Microchip PIC16F1826-I/SS 8-Bit Microcontroller Overview and Application Guide

The PIC16F1826-I/SS from Microchip Technology represents a versatile and highly capable 8-bit microcontroller within the enhanced mid-range PIC16F1xxx family. Housed in a compact 20-SSOP package, this device is engineered for a broad spectrum of embedded control applications, balancing performance, power efficiency, and cost-effectiveness.

At its core, the microcontroller features an enhanced 8-bit RISC architecture with a 32 MHz internal oscillator, enabling a execution speed of up to 8 MIPS. A significant advantage is its extensive set of integrated peripherals, which reduces external component count and simplifies board design. Key peripherals include:

mTouch capacitive sensing module (CPS): Enables the implementation of robust touch interfaces without external components.

Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART): Supports both LIN and DMX protocols for serial communication.

Two I²C/SPI serial interfaces: Facilitates communication with a vast ecosystem of sensors, memories, and other peripherals.

Complementary Waveform Generator (CWG): A powerful module for generating precise, complementary output signals, ideal for motor control and power conversion applications.

7-channel 10-bit Analog-to-Digital Converter (ADC) and comparators for accurate analog signal acquisition and processing.

The device operates from 1.8V to 5.5V, making it suitable for both battery-powered and line-operated systems. Its nanoWatt XLP technology ensures extremely low power consumption in Active, Idle, and Sleep modes, which is critical for portable and remote applications.
