PIC16F74-I/P 8-Bit Flash Microcontroller with ADC and USART DIP-40 (PIC16F74-I/P DIP IC)
The PIC16F74-I/P is a high-performance, 40-pin 8-bit Flash-based microcontroller from Microchip's mid-range family. It features a powerful RISC architecture with 35 single-word instructions and achieves a fast 200ns instruction execution at 20MHz. This IC offers 7KB of Flash program memory and 192 bytes of RAM. It is highly versatile, featuring an 8-channel 8-bit Analog-to-Digital Converter (ADC), two Capture/Compare/PWM (CCP) modules, and a Universal Synchronous Asynchronous Receiver Transmitter (USART/UART) for robust serial communication. With 33 I/O pins, it provides extensive connectivity for complex system designs in a standard 40-pin DIP package.
This IC is primarily used in industrial automation, multi-sensor monitoring systems, and automotive control units. It is a popular choice for Arduino electronics projects in India for building DIY smart home hubs, multi-peripheral controllers, and advanced embedded systems that require a high number of I/O pins and hardware-based serial communication (UART).
