Microchip PIC16F876A 8-Bit Flash Microcontroller, SOIC-28

The Microchip PIC16F876A 8-Bit Flash Microcontroller is a surface-mount, 28-pin SOIC device featuring 14 KB of self-programmable Flash program memory for embedded control applications.

Overview

The PIC16F876A is an enhanced 8-bit Flash microcontroller that combines low-power consumption with high-speed Flash and EEPROM technology. It is built around the PIC16 core and can operate at frequencies up to 20 MHz. The Flash program memory can be read and written during normal operation across the full voltage range, and 256 bytes of data EEPROM are included, rated for one million erase/write cycles with typical data retention of 40 years. The device is designed to minimise the need for external components in embedded designs.

Key Features

• Peripherals: Five channels of 10-bit Analogue-to-Digital Converter (ADC), two comparators and two capture/compare/PWM modules for precise timing and control.
• Communication: A Synchronous Serial Port (SSP) configurable as either a 3-wire SPI or 2-wire I²C bus, alongside a Universal Synchronous Asynchronous Receiver Transmitter (USART).
• Reliability: Brown-out detection for brown-out reset (BOR), power-saving sleep mode and programmable code protection.
• Development: In-Circuit Serial Programming (ICSP) via two pins from a single 5 V supply, supporting programming and debugging, rapid prototyping and field updates.

Package and Operating Range

• Package: 28-pin SOIC surface-mount package with 22 I/O lines.
• Operating voltage: 4 V to 5.5 V.
• Operating temperature: -40 °C to 85 °C.
• Weight: 0.001 gm.

Dimensions

Width: 3.3, Depth: 1.5, Height: 4.3.

The Microchip PIC16F876A 8-Bit Flash Microcontroller suits projects that need a compact, surface-mount controller with integrated analogue, serial and timing peripherals, and is a practical choice for embedded control designs requiring reliable programming and operation across its stated voltage and temperature ranges.
