Overview

The PIC16F1823-I/ST is a versatile 8-bit microcontroller from Microchip's Enhanced Mid-range family featuring eXtreme Low Power (XLP) technology. It integrates 3.5KB of Flash memory and 256 bytes of EEPROM into a compact 14-pin TSSOP package, making it suitable for space-constrained, battery-operated designs. The device includes a variety of serial communication interfaces and hardware peripherals such as a temperature indicator and a factory-calibrated internal oscillator.

Why Choose This Part

This MCU offers a high degree of integration including I2C, SPI, and UART interfaces within a 14-pin footprint. It features an optimized architecture for C compilers and a 16-level deep hardware stack, facilitating efficient firmware development. The high-endurance Flash memory supports up to 100,000 write cycles, ensuring reliability in data-logging applications.

Applications

Battery-Powered Sensors
Utilizes XLP technology to minimize current draw in sleep modes for long-term remote monitoring.

Getting Started

Developers can begin by using the MPLAB X IDE and the XC8 C Compiler provided by Microchip. Hardware programming and debugging are supported via the PICkit 4 or MPLAB Snap tools using the 2-pin ICSP interface. For rapid prototyping, a breadboard-friendly breakout or a Curiosity Development Board can be used to evaluate the device peripherals.
