Overview

The PIC18F14K22-I/SS is a high-performance 8-bit microcontroller featuring 16KB of Flash memory and a C-compiler optimized RISC architecture capable of up to 64MHz clock speeds. Part of the PIC18 family, it integrates a 16MHz internal oscillator with 4X PLL and provides robust peripheral support including I2C, SPI, and LINbus connectivity in a compact 20-SSOP package.

Why Choose This Part

This MCU offers a high performance-to-size ratio by delivering 64MHz operation and a hardware 8x8 multiplier within a small 20-pin SSOP footprint. Engineers benefit from 256 bytes of dedicated EEPROM for non-volatile data storage and a precision internal oscillator that reduces the need for external timing components.

Applications

Industrial Sensor Interfaces
Utilizing the 17 I/O pins and integrated I2C/SPI interfaces to aggregate data from digital and analog sensors.
Automotive LIN Subsystems
Implementing LINbus communication for interior controls, window modules, or seat adjustments.
System Supervisory Circuits
Using the programmable Brown-out Reset (BOR) and Watchdog Timer (WDT) to monitor and manage system power states.
Handheld Portable Devices
Leveraging XLP (Extreme Low Power) technology with standby currents as low as 23uA for battery-sensitive applications.
