The MCP3901 ADC Evaluation Board for 16-Bit MCUs contains a 100-pin PIM socket
compatible with Microchip’s PIM modules. The system comes with 2 PIM modules: the
PIC24FJ128GA010 and dsPIC33FJ256GA710.
A complete description of the firmware programmed with these two modules is
available in Chapter 1. “Hardware Description”.
Digital Connection Overview PIM/MCP3901 Connections.
Ports A, B, and D are used for signals such as push buttons, output LEDs, CS and
MCLR (for MCP3901 data mode setting). Output Capture 1 is used for MCP3901’s
clock generation. Serial communication is achieved through the MSSP module 1.
