The Microchip PIC16LF18854-E/SO is an 8-bit MCU with a PIC core running at 32MHz. It provides 7KB flash and 512 x 8 RAM in a 28-SOIC package. Operating from 1.8V to 3.6V, it includes Brown-out Detect/Reset, POR, PWM, and WDT. This low-power MCU is designed for battery-operated and industrial applications requiring extended temperature range.

  • Ultra-low voltage operation (1.8V) extends battery life in portable designs.
  • Wide temperature range (-40°C to 125°C) suits harsh industrial environments.
  • Integrated Brown-out Reset and WDT enhance system reliability.
  • 28-SOIC package is industry-standard and easy to solder.

Battery-Powered IoT Sensors

The 1.8V-3.6V range allows direct CR2032 coin cell operation, while 32MHz speed enables fast sensor sampling and BLE communication.

Portable Medical Devices

Low voltage and 125°C rating support wearable health monitors, with PWM for haptic feedback and WDT for fail-safe operation.

Smart Home Thermostats

With 7KB flash, it handles temperature sensing and LCD control, while Brown-out Reset ensures reliable startup.

Industrial Process Controllers

The -40°C to 125°C range and SOIC package make it suitable for harsh environments, with PWM driving analog outputs.

Consumer Appliance Timers

It can manage wash cycles or oven timers, using WDT to recover from software glitches.

LED Lighting Control

PWM modules allow dimming and color mixing, while low power consumption extends battery life in portable lamps.
