.3 Passive Components (R1X, R2X, R3X, C1X, R1, R2, C1, C2, C3, P1, P2, P3 and P4)

The footprints for these components are present to allow maximum flexibility in the use of this PCB to evaluate a wide range of SOT-23-3 devices. The purpose of these components may vary depending on the device under evaluation and how it is to be used in the desired circuit. Refer to the device data sheet for the recommended components that should be used when evaluating that device.

• Component R1X allows an in-line resistor that can be installed between the device pin and the PCB pad. This may be required when interfacing this PCB to other circuits
• Component R2X allows a pull-up resistor to be installed for the device pin
• Component R3X allows a pull-down resistor to be installed for the device pin
• Component C1X allows a capacitive load/filter to be installed for the device pin
• Component C1 allows a power supply filtering capacitor to be installed
• Components C2 and C3 allows a device filtering capacitor to be installed
• Components P1, P2, P3, and P4 are not connected and give a footprint (805 surface-mount) for a passive component (resistor, capacitor, etc.) to be installed and jumpered into the PCB circuit. This allows for the evaluation of some simple device circuits to be implemented on this PCB

2.4.4 Installing Resistor R1X

Resistor R1X is shorted by default. Therefore, if resistor R1X is to be installed, the trace across the component must be cut before it is installed (see Figure 2-4).

While evaluating a device, it may be desirable to see the signals on both sides of this resistor. A test point is available so that both signals may be monitored. This test point is the avenue between components R3X and C1X (see Figure 2-4).

R1H R2H This trace must be cut before resistor R1X can be installed Test point PAD8 VSS VDD C1H R3H

FIGURE 2-4: Test point when resistor R1X is installed.

2.4.5 Baseline Flash Microcontroller Programmer (BFMP) Interface (Header J1)

The BFMP interface allows a PICmicro MCU device to be programmed with programmers that support this interface, such as the BFMP programmer (part number PG164101).

The PCB supports two device pinouts. The default pinout already has the traces connected to the appropriate PICmicro MCU pins. The optional pinout requires three PCB traces to be cut and then three connections to be made (see Figure 2-5).

2.4.6 The PCB as a SOIC-8, MSOP-8, or TSSOP-8 to DIP-8 Socket Converter

There may be occasions when it is desirable to convert the footprint of the device to that of a DIP package. This allows the device to be installed into an existing DIP socket. Two 1x4 row pins need to be installed into the PCB's DIP footprint when the device is installed into the appropriate package footprint.

This allows the PCB to convert the SOIC-8, MSOP-8 or TSSOP-8 footprints to a 300-mil DIP-8 footprint.

2.4.7 Evaluating a Voltage Supervisor or Voltage Detector Device

2.4.7.1 VOLTAGE SUPERVISORS

The following voltage supervisor is supported by this evaluation board.

TABLE 2-3: 8-PIN VOLTAGE SUPERVISOR

Device SO	IC DIP MSOP TSSOP Comment
TC1232 Yes Yes		—	—

When evaluating a voltage supervisor/voltage detector device, a minimum set of test equipment should be available. Table 2-4 shows the recommended test equipment.

TABLE 2-4: TEST EQUIPMENT

Hardware	Connect to:	Comment
Variable Power Supply	V_DD, V_SS	This allows the voltage to the SOT23 Evaluation Board to be varied so the device output can be monitored.
Arbitrary Waveform Generator	V_DD, V_SS	This is similar to a variable power supply, but allows programmability into the input signal that the device will be subjected to. This also allows a particular waveform to be repeated (such as a 60 Hz sine wave that varies from 1V to 5V).
Digital Multi-Meter (D.M.M.)	V_OUT^(1)	Used to indicate the output state (low or high) of the voltage supervisor/voltage detector.
Oscilloscope	V_OUT^(1)	Allows the device conditions and response to be evaluated due to the ability to capture this information. This is useful for faster signals and cases where small spikes need to be detected.
Test Light (LED) V	OUT^(1)	Used to visually indicate the output state (low or high) of the voltage supervisor/voltage detector. Ensure that the current requirements of this LED can be supplied by the device's output pin.

Note 1: The pad connection to connect to the V_OUT or pin will be dependent on the device and the footprint option used.

A typical system that would be used to evaluate the voltage supervisor/voltage detector device is shown in Figure 2-7. This also shows an example input and output waveform for a voltage supervisor/voltage detector device.

Appendix D. Rev. 1 PCB Errata

D.1 INTRODUCTION

This appendix documents the issues with the Rev 1 PCB. The Rev 2 PCB fixes these issues.

D.2 REV 1 PCB ISSUES

There are two issues with the Rev 1 PCB. These are:

1. VDD and VSS vias near each pad are No Connects (they should have been connected to the appropriate power or ground plane). See Figure D-1 shows the location of these vias that are No Connects. Figure D-3 shows alternate connections that can be made.
2. The silk-screen on the bottom layer was not processed. This was only intended for indicating the circuit of the board. This can be done with a sticky label.

Figure D-2 shows how to determine the PCB revision.

Circuit board layout diagram with labeled pins and vias connections, accompanied by explanatory text about VDD/VSS plane connections.
