Microchip PIC18F14K50-I/SS 8-Bit Microcontroller Overview and Application Guide

The Microchip PIC18F14K50-I/SS is a high-performance, low-cost 8-bit microcontroller from Microchip Technology’s renowned PIC18 family. Built around an enhanced mid-range core with a 16-bit instruction word architecture, this device combines processing power with a rich set of peripherals, making it an ideal solution for a vast array of embedded control applications. Housed in a compact SSOP-20 package, it is particularly suited for space-constrained designs.

At its heart, the microcontroller operates at speeds up to 12 MIPS with a 16 MHz internal oscillator, reducing external component count and simplifying board design. It features 16 KB of self-read/write capable Flash program memory and 768 bytes of RAM, providing ample space for application code and data handling. A standout feature is its integrated USB 2.0 Full-Speed (12 Mbps) module, which includes an on-chip transceiver, making it exceptionally capable for USB-connected devices without requiring external components.

The peripheral set is robust and versatile. It includes:

Analog-to-Digital Converter (ADC): A 10-bit module with up to 10 channels for precise sensor data acquisition.

Timers: Multiple 8-bit and 16-bit timers/counters for event timing and waveform generation.

Communication Interfaces: Enhanced Addressable USART (EUSART) for serial communication (RS-232, RS-485) and an SPI/I2C module for interfacing with a multitude of sensors, memories, and other peripherals.

Comparators and CCP: Analog comparators and a Capture/Compare/PWM (CCP) module for control applications like motor driving.

A key advantage of the PIC18F14K50 is its nanoWatt XLP (eXtreme Low Power) technology. This enables extremely low power consumption in active, idle, and sleep modes, which is a critical requirement for battery-powered and portable applications such as remote sensors, medical devices, and personal electronics.
