The PIC18F2455-I/SP is a high-performance enhanced flash USB Microcontroller with nanoWatt technology. Ideal for low power (nanoWatt) and connectivity applications that benefit from the availability of three serial ports of FS-USB(12Mbps), I2C? and SPI? (up to 10Mbps) and an asynchronous (LIN capable) serial port (EUSART). Large amounts of RAM memory for buffering and enhanced flash program memory make it ideal for embedded control and monitoring applications that require periodic connection with a (legacy free) personal computer via USB for data upload/download or firmware updates. While operating up to 48MHz, the PIC18F2455 is also mostly software and hardware compatible with the PIC16C745 low-speed USB OTP devices. The PIC18F2455 family introduces design enhancements that make this microcontroller a logical choice for many high-performance and power sensitive applications.
