PIC18F4550 Microchip Microcontroller - (AD016)

Description:

Ideal for low-power (nanoWatt) and connectivity applications that benefit from the availability of three serial ports: FS-USB (12 Mbit/s), I²C™, and SPI™ (up to 10 Mbit/s) and an asynchronous (LIN) serial port (EUSART). The large amounts of RAM for buffering and Flash program memory make it ideal for embedded control and monitoring in applications requiring periodic connection to a personal computer via USB for data upload/download and/or firmware updates.
