Overview

The PIC16F18344-I/P is an 8-bit microcontroller from Microchip's eXtreme Low Power (XLP) family, featuring 7KB of Flash memory and a 32MHz clock speed. It is designed for functional safety applications and includes Peripheral Pin Select (PPS) for flexible I/O mapping. The 20-pin PDIP package makes it ideal for prototyping and through-hole industrial applications.

Why Choose This Part

This MCU offers a high degree of peripheral flexibility through PPS, allowing engineers to route digital signals to any I/O pin. Its extremely low power consumption in sleep and idle modes is a significant advantage for energy-sensitive designs, while the 5V tolerance on I/O pins simplifies interfacing with older logic levels.

Applications

Industrial Safety Systems
Utilizes integrated functional safety features like Windowed Watchdog Timer and Brown-out Reset for reliable system monitoring.
Battery-Powered Handheld Devices
Leverages XLP technology with typical sleep currents as low as 40nA to extend operating life in portable electronics.
Sensor Interface Nodes
Uses the 17-channel ADC and PPS to interface with multiple analog sensors while maintaining a small footprint.
Legacy System Maintenance
Provides a modern, low-power replacement for older 8-bit PICs in existing through-hole PCB designs.
