Microchip PIC16F1933-I/SO 8-Bit Microcontroller Technical Overview and Application Guide

The Microchip PIC16F1933-I/SO is a high-performance 8-bit microcontroller built on an enhanced mid-range core with a deep hardware stack and versatile peripheral integration. Housed in a 28-pin SOIC (Small Outline Integrated Circuit) package, this device is engineered for a wide array of embedded control applications, offering a compelling blend of processing capability, power efficiency, and cost-effectiveness.

At its heart, the controller features a robust 8-bit RISC CPU operating at up to 32 MHz, delivering a performance of 8 MIPS. A significant architectural advantage is its nanowatt XLP (eXtreme Low Power) technology, making it exceptionally suited for battery-powered and energy-sensitive applications. The core is supported by 14 KB of self-read/write capable Flash program memory, 512 bytes of data EEPROM, and 1024 bytes of SRAM, providing ample space for both code and data storage.

The peripheral set of the PIC16F1933 is notably rich. It includes:

Enhanced Capture/Compare/PWM (ECCP) modules for sophisticated motor control and power conversion applications.

Multiple communication interfaces: EUSART (for RS-232/485), SPI, and I²C (MSSP) for seamless connection to sensors, memory, and other peripherals.

A 10-bit Analog-to-Digital Converter (ADC) with up to 14 channels, enabling precise measurement of multiple analog signals.

Two comparators and a voltage reference module for analog signal conditioning without external components.

Hardware Timer modules, including an 8-bit and two 16-bit timers, providing flexible timing and counting operations.

Development is streamlined by Microchip’s MPLAB X IDE and the freely available MPLAB XC8 compiler. The microcontroller is also supported by a vast ecosystem of hardware tools, such as the PICkit™ debugger, allowing for rapid prototyping and debugging.
