Overview

The PIC16F1455-I/SL is a high-performance 8-bit microcontroller featuring eXtreme Low Power (XLP) technology and an integrated USB 2.0 interface. It is designed to operate at up to 48MHz without the need for an external crystal for USB clocking, significantly reducing system cost and board space. With 14KB of flash memory and a 14-pin SOIC package, it provides a compact solution for adding USB connectivity to small-scale embedded designs.

Why Choose This Part

The primary advantage is the Crystal-less USB operation, which eliminates the cost and complexity of external resonators. It also features XLP technology for typical run currents as low as 30 uA/MHz at 1.8V, making it ideal for power-sensitive applications.

Applications

USB Peripheral Bridges
Creating low-cost USB-to-UART or USB-to-I2C bridges for legacy peripheral interfacing.
Human Interface Devices (HID)
Designing custom USB keyboards, mice, or specialized control panels that require low power consumption.
Portable Data Loggers
Utilizing XLP technology for long battery life in sensors that periodically upload data via USB.

Getting Started

Development is best supported by the MPLAB X IDE and the XC8 Compiler. For hardware prototyping, the PIC16F1459 Curiosity Development Board provides a compatible environment, while an MPLAB PICkit 4 or Snap programmer is required for ICSP debugging.
