About this item

The PIC16F84A is one of the most popular and widely used 8-bit microcontrollers from Microchip Technology’s PIC family. It is known for its simplicity, reliability, and versatility, making it an excellent choice for beginners and professionals alike in embedded system development and learning environments. The microcontroller is based on Harvard architecture with RISC (Reduced Instruction Set Computing), enabling it to execute instructions efficiently and quickly. The PIC16F84A features 1K words of Flash memory for program storage, allowing users to write and modify code multiple times. It also includes 64 bytes of RAM for data storage and 64 bytes of EEPROM for non-volatile data retention, making it suitable for applications requiring data retention without continuous power. It has 13 general-purpose input/output pins (I/O) with configurable options and supports interrupts for responsive control. One of its main attractions is the availability of an internal timer/counter and a watchdog timer that helps improve the reliability of applications by resetting the system during faults. Its low power consumption and support for sleep modes make it a good fit for battery-powered projects. Due to its ease of programming, compatibility with MPLAB IDE, and moderate features, the PIC16F84A remains a go-to microcontroller for simple control systems, hobby projects, and educational purposes.
