Microchip PIC16F1936-I/SO 8-Bit Microcontroller Datasheet and Application Overview
The Microchip PIC16F1936-I/SO is a powerful and versatile 8-bit microcontroller (MCU) from Microchip Technology's extensive PIC16F family. Housed in a 28-pin SOIC (Small Outline Integrated Circuit) package, this device is engineered for a wide array of embedded control applications, balancing performance, power efficiency, and cost-effectiveness.
At its core, the PIC16F1936 leverages an enhanced mid-range architecture with a robust 8-bit RISC CPU. It operates at a maximum frequency of 32 MHz, delivering a performance of 8 MIPS. A key feature of this MCU is its nanowatt XLP (eXtreme Low Power) technology, making it exceptionally suited for battery-powered and energy-sensitive applications where minimizing power consumption is paramount.
The memory configuration is substantial for its class, featuring 14 KB of self-read/write Flash program memory and 512 bytes of data EEPROM, which provide excellent flexibility for data storage and parameter retention. It is also supported by 768 bytes of SRAM. The integrated mCal™ peripheral set significantly enhances its functionality without requiring external components. Key peripherals include:
Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART) for serial communication (UART, LIN).
Master Synchronous Serial Port (MSSP) module supporting both SPI and I²C protocols.
Two Capture/Compare/PWM (CCP) modules and one Enhanced CCP (ECCP) for precise motor control and signal generation.
Analog-to-Digital Converter (ADC) with 11 channels and 10-bit resolution.
Two comparators and a fixed voltage reference (FVR) for advanced analog signal conditioning.
Development and debugging are streamlined through its integrated debugger (In-Circuit Debugger - ICD) and a hardware debug interface, allowing for easy programming and real-time troubleshooting. The MCU's operational voltage ranges from 2.0V to 5.5V, supporting direct interaction with a broad spectrum of components.
