The Microchip PIC16F636T-I/ST is a high-performance, cost-effective 8-bit microcontroller from Microchip’s extensive PIC® MCU portfolio. Built on an enhanced mid-range core with a 2-stage instruction pipeline, this device offers an optimal blend of processing capability, peripheral integration, and power efficiency, making it a versatile solution for a wide range of embedded control applications.

A deep dive into its datasheet reveals a robust architecture centered around a RISC-based CPU operating at up to 20 MHz, delivering a performance of 5 MIPS. The device features 3.5 KB of Flash program memory, 128 bytes of RAM, and 256 bytes of EEPROM data memory, providing ample space for both code and critical data storage. A key strength of the PIC16F636 lies in its rich set of integrated peripherals. These include:

Analog-to-Digital Converter (ADC): A 10-bit ADC with up to 8 channels, enabling precise measurement of analog sensors and signals.

Timers: Multiple timers (Timer0, Timer1, Timer2) for a variety of timing, counting, and PWM generation tasks.

Comparators: Two analog comparators with programmable reference voltage (CVREF), useful for simplifying analog signal conditioning without external components.

Enhanced Capture/Compare/PWM (ECCP) Module: Provides advanced PWM functionality for controlling motors, LEDs, and other actuators.

Communication Interfaces: Support for SPI, I2C, and RS-232 protocols via the Master Synchronous Serial Port (MSSP) and an on-board USART module, facilitating communication with other ICs, sensors, and peripherals.

Low-power management is a cornerstone of its design. The PIC16F636T-I/ST features multiple oscillator options and a suite of power-saving modes, including Sleep mode, where power consumption drops to the nanoampere range. This makes it exceptionally well-suited for battery-powered and portable applications where extending operational life is paramount.
