Overview

The PIC18F14K50-I/P is a versatile 8-bit microcontroller that combines a high-performance PIC18 core with a full-speed USB 2.0 interface in a breadboard-friendly 20-pin PDIP package. Operating at up to 48MHz, it features 16KB of Flash memory and integrated peripherals including a 10-bit ADC and dual comparators.

Why Choose This Part

This MCU offers a dedicated USB 2.0 Serial Interface Engine (SIE) and an on-chip 3.2V LDO regulator, simplifying the bill of materials for USB bus-powered designs. Its eXtreme Low Power (XLP) technology reduces sleep currents to as low as 4uA, while the 8x8 hardware multiplier accelerates math-heavy tasks.

Applications

USB Peripheral Emulation
Ideal for creating custom USB HID, CDC, or MIDI devices such as keyboards, mice, or serial bridges.
Low-Power Data Loggers
Utilizes XLP technology to minimize power consumption in battery-operated monitoring devices.
Legacy System Interfaces
Perfect for adding modern USB connectivity to existing industrial equipment via its UART, SPI, and I2C interfaces.
Educational Prototyping
The PDIP package allows for easy use on breadboards for students and engineers learning USB stack implementation.
