Microchip PIC16F74-I/P 8-Bit Microcontroller Overview and Application Guide
The Microchip PIC16F74-I/P is a high-performance 8-bit microcontroller from Microchip Technology’s extensive PIC® MCU family. Built on an enhanced Flash-based CMOS architecture, this device combines a powerful RISC CPU with versatile peripherals, making it a reliable and cost-effective solution for a wide array of embedded control applications. Housed in a 40-pin PDIP package, it is well-suited for prototyping, educational purposes, and industrial systems.
At its core, the PIC16F74 features a 8-bit RISC CPU that executes instructions at a clock speed of up to 20 MHz, delivering a throughput of up to 5 MIPS. This ensures efficient and speedy processing for real-time control tasks. It contains 7 KB of Flash program memory, which is reprogrammable, allowing for significant flexibility during development and field updates. With 192 bytes of RAM and 128 bytes of EEPROM data memory, it offers ample space for data storage and variable handling in complex applications.
A key strength of this microcontroller lies in its rich set of integrated peripherals. It includes multiple timing resources, including three timers/counters (Timer0, Timer1, and Timer2), which are essential for tasks like event counting, interval timing, and PWM generation. For analog interfacing, it is equipped with an 8-channel 8-bit Analog-to-Digital Converter (ADC), enabling the system to read values from sensors monitoring temperature, pressure, or voltage.
Communication is facilitated through both Serial Peripheral Interface (SPI) and Inter-Integrated Circuit (I²C) modules, allowing for seamless data exchange with other peripherals like memory chips, sensors, and display drivers. Furthermore, it features a Universal Synchronous Asynchronous Receiver Transmitter (USART) for serial communication with PCs or other modules.
The PIC16F74-I/P is designed for robust operation across industrial temperature ranges (-40°C to +85°C) and features high sink/source current capabilities on its I/O pins, allowing it to drive LEDs and relays directly. Its low power consumption modes, including SLEEP, make it ideal for battery-powered applications.
