Microchip PIC16LC923-04I/L 8-Bit Microcontroller Data Sheet Overview

The Microchip PIC16LC923-04I/L is a high-performance, 8-bit microcontroller engineered for embedded control applications requiring efficient power management and robust peripheral integration. Fabricated with Microchip’s advanced low-power CMOS technology, this device combines high computational performance with minimal power consumption, making it particularly suitable for battery-powered and portable applications.

Housed in a 44-pin PLCC package, the PIC16LC923-04I/L operates at a maximum frequency of 4 MHz and is specified for the industrial temperature range (-40°C to +85°C). Its core architecture leverages a RISC-based CPU with 35 simple instructions, ensuring rapid development and optimized code execution. The microcontroller features 4 KB of EPROM program memory and 176 bytes of RAM, providing ample space for embedded program and data storage.

A key strength of this microcontroller is its rich set of integrated peripherals. It includes an 8-bit timer and a 16-bit timer/counter, a Watchdog Timer for enhanced system reliability, and a 12-channel 8-bit analog-to-digital converter (ADC) for precision analog signal acquisition. Furthermore, it supports serial communication via a synchronous serial port (SSP) and features a universal asynchronous receiver transmitter (UART) for flexible interface options with peripheral devices.

Power management is a critical design focus. The device incorporates multiple power-saving modes, including SLEEP and low-power IDLE states, which drastically reduce power consumption during inactive periods. This allows systems to maintain extended operational life when powered by batteries or other limited energy sources.

Development support is facilitated by Microchip’s comprehensive suite of hardware and software tools, including the MPLAB® IDE, which simplifies coding, simulation, and in-circuit debugging.
