Microchip PIC16F871-I/P 8-Bit Microcontroller Data Sheet and Technical Specifications

The Microchip PIC16F871-I/P is a high-performance 8-bit microcontroller built on an enhanced RISC architecture, offering a balance of processing power, peripheral integration, and power efficiency. Housed in a 40-pin PDIP package, this device is designed for a wide array of embedded control applications in automotive, industrial, consumer, and other sectors.

At its core, the microcontroller operates at a clock speed of up to 20 MHz, delivering a 200 ns instruction cycle time for responsive real-time performance. It features 4 KB of Flash program memory, 128 bytes of EEPROM data memory, and 368 bytes of RAM, providing ample space for both code and data storage in complex applications.

A key strength of the PIC16F871-I/P lies in its rich set of integrated peripherals. It includes a 10-bit Analog-to-Digital Converter (ADC) with up to 14 input channels, enabling precise measurement of analog signals. For timing and control tasks, it is equipped with multiple timers/counters (Timer0, Timer1, Timer2), two Capture/Compare/PWM (CCP) modules, and a Universal Synchronous Asynchronous Receiver Transmitter (USART) for serial communication protocols like RS-232 and RS-485. Additionally, it supports a Serial Peripheral Interface (SPI) and Inter-Integrated Circuit (I²C), facilitating easy communication with other peripheral chips and sensors.

The device is designed for robust operation within a 2.0V to 5.5V supply range, making it suitable for both battery-powered and line-powered systems. Its low-power consumption is further enhanced by multiple power-saving modes, including Sleep mode, which drastically reduces power draw when the CPU is idle.

With its comprehensive feature set and proven reliability, the PIC16F871-I/P serves as a versatile solution for designers seeking a capable and cost-effective 8-bit microcontroller.
