Microchip | PIC18LF452-I/P

Ideal for connectivity applications that benefit from the availability of the double asynchronous serial port, the flexible synchronous serial port (I²C or SPI) as well as large amounts of RAM buffer memory and Flash program memory. These include instrumentation panels, TCP/IP enabled embedded applications as well as metering and industrial control and monitoring applications.
