PIC18F25K42-I/SP Microchip 8bit MCU

PIC18F25K42-I/SP Overview

PIC18(L)FxxK42 MCUs integrate a rich set of core independent peripherals, intelligent analog peripherals and large Flash/RAM/EEPROM memories. These 28-, 40- and 48-pin devices also offer a host of low power features, performance improvements and design flexibility options that easily and rapidly enable the complex set of functions required by many of today's embedded control applications.
