Frequently Asked Questions - dsPIC33FJ128MC802 Microchip
What is the maximum clock speed of the dsPIC33FJ128MC802?
The dsPIC33FJ128MC802 operates at up to 40 MIPS (million instructions per second) with a maximum internal clock frequency of 40 MHz. This high speed is achieved using a Phase-Locked Loop (PLL) from an external oscillator.
What is the flash memory size of this device?
The device features 128 KB of on-chip flash memory, which is used for program storage. It also includes 8 KB of SRAM for data storage.
What tools are required to program the dsPIC33FJ128MC802?
You need a programmer/debugger such as Microchip's MPLAB ICD 4, MPLAB PICkit 4, or MPLAB Snap. The programming interface is via ICSP (In-Circuit Serial Programming) or JTAG. Software tools include MPLAB X IDE and the MPLAB XC16 compiler.
Can the dsPIC33FJ128MC802 be used for motor control applications?
Yes, it is specifically designed for motor control. It includes a 6-output high-speed PWM module, a quadrature encoder interface (QEI), and multiple timers. Additionally, it has a 10-bit ADC with up to 16 channels for current and position sensing. The DSP engine can execute complex control algorithms like FOC (Field Oriented Control).
What is the operating voltage range?
The operating voltage is 3.0V to 3.6V, making it suitable for low-power applications. It has built-in brown-out reset (BOR) and power-on reset (POR) for reliable operation.
Does this device have built-in CAN bus support?
Yes, the dsPIC33FJ128MC802 includes a CAN (Controller Area Network) module that supports CAN 2.0B protocol. It is ideal for automotive and industrial applications requiring robust communication.
What package options are available?
The standard package is a 64-pin TQFP (Thin Quad Flat Pack) with dimensions of 10mm x 10mm. Other package variants may exist, but the MC802 typically comes in TQFP-64.
What is the temperature range for operation?
The device is rated for the industrial temperature range: -40°C to +85°C. Extended temperature versions may also be available.
How many ADC channels does it have?
It has a 10-bit successive approximation ADC with up to 16 analog input channels. The ADC can be configured for single-ended or differential inputs and supports automatic sampling.
Is the dsPIC33FJ128MC802 lead-free and RoHS compliant?
Yes, Microchip manufactures this device as RoHS compliant and lead-free. It is suitable for use in environmentally sensitive applications.
