Microchip PIC16F913-I/SO 8-Bit Microcontroller: Datasheet and Application Overview

The Microchip PIC16F913-I/SO is a versatile 8-bit microcontroller unit (MCU) from the renowned PIC16F family, engineered to deliver a powerful blend of performance, peripheral integration, and cost-effectiveness. Housed in a 28-pin SOIC (Small Outline Integrated Circuit) package, this device is designed for a wide array of embedded control applications, from consumer electronics to industrial automation.

At its core, the PIC16F913 operates using an enhanced mid-range Harvard architecture with a 35-instruction set, enabling concise and efficient code execution. It features a maximum operating frequency of 20 MHz, providing a balanced mix of processing speed and power consumption. The MCU includes 7 KB of Flash program memory and 256 bytes of RAM, ensuring ample space for complex firmware while supporting in-circuit serial programming (ICSP) for easy code updates and debugging.

A standout feature of this microcontroller is its rich set of integrated peripherals. It is particularly well-suited for human-machine interface (HMI) applications due to its integrated LCD driver module, capable of directly driving up to 96 segments. This eliminates the need for an external display driver IC, reducing both system cost and board complexity. Additional key peripherals include:

Analog-to-Digital Converter (ADC): A 10-bit ADC with up to 12 channels for precise sensor data acquisition.

Timers/CCP Modules: Multiple timers (Timer0, Timer1, Timer2) and Capture/Compare/PWM (CCP) modules for generating precise timing signals and controlling motor speeds.

Communication Interfaces: Both EUSART (Enhanced Universal Synchronous Asynchronous Receiver Transmitter) and MSSP (Master Synchronous Serial Port) modules support standard communication protocols like SPI and I²C, facilitating easy connection to sensors, memory chips, and other peripherals.

Comparator: An analog comparator for simplifying external voltage monitoring and threshold detection tasks.

The device also incorporates nanowatt technology, enabling extremely low power consumption through multiple selectable clock modes and a rapid wake-up from sleep mode, making it ideal for battery-powered portable applications.

Application Overview

The PIC16F913-I/SO finds its strength in numerous applications.
