Microchip PIC18F452 8-Bit Flash Microcontroller TQFP44
Microchip PIC18F452 8-bit flash microcontroller in TQFP44 package with 10-bit A/D, 256 bytes EEPROM, SPI/I²C serial port and ICD interface.
Microchip PIC18F452 8-Bit Flash Microcontroller is a high-performance 8-bit flash microcontroller featuring 8 channels of 10-bit analogue-to-digital (A/D) conversion, 256 bytes of EEPROM and an In-Circuit Debug (ICD) interface. It is designed for a C compiler friendly environment and provides comprehensive connectivity options for diverse embedded applications.
Overview
The device is built on a high-performance RISC CPU capable of up to 10 MIPS operation, with 16-bit wide instructions and an 8-bit wide data path. It supports self-programming capability and is self-reprogrammable under software control. The flash and data EEPROM retention exceeds 40 years, and a watchdog timer (WDT) with its own on-chip RC oscillator supports reliable operation.
