Microchip PIC16F628-04/P 8-Bit Microcontroller Overview

The PIC16F628-04/P is a versatile 8-bit microcontroller from Microchip Technology, designed for a wide range of embedded control applications. Fabricated with CMOS technology, this device combines high performance, low power consumption, and a rich set of peripheral features in an 18-pin PDIP package.

At its core lies a RISC-based CPU operating at a maximum frequency of 4 MHz (indicated by the -04 speed grade), capable of executing most instructions in a single cycle. This efficiency ensures responsive performance for time-critical tasks. The microcontroller is equipped with 2 KB of Flash program memory, 224 bytes of RAM, and 128 bytes of EEPROM data memory, providing ample space for both code and non-volatile data storage.

A key feature of the PIC16F628A is its robust set of integrated peripherals. These include two analog comparators, a programmable 16-bit timer (Timer1) with oscillator options, a second 8-bit timer, and a PWM (Pulse Width Modulation) module for precise motor control or power regulation. It also supports serial communication via a USART (Universal Synchronous Asynchronous Receiver Transmitter) module, enabling both UART and SPI/I²C protocols. Furthermore, its brown-out reset (BOR) and watchdog timer (WDT) enhance system reliability in electrically noisy environments.

Notably, this model features an internal 4 MHz oscillator, allowing it to operate without an external crystal, which simplifies circuit design and reduces both component count and cost. Its wide operating voltage range (2.0V to 5.5V) and low power consumption make it exceptionally well-suited for battery-powered and portable devices.
