Microchip | PIC18F66J16-I/PT

Ideal for 3 V applications that are cost senstitive, requiring flexible serial communication with four serial ports: double synchronous serial ports (I²C™ and SPI™) and double asynchronous serial ports. Large amounts of Flash program memory make it ideal for instrumentation panels, TCP/IP enabled embedded applications as well as metering, industrial control and monitoring applications.
