Microchip PIC24FJ128GA310-I/PT: A Comprehensive Technical Overview

The Microchip PIC24FJ128GA310-I/PT represents a high-performance, 16-bit microcontroller within the expansive PIC24F family. Engineered for demanding embedded applications, this device combines robust processing power with a rich set of integrated peripherals, making it a versatile solution for complex control tasks in industrial, medical, and consumer markets.

At its core lies a powerful 16-bit modified Harvard architecture CPU, capable of operating at speeds up to 16 MIPS. This ensures efficient execution of control algorithms and data processing routines. The device is equipped with 128 KB of self-programmable Flash memory and 8 KB of RAM, providing ample space for application code and data handling. A key feature enhancing its reliability is the Direct Memory Access (DMA) controller, which supports five channels. This allows for peripheral-to-memory data transfers without CPU intervention, significantly reducing overhead and improving overall system efficiency.

The peripheral set of the PIC24FJ128GA310 is exceptionally comprehensive. It includes multiple communication interfaces such as three UARTs, two SPI, and two I2C modules, facilitating seamless connectivity with a wide array of sensors, displays, and other ICs. For analog needs, it integrates a high-speed 10-bit Analog-to-Digital Converter (ADC) with up to 16 channels, capable of 1.1 Msps sampling, which is critical for precise real-time signal acquisition. Furthermore, it features five 16-bit timers/counters and a hardware Real-Time Clock and Calendar (RTCC), essential for time-critical applications and event scheduling.

The inclusion of a USB 2.0 Full-Speed On-The-Go (OTG) module is a standout capability, enabling the device to act as either a host or a peripheral. This makes it ideal for applications requiring communication with USB devices like thumb drives or keyboards. The microcontroller operates from a wide voltage range of 2.0V to 3.6V and is specified for an industrial temperature range of -40°C to +85°C, ensuring stable performance in harsh environments. Housed in a 64-pin TQFP package, it offers a compact footprint with a high number of I/O pins for extensive system interconnectivity.
