Port Expander

mik for  PIC32MX7

®

 

features a 16-bit I/O port 

expander module 

MCP23S17

 

which

 

communicates with  PIC32MX795F512L 

microcontroller via SPI serial interface. This 

module enables you to expand the number of 

microcontroller I/O pins with two 8-bit I/O ports (PORTA 

and PORTB). Each of them consists of registers for input, output 

and polarity selection. In addition, the 

MCP23S17

 

module contains 

interrupt and reset pins and has 25mA sink/source capability per I/O pin.
