PIC16F72-I/SP 8-Bit Flash Microcontroller with ADC DIP-28 (PIC16F72-I/SP DIP IC) The PIC16F72-I/SP is a high-performance, 8-bit Flash-based microcontroller from Microchip, designed to provide a powerful yet cost-effective solution for mid-range control applications. It features a RISC architecture with only 35 single-word instructions and achieves a fast 200ns instruction execution speed at 20MHz. This IC includes 3.5KB of Flash program memory and 128 bytes of RAM. A standout feature is its integrated 5-channel 8-bit Analog-to-Digital Converter (ADC), along with a Capture/Compare/PWM (CCP) module and a versatile Synchronous Serial Port (SSP) that can be configured for SPI or I2C communication.
This IC is primarily used in industrial control systems, automotive sensors, and household appliances. It is a highly popular component for Arduino electronics projects in India for building multi-channel data acquisition systems, high-speed PWM motor controllers, and smart embedded devices that require reliable serial communication in a standard 28-pin DIP package.
