MCHPPIC18F45K22-E/PT
Overview
The PIC18F45K22-E/PT is an 8-bit microcontroller featuring 32KB of Flash memory and integrated XLP technology for low power consumption. This Extended temperature range (-40C to +125C) variant operates at up to 64 MHz and includes a hardware multiplier for efficient math processing. It is designed for robust performance in industrial and automotive environments with integrated analog peripherals and high-current I/O pins.
Why Choose This Part
This MCU offers a 16 MHz precision internal oscillator and a hardware multiplier that significantly speeds up control loops compared to standard 8-bit cores. The high-current I/O pins can sink or source up to 25 mA, often eliminating the need for external transistors when driving LEDs or small relays.
Applications
Getting Started
Develop applications using the Microchip MPLAB X IDE and the XC8 compiler. Hardware debugging and programming are best handled with the MPLAB PICkit 4 or ICD 4 tools via the integrated ICSP interface. Evaluation can be accelerated using the Curiosity High Pin Count Development Board or similar PIC18-focused hardware platforms.
