Which PIC® can I use to implement RS485 Modbus®?

Any Microchip MCU with a UART peripheral for the RS485 connection can be used to implement Modbus®. The Modbus required RS485 baud rate of 9600 - 19200 is supported by all PIC®, AVR®, dsPIC®, and SAM MCUs

Selection of the MCU must consider the availability of protocol software. Microchip offers software for 16- and 32-bit solutions. The following resources can assist in selecting an MCU:
