Overview

The PIC24FJ256GA110-I/PT is a high-density 16-bit microcontroller from Microchip's PIC24F family, featuring 256KB of Flash memory and 16KB of RAM. Operating at speeds up to 32MHz (16 MIPS), it provides an expansive 100-pin TQFP package with 85 I/O pins for complex system integration. The device includes a rich peripheral set including four UARTs, three SPI ports, and three I2C ports, making it suitable for communication-heavy applications.

Why Choose This Part

The part offers a high pin-to-performance ratio, providing 85 I/O pins and extensive serial connectivity without the complexity of a 32-bit architecture. It supports 5.5V tolerant digital inputs which simplifies interfacing with legacy 5V logic systems while running on a modern 2.0V to 3.6V supply. Integrated DMA channels and a hardware CRC engine further offload the CPU, enhancing real-time responsiveness in communication tasks.

Applications

Industrial Protocol Bridges
Utilizing four UARTs and three SPI/I2C interfaces to bridge data between different industrial communication standards.
User Interface Controllers
Leveraging the Parallel Master Port (PMP) to drive character or graphic LCDs while managing multiple tactile inputs via 85 GPIO pins.
Data Logging Systems
Using the 256KB Flash and integrated hardware CRC for reliable storage and verification of sensor data from the 16-channel 10-bit ADC.
Remote Monitoring
Employing the ultra-low power Sleep and Idle modes alongside the Real-Time Clock (RTC) for scheduled sensor sampling in battery-powered installations.
