The Microchip PIC16F882-I/SP is a versatile 8-bit microcontroller built on PIC® architecture, offering a robust blend of performance, integration, and cost-effectiveness. Housed in a 28-pin SPDIP package, this device is designed for a wide array of embedded control applications, from industrial automation to consumer electronics and automotive systems.

At its core, the microcontroller operates at a maximum frequency of 20 MHz, delivering a performance of 5 MIPS. It features 3.5 KB of Flash program memory and 128 bytes of EEPROM data memory, providing ample space for code and critical data storage that must be retained during power cycles. With 368 bytes of RAM, it efficiently handles data manipulation during runtime.

A key strength of the PIC16F882 lies in its rich set of integrated peripherals. It includes a 10-bit Analog-to-Digital Converter (ADC) with 11 channels, enabling precise measurement of multiple analog signals. For control applications, it offers two comparators and a Capture/Compare/PWM (CCP) module. The Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART) facilitates serial communication (UART), while the Serial Peripheral Interface (SPI) and Inter-Integrated Circuit (I²C) modules support communication with various sensors, memories, and other peripherals.

The device is renowned for its low-power capabilities, featuring a Nanowatt Technology operating mode. This allows the microcontroller to enter various sleep states, drastically reducing power consumption, which is critical for battery-operated applications. Its wide operating voltage range (2.0V to 5.5V) further enhances its suitability for portable and power-sensitive designs.

Development is supported by Microchip’s comprehensive MPLAB X IDE and the MPLAB XC8 compiler, allowing for efficient code development and debugging. The availability of a In-Circuit Serial Programming (ICSP)™ interface enables easy and fast firmware updates directly on the target board.
