Microchip PIC24FJ64GP202-I/MV: A Comprehensive Technical Overview

The Microchip PIC24FJ64GP202-I/MV stands as a prominent member of the PIC24F general-purpose 16-bit microcontroller family. Engineered for a balance of performance, power efficiency, and peripheral integration, this MCU is tailored for a wide array of embedded applications, from industrial control and automation to consumer electronics and Internet of Things (IoT) edge nodes.

At the core of this device lies a high-performance 16-bit modified Harvard architecture CPU, capable of operating at up to 16 MIPS. This robust processing power is driven by an internal 8 MHz internal oscillator, which can be leveraged with a PLL to achieve the full device speed, reducing external component count and board space. A key feature of its design is its exceptional low-power management. With multiple programmable clock modes and a deep sleep (RAM retention) state consuming minimal current, it is ideally suited for battery-powered or energy-harvesting applications.

The '64' in its part number denotes 64 KB of self-programmable Flash memory, providing ample space for complex application code. This is complemented by 8 KB of RAM, ensuring efficient data handling and algorithm execution. For reliable data storage that must persist without power, the MCU also includes 1 KB of non-volatile Data EEPROM, which can be written to during operation.

A significant strength of the PIC24FJ64GP202 is its rich set of integrated peripherals, designed to interface with sensors, actuators, and communication networks without requiring external components. Key peripherals include:

Communication Interfaces: It features two UART modules, an I²C™ module, and two SPI modules, providing versatile connectivity options for everything of RS-232/485 links to sensor chips and wireless modules.

Timing and Control: The device includes a 16-bit timer/counter and a 32-bit timer. Crucially, it is equipped with 5-channel 16-bit PWM (Pulse Width Modulation) outputs, essential for precise control of motors, LEDs, and power converters.

Analog-to-Digital Conversion: A 10-bit ADC with 10 channels allows the microcontroller to digitize analog signals from a multitude of sensors, making it a complete system control solution.

Hardware Real-Time Clock and Calendar (RTCC): This dedicated peripheral allows for accurate timekeeping, a critical function for data logging, scheduling events, and alarm applications.

The device is offered in a compact 28-pin UQFN (6x6 mm) package (suffix -I/MV), making it suitable for space-constrained designs. The 'I' in the part number signifies an industrial temperature range (-40°C to +85°C), ensuring reliable operation in harsh environments.

ICGOOODFIND: The Microchip PIC24FJ64GP202-I/MV is a highly integrated and power-efficient 16-bit microcontroller. Its compelling combination of substantial Flash memory, low-power operation, a rich peripheral set including multiple communication interfaces and PWM, and a compact form factor makes it an excellent choice for developers seeking a capable and versatile core for their embedded designs.
