PIC16F876-I/SP 8-Bit Flash Microcontroller with ADC and USART DIP-28 (PIC16F876-I/SP DIP IC)
The PIC16F876-I/SP is a high-performance, 8-bit Flash-based microcontroller from Microchip's mid-range family, housed in a 28-pin Skinny DIP package. It features a powerful RISC architecture with 35 single-word instructions and achieves 200ns instruction execution at 20MHz. This IC offers 14KB of Flash program memory, 368 bytes of RAM, and 256 bytes of high-endurance EEPROM. It is exceptionally well-equipped with peripherals, including a 5-channel 10-bit Analog-to-Digital Converter (ADC), two Capture/Compare/PWM (CCP) modules, and a Synchronous Serial Port (SSP) supporting SPI and I2C. The inclusion of a hardware USART makes it a robust solution for complex serial communication and mixed-signal processing.
This IC is primarily used in industrial automation, multi-peripheral controllers, and automotive sensor interfaces. It is a highly popular component for Arduino electronics projects in India for building DIY data loggers, advanced motor speed controllers, and smart embedded systems that require substantial program memory and non-volatile data storage in a 28-pin DIP footprint.
