PIC24FJ16GA002-I/ML Übersicht
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, I/O peripherals, and interrupt logic onto one die. The PIC24F family specifically uses Microchip's 16-bit enhanced RISC architecture and is positioned in the mid-range performance tier between 8-bit PIC MCUs and 32-bit PIC32 devices. Within Microchip's hierarchy, this part sits in the PIC24F eXtreme Low Power sub-family, which targets battery-powered and energy-sensitive embedded designs where dynamic power consumption must be minimized without sacrificing compute throughput.
Key features include the eXtreme Low Power (XLP) sleep modes that draw nano-amp-level currents, a 16-channel 10-bit ADC with 500 ksps conversion rate, multiple serial interfaces (UART, SPI, I2C), and four 16-bit timers. The device also supports ICSP (In-Circuit Serial Programming) and JTAG boundary scan for development and manufacturing programming workflows. The 28-QFN package provides a compact 6 mm x 6 mm footprint suitable for space-constrained PCB designs.
The architecture uses a 24-bit instruction word with 16-bit data path, allowing most instructions to execute in one cycle. The hardware multiply/divide unit accelerates DSP-style computations (filtering, FFT, motor control loops) that would otherwise burden software loops, and the peripheral pin select (PPS) feature lets most digital peripherals be remapped to alternate I/O pins, simplifying PCB routing.
Typical applications include industrial sensor interfaces, low-power IoT edge devices, USB human-interface device (HID) controllers, battery-powered data loggers, and consumer white goods. The combination of XLP sleep, integrated ADC, and 16 MIPS throughput makes it well-suited for portable instrumentation that must wake periodically, sample, process, and return to deep sleep.
Design consideration: at 32 MHz with 3.3V supply the core draws roughly 15 mA active and 20 nA in deep sleep, so duty-cycling the CPU is the most effective power-reduction lever. Use the internal 8 MHz oscillator with PLL to keep BOM cost low, but add an external crystal when USB or CAN timing accuracy is required.

The PIC24FJ16GA002-I/ML suits industrial sensor interface boards because its -40C to +85C industrial rating covers factory floor conditions and its 16 MIPS performance handles 4-20 mA loop signal processing, HART protocol bit-banging, and filtering in real time. The 21 I/O pins connect to multiple sensor channels, opto-isolated digital inputs, and relay outputs without external muxing. The Peripheral Pin Select (PPS) feature simplifies PCB routing when I/O assignments change between sensor variants. Robust ESD and EMI performance of the PIC24F family suits electrically noisy industrial cabinets.
Empfohlen
USB Human Interface Device (HID) Controller
The PIC24FJ16GA002-I/ML is appropriate for USB HID peripherals such as custom keyboards, mice, and game controllers because its 16 MIPS core runs the USB 2.0 full-speed stack and HID report handling with sufficient margin. The 4 KB RAM holds HID report buffers and protocol state, while 16 KB Flash accommodates stack plus application logic. The QFN package's compact 6 x 6 mm footprint fits inside USB dongle form factors. Internal 8 MHz oscillator with PLL provides the 48 MHz USB clock required by USB 2.0 FS without external crystal cost.

Consumer White Goods Control Board
The PIC24FJ16GA002-I/ML fits consumer white goods such as washing machines, dishwashers, and microwave oven controllers because its 16 MIPS performance runs motor control algorithms (PWM, PID loops) for brushless DC motors while its 21 I/O pins interface with keypads, displays, and sensors. The 16 KB Flash holds UI logic and safety routines. The PIC24F family's mature ecosystem (MPLAB X IDE, XC16 compiler) accelerates development. QFN package suits the high-density main control boards typical in modern appliances.
Empfohlen
Portable Medical Monitoring Device
The PIC24FJ16GA002-I/ML serves portable medical monitoring devices such as pulse oximeters and glucose meters because its low XLP sleep currents extend battery life while its 16 MIPS performance runs real-time filtering of bioelectric signals. The 10-bit ADC captures analog sensor outputs directly, and the hardware multiplier accelerates DSP-style filters (moving averages, IIR). The 28-QFN compact footprint fits handheld enclosures. Note that this part is not AEC-Q100 qualified for automotive; medical device designers should validate full IEC 60601 compliance at the system level.
Empfohlen
Automotive Body Control Module
The PIC24FJ16GA002-I/ML is recommended for automotive body control applications per Microchip's product page descriptor. Its 16 MIPS core runs CAN/LIN stack tasks and body electronics control logic while industrial -40C to +85C rating covers cabin environments. The 21 I/O pins drive window regulators, mirror controls, and lighting PWM outputs. For under-hood or AEC-Q100 qualified deployments, designers should select the automotive-grade variants in the same PIC24FJ family, as this specific suffix is not AEC-Q100 qualified.

Designhinweise
The PIC24FJ16GA002's XLP sleep modes draw less than 100 nA typical in deep sleep with RTCC running, but active current at 32 MHz and 3.3V is approximately 15 mA. Estimated: duty-cycling 1% active with 99% sleep yields average current of roughly 150 uA - well-suited for coin-cell applications. Use the internal 8 MHz oscillator with PLL for active bursts to avoid external crystal warm-up time.
The 28-QFN (6 x 6 mm) package has an exposed thermal pad that MUST be soldered to a PCB copper pour for mechanical reliability and thermal dissipation, despite this being a low-power MCU. A minimum 1 square inch copper pour on top layer connected to VSS is recommended per Microchip QFN landing pattern guidelines. Decoupling: place 100 nF X7R as close as possible to each VDD/VSS pin pair, plus a bulk 10 uF tantalum or ceramic at the package entry.
Watch the supply voltage range - PIC24FJ parts operate from 2.0V to 3.6V (typical), NOT 5V. Common mistakes include level-shifting mistakes on digital I/O interfacing 5V peripherals directly without a level translator. Also, when migrating from PIC24FJ16GA002 to PIC24FJ32GA002 or higher, verify the ICSP programming pins (PGECx/PGEDx) match your programmer's pinout - some PIC24F variants remap these pins.
The 10-bit ADC achieves 500 ksps but accuracy degrades above 200 ksps due to input impedance and acquisition timing. For high-impedance sources (>5 kohm), add an external op-amp buffer or use the PIC24F's internal ADC channel with longer acquisition time. Route analog traces away from digital switching signals and use a separate analog ground island connected to digital ground at a single point near the MCU's AVSS pin.
Compliance-Informationen
RoHS compliant per Microchip product page. Not AEC-Q100 qualified; recommended for automotive design but automotive-grade qualification requires -VAO suffix parts. PIC24FJ16GA002 is recommended for automotive design applications per Microchip's product descriptor, but standard -I/ML is industrial temp grade.
