Overview

The PIC18F45K20-I/P is a high-performance 8-bit microcontroller featuring 32KB of Flash memory and 1.5KB of RAM in a 40-pin PDIP package. It utilizes Microchip NanoWatt XLP technology for extreme low-power consumption and operates at speeds up to 64MHz. This MCU is designed with a C-compiler optimized architecture and includes a 16MHz internal oscillator with 4X PLL for flexible clocking options.

Why Choose This Part

This microcontroller offers a high level of peripheral integration, including a hardware multiplier for faster math operations and priority-level interrupts for responsive real-time control. It supports a wide operating voltage range from 1.8V to 3.6V, making it compatible with modern low-voltage systems while maintaining 8-bit simplicity.

Applications

Battery-Powered Handheld Devices
Utilizes XLP technology for deep sleep currents down to 50nA to extend battery life in portable instrumentation.
Industrial Sensor Interfaces
Uses the 10-bit ADC and EUSART/I2C/SPI interfaces to collect and transmit data from various industrial transducers.
Educational and Prototyping Projects
The PDIP package allows for easy use in breadboards and sockets during the early stages of firmware development.
Home Automation Controllers
Manages light-duty control tasks and communication between smart home nodes using integrated PWM and serial peripherals.
