Overview

The PIC16F1847-I/SO is an 8-bit microcontroller from Microchip's Enhanced Mid-Range family featuring eXtreme Low Power (XLP) and mTouch technology. It operates at up to 32MHz with 14KB of Flash memory and 1KB of RAM in a compact 18-pin SOIC package. This MCU is designed for applications requiring high peripheral integration and minimal power consumption in a small footprint.

Why Choose This Part

It offers a rich set of 15 I/O pins and dual I2C/SPI interfaces, providing high connectivity density for an 18-pin device. The architecture is optimized for C compilers with a 16-level deep hardware stack and automatic context saving to simplify firmware development. Additionally, the wide operating voltage of 1.8V to 5.5V ensures compatibility with both low-voltage battery systems and standard 5V logic.

Applications

Capacitive Touch Interfaces
Utilizing integrated mTouch technology for robust proximity sensing and touch button implementation without external controllers.
Battery-Powered Remote Sensors
Leveraging XLP technology and 20uA sleep current for extended life in wireless sensor nodes and handheld devices.
Industrial Communication Bridges
Acting as a protocol translator between I2C, SPI, and UART/LINbus interfaces in industrial environments.
Automotive Interior Control
Managing simple automotive functions such as lighting control or window switches via LINbus connectivity.
