Overview

The PIC18F14K50-I/SS is an 8-bit microcontroller that features Microchip's eXtreme Low Power (XLP) technology and an integrated USB 2.0 interface. It provides 16KB of Flash memory and 768 bytes of RAM, operating at speeds up to 48MHz for USB applications. This device is specifically designed to bridge the gap between low pin-count microcontrollers and full-speed USB connectivity.

Why Choose This Part

The primary advantage is the combination of a full-speed USB 2.0 interface with Microchip XLP technology, which significantly reduces power consumption in standby modes. It features a C-compiler optimized architecture and a 16-level deep hardware stack, making it efficient for firmware development in high-level languages.

Applications

USB-to-Serial Bridges
Utilizing the integrated USB 2.0 engine and UART to create compact interface converters.
PC Peripherals
Designing low-power HID devices like custom keyboards, mice, or specialized input controllers.
Battery-Powered Data Loggers
Leveraging XLP technology for extended battery life in portable devices that require occasional USB data offloading.
Smart Card Readers
Implementing secure interface devices using the hardware SPI and I2C peripherals alongside USB.
