Overview

The PIC18F14K22-E/P is a high-performance 8-bit microcontroller featuring Microchip XLP (eXtreme Low Power) technology in a prototyping-friendly 20-pin PDIP package. It operates at speeds up to 64MHz using an internal 4X PLL and provides a versatile set of peripherals including a hardware multiplier and multiple serial communication interfaces.

Why Choose This Part

This MCU offers a C-compiler optimized architecture with an extended instruction set and a hardware 8x8 multiplier for efficient processing. Its XLP technology achieves sleep currents as low as 34nA, making it one of the most power-efficient options in the 8-bit PIC18 family.

Applications

Battery-Powered Remote Sensors
Utilizes XLP technology for extremely low sleep currents in portable monitoring devices.
Industrial Protocol Bridges
Leverages I2C, SPI, and LINbus support to translate data between different industrial communication standards.
Handheld Consumer Electronics
Small footprint and low power consumption make it ideal for simple user interfaces and control logic.
Rapid Prototyping
The PDIP package allows for direct insertion into breadboards for firmware development and testing.
