Overview

The PIC16F18346-E/SS is an 8-bit microcontroller from Microchip's eXtreme Low Power (XLP) family, designed specifically for functional safety applications. It features 28KB of Flash memory and 2KB of RAM in a compact 20-SSOP package, operating at speeds up to 32MHz. This MCU integrates Core Independent Peripherals (CIPs) like the Configurable Logic Cell (CLC) and Complementary Waveform Generator (CWG) to handle hardware tasks with minimal CPU intervention.

Why Choose This Part

This MCU offers a balance of memory and peripherals for safety-critical designs, including hardware stack monitoring and a dedicated watchdog oscillator. The integration of 256 bytes of EEPROM allows for robust non-volatile storage of calibration data without consuming Flash space. Its eXtreme Low Power (XLP) modes significantly reduce current draw in standby, making it ideal for energy-sensitive applications.

Applications

Industrial Safety Controllers
Utilizes integrated functional safety features to monitor and manage emergency stop systems or safety interlocks.
Battery-Powered Remote Sensors
Leverages XLP technology and Sleep modes down to 875uA to extend battery life in wireless monitoring nodes.
Automotive Interior Lighting
The CWG and PWM peripherals provide precise control for LED dimming and color mixing in cabin electronics.
Appliance Control Modules
Manages user interfaces and motor logic in white goods using the hardware-based Configurable Logic Cells.

Getting Started

Development is supported by the MPLAB X IDE and the XC8 C Compiler. For rapid prototyping, use the MPLAB Code Configurator (MCC) to graphically initialize the Core Independent Peripherals and functional safety modules. Hardware debugging can be performed using the MPLAB PICkit 4 or Snap in-circuit debuggers connected via the ICSP interface.
