Microchip PIC24FJ256GA110-I/PT: A Comprehensive Technical Overview

The Microchip PIC24FJ256GA110-I/PT stands as a prominent member of the PIC24F family, representing a robust 16-bit architecture engineered for applications demanding high performance, connectivity, and low power consumption. This microcontroller unit (MCU) is particularly suited for complex embedded systems in industrial, medical, and consumer markets. This overview delves into its core technical specifications, key features, and potential applications.

At the heart of this MCU lies a high-performance 16-bit modified Harvard architecture with an enhanced instruction set. The core operates at a maximum frequency of 16 MIPS (16 MHz), providing a solid balance between processing power and energy efficiency. A significant feature is its 256 KB of self-programmable Flash memory and 16 KB of RAM, offering ample space for sophisticated application code and data handling. The inclusion of Dual Partition Flash with Live Update capability allows for secure field firmware updates, a critical feature for maintaining and upgrading deployed devices without downtime.

Connectivity is a major strength of the PIC24FJ256GA110. It is equipped with a rich set of peripherals designed to interface with a wide array of sensors, actuators, and communication networks. Key communication interfaces include:

Multiple Serial Channels: It features two UARTs, two SPI, and two I²C™ modules, facilitating easy connection to peripherals like sensors, displays, and memory chips.

USB 2.0 On-The-Go (OTG): The integrated USB module allows the device to act as either a host or a peripheral, enabling communication with a vast ecosystem of USB devices.

CAN Module: The Controller Area Network (CAN) 2.0b interface is essential for robust and reliable communication in automotive and industrial network applications.

For analog interfacing and control, the MCU integrates a 10-bit Analog-to-Digital Converter (ADC) with up to 16 channels, capable of 500 ksps sampling, and three operational amplifiers for signal conditioning. Control is managed through five 16-bit timers/counters and a hardware Real-Time Clock and Calendar (RTCC), providing precise timing capabilities. Furthermore, it supports motor control with peripheral pin select (PPS) functionality, which allows for flexible remapping of digital pins to optimize board layout.

Packaged in a 100-pin TQFP, this device offers extensive I/O capabilities. It is characterized for industrial temperature ranges (-40°C to +85°C), ensuring reliable operation in harsh environments. Its design emphasizes low power consumption, featuring multiple power-saving modes (Sleep, Idle, and Doze) to extend battery life in portable applications.

ICGOOODFIND: The PIC24FJ256GA110-I/PT is a highly integrated and versatile 16-bit microcontroller. Its combination of substantial memory, extensive peripheral set (including USB OTG and CAN), and robust industrial features makes it an excellent choice for developers building connected, real-time, and power-sensitive embedded systems that require reliable performance and future-proof field upgrade capabilities.
