Overview

The PIC16F18326-E/SL is a versatile 8-bit microcontroller from Microchip's eXtreme Low Power (XLP) family, designed specifically for functional safety applications. It operates at up to 32MHz and features Core Independent Peripherals (CIPs) that reduce CPU overhead and power consumption in complex timing and control tasks.

Why Choose This Part

This MCU offers a high memory density for its small 14-SOIC footprint, providing 28KB of Flash and 2KB of RAM. Its 5V tolerance and Core Independent Peripherals allow for robust, deterministic hardware responses without constant CPU intervention, significantly lowering operational power draw.

Applications

Functional Safety Controllers
Utilizes integrated hardware features like the Windowed Watchdog Timer (WWDT) and Cyclic Redundancy Check (CRC) with memory scan for safety-critical monitoring.
Battery-Powered IoT Nodes
Leverages XLP technology to achieve sleep currents as low as 400nA, extending battery life in remote sensing applications.
Industrial Sensor Interfaces
Uses 12 I/O pins and integrated I2C, SPI, and UART to interface with multiple digital sensors in space-constrained industrial housings.
