PIC16F73-I/SP 8-Bit Flash Microcontroller with ADC and USART DIP-28 (PIC16F73-I/SP DIP IC)
The PIC16F73-I/SP is a high-performance, 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 a 5-channel 8-bit Analog-to-Digital Converter (ADC), two Capture/Compare/PWM (CCP) modules, and a Synchronous Serial Port (SSP) for SPI/I2C. Additionally, it includes a Universal Synchronous Asynchronous Receiver Transmitter (USART) for robust serial communication.
This IC is primarily used in industrial automation, serial-to-parallel converters, and automotive control systems. It is a popular choice for Arduino electronics projects in India for building DIY wireless data links, multi-peripheral controllers, and advanced embedded systems that require hardware-based serial communication (UART) in a 28-pin Skinny DIP package.
