At its core, the device features a high-performance 16-bit Modified Harvard Architecture CPU capable of operating at up to 16 MIPS. This processing power is driven by an internal 8 MHz oscillator, which can be leveraged with a PLL to achieve the full rated speed, ensuring efficient execution of control algorithms and data processing tasks.

A standout feature of this microcontroller is its substantial integrated memory. It is equipped with 128 KB of high-endurance Flash program memory and 8 KB of RAM, providing ample space for sophisticated application code and data handling. This memory support is crucial for data-intensive tasks without requiring external components.

The peripheral set of the PIC24FJ128GA704 is exceptionally rich, designed to minimize external part count. It includes:

Multiple Communication Interfaces: It boasts two UARTs, two SPI, and two I2C modules, facilitating seamless communication with a vast array of sensors, memory chips, and other peripherals.

Advanced Analog Capabilities: The integrated 12-bit Analog-to-Digital Converter (ADC) with up to 24 channels allows for precise measurement of analog signals, which is vital for sensor-based systems.

Timing and Control: With five 16-bit timers/counters, including a dedicated real-time clock and calendar (RTCC), the MCU offers precise timing control for event management and scheduling.

Hardware Control: It also includes a 4-channel DMA controller, which offloads data transfer tasks from the CPU, significantly improving overall system efficiency and power consumption.

Housed in a 64-pin TQFP package, the -I/PT variant is specified for the industrial temperature range (-40°C to +85°C), making it suitable for harsh operating environments. Its design emphasizes low-power management, featuring multiple software-selectable power-saving modes (Sleep, Idle, and Doze) to optimize energy consumption in battery-powered applications.

ICGOODFIND: The PIC24FJ128GA704-I/PT is a highly integrated and capable 16-bit microcontroller. Its combination of substantial memory, a comprehensive suite of communication and analog peripherals, and robust low-power features makes it an exceptional choice for developers designing connected, sensor-rich, and power-sensitive embedded systems.
