About this product
The PIC18F252-I/P is a 28-pin, 8-bit Flash microcontroller from Microchip that runs at up to 10 MIPS with 77 single-word instructions. It includes 256 bytes of EEPROM, self-programming, an in-circuit debugger interface, two capture/compare/PWM functions, five channels of 10-bit ADC, and an SPI/I2C serial port. It is C-compiler friendly and suits embedded projects needing more I/O than an 18-pin device.
