PIC16F887-I/P 8-Bit Flash Microcontroller with 14-Channel ADC DIP-40 (PIC16F887-I/P DIP IC)
The PIC16F887-I/P is a flagship 8-bit Flash-based microcontroller from Microchip's enhanced mid-range series (PIC16F88x). Housed in a standard 40-pin DIP package, it is designed to be the modern, feature-rich successor to the classic PIC16F877A. It features a powerful RISC architecture with 35 single-word instructions and offers 14KB of Flash program memory, 368 bytes of RAM, and 256 bytes of high-endurance EEPROM. Key hardware upgrades include a 14-channel 10-bit Analog-to-Digital Converter (ADC), dual Enhanced Capture/Compare/PWM (ECCP) modules, and a precision internal oscillator (up to 8MHz). With its high I/O count, advanced NanoWatt power-saving technology, and versatile communication interfaces, it is a premier choice for complex, high-performance embedded systems.
This IC is the preferred choice for professional prototyping and engineering education in India. It is a highly popular component for Arduino-style electronics projects for building DIY industrial automation controllers, complex robotics, multi-sensor smart home hubs, and advanced solar power management systems that require a high pin count and precise analog sensing in a 40-pin DIP footprint.
