Overview

The PIC16F18345-I/P is a versatile 8-bit microcontroller featuring 14KB of Flash memory and a rich set of Core Independent Peripherals (CIPs) in a hobbyist-friendly 20-pin PDIP package. Operating at up to 32MHz, it includes Peripheral Pin Select (PPS) which allows for flexible I/O mapping of digital peripherals to any GPIO pin.

Why Choose This Part

This MCU offers a high ratio of features to pin count, including 1KB of RAM and hardware-based peripherals that operate independently of the core to reduce CPU overhead. The wide operating voltage range up to 5.5V and the inclusion of dedicated EEPROM provide robust data retention for small-scale industrial applications.

Applications

Industrial Sensor Interfaces
Utilize the 256 bytes of EEPROM and integrated I2C/SPI interfaces to calibrate and communicate with environmental sensors.
Embedded System Glue Logic
The Peripheral Pin Select (PPS) and configurable logic cells make it an ideal candidate for signal routing and basic hardware logic replacement.
Educational and Prototyping Projects
The PDIP-20 package fits directly into standard breadboards and sockets, making it perfect for teaching embedded RISC architecture.
