Microchip | PIC18LF6621-I/PT

The PIC18LF6621-I/PT is a part of PIC18LF series 8-bit Microcontroller. It has 64 Kbytes of Flash Program Memory in a 64-Pin TQFP package. It has an industrial temperature range from -40°C to +85°C.

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.
