Overview

The PIC16LF18345-I/SS is a low-power 8-bit microcontroller from Microchip featuring XLP (eXtreme Low Power) technology and 14KB of Flash memory. Operating at up to 32MHz, it integrates Core Independent Peripherals such as Configurable Logic Cells (CLC) and Complementary Waveform Generators (CWG) to handle hardware tasks with minimal CPU intervention.

Why Choose This Part

This MCU offers an excellent balance of 18 I/O pins in a compact 20-pin SSOP package, making it suitable for space-constrained designs. Its Core Independent Peripherals (CIPs) reduce system power consumption by allowing the CPU to remain in low-power modes while performing complex timing and logic functions.

Applications

Battery-Powered Remote Sensors
Utilizes XLP technology and a 40uA sleep current to extend the life of coin-cell operated wireless nodes.
Handheld Medical Devices
Ideal for portable diagnostics where small SSOP packaging and low standby power consumption are critical.
Industrial Logic Controllers
The integrated Configurable Logic Cells allow for hardware-based signal processing and custom glue logic without software overhead.
Motor Control Signalling
Leverages the Complementary Waveform Generator (CWG) for dead-band control in half-bridge and full-bridge drive topologies.

Getting Started

Developers should use the MPLAB X IDE and the XC8 Compiler for firmware development. Hardware debugging is best performed using the MPLAB PICkit 4 or Snap in-circuit debugger, while the MPLAB Code Configurator (MCC) plugin simplifies the setup of the internal oscillators and peripherals.
