The PIC16F72 is a 28-pin Flash-based 8-bit CMOS microcontroller from Microchip Technology, a well-established member of the Mid-Range PIC16F family. This general-purpose MCU features the classic Mid-Range PIC architecture with 35 instructions and an 8-level deep hardware stack, offering 3.5KB (2K x 14 words) of Flash program memory and 128 bytes of RAM. It operates at up to 20 MHz with a 200 ns instruction cycle, delivering 5 MIPS of processing power. Key peripherals include a 5-channel 8-bit ADC for analog sensing, a Capture/Compare/PWM (CCP) module for timing and PWM applications, and a Synchronous Serial Port (SSP) supporting SPI and I2C communication. Three timer modules (TMR0, TMR1, TMR2) provide flexible timing and counting functions. The device supports multiple oscillator options including RC, XT, HS, and LP modes, allowing design flexibility for cost or performance optimization. With its 22 I/O pins capable of 25 mA sink/source current, it can directly drive LEDs and other loads. The PIC16F72 is pinout compatible with the legacy PIC16C72/72A and PIC16F872 devices, making it a drop-in upgrade path. Available in PDIP, SOIC, SSOP, and QFN packages with industrial temperature range (-40°C to +85°C) and wide operating voltage (2.0V-5.5V).

The PIC16F72 is based on the Mid-Range PIC RISC architecture with Harvard design, providing separate buses for 14-bit program memory and 8-bit data memory. Most of the 35 instructions execute in a single clock cycle, with an 8-level deep hardware stack supporting subroutine calls and interrupt context saving. The 8-bit ADC uses a successive approximation register (SAR) architecture to convert analog voltages from 5 input channels, with 8-bit resolution and a 0-5V input range relative to VDD. The CCP (Capture/Compare/PWM) module provides three modes: Capture mode captures the time of an external event with 16-bit resolution (12.5 ns max at 20 MHz), Compare mode generates timed output events with 16-bit resolution (200 ns), and PWM mode generates up to 10-bit resolution PWM signals for motor control and LED dimming. The Synchronous Serial Port (SSP) handles both SPI (Master/Slave) and I2C (Slave) communication in hardware, offloading serial protocol processing from the CPU. Three timer modules provide timing functions: Timer0 (8-bit with 8-bit prescaler), Timer1 (16-bit with prescaler and external gate), and Timer2 (8-bit with period register, prescaler, and postscaler), often used as the PWM time base. The Watchdog Timer uses an independent on-chip RC oscillator to provide a system reset if software hangs. Power management includes Sleep mode with low current consumption for battery operation. The Flash program memory supports In-Circuit Serial Programming (ICSP) for field re-programmability.
