PIC24FJ16GA002-E/ML 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, programmable I/O, and a mix of peripherals such as timers, ADC, communication interfaces, and analog comparators. The PIC24F family sits in Microchip's 16-bit MCU portfolio between the 8-bit PIC16/PIC18 and the 32-bit PIC32MX, targeting applications that need more compute and memory than 8-bit parts but lower power and cost than 32-bit ARM Cortex-M devices. The "FJ" prefix denotes the nanoWatt XLP energy-efficient variants.
Key features of this part include a 16 MIPS CPU with single-cycle execution, a 10-bit ADC with up to 500 ksps conversion rate, multiple 16-bit timers, two UART, two SPI and one I2C peripheral, a real-time clock and calendar, an RTCC for calendar/event counting, and a 16-bit Parallel Master Port on 28-pin variants. The 16 KB Flash holds roughly 5.5K instruction words (24-bit each), and code protection plus ICSP (in-circuit serial programming) support in-system firmware updates.
The device uses the PIC24 modified Harvard architecture with separate program and data buses, a deterministic instruction pipeline, and a C-optimized instruction set. The on-chip 8 MHz internal RC oscillator can be combined with the 96 MHz PLL to reach 32 MHz CPU clock, giving the part its headline MIPS rating.
Typical applications include portable instrumentation, sensor conditioning front-ends, low-power IoT sensor nodes, USB/HID peripherals, industrial control panels, and automotive body modules (the -E/ML variant carries the automotive recommended designation and is built on Microchip's AEC-Q100 process flow). The 28-QFN is favored where a compact 6x6 mm PCB footprint and good thermal performance are required.
When designing with this part, place a 1 uF decoupling capacitor within 5 mm of each VDD/VSS pair and route the analog supply (AVDD) through a ferrite bead from VDD. Always keep the MCLR pin pulled high through a 10 kohm resistor and reserve a dedicated ICSP connector for production programming.

主な用途
PIC24FJ16GA002-E/ML の用途: 6 件s: Portable Sensor Conditioning & IoT Edge Nodes, Industrial Control Panels & HMI Keypads, USB/HID Peripheral and PC Accessories, Automotive Body Modules and Lighting, Low-Cost Data Acquisition Front-End, Smart Energy and Sub-metering Devices.
Portable Sensor Conditioning & IoT Edge Nodes
The PIC24FJ16GA002-E/ML fits portable sensor conditioning and IoT edge nodes because it pairs the nanoWatt XLP Sleep mode (typical current below 1 uA) with a 10-bit ADC and 16 MIPS CPU in a 6x6 mm QFN. In a typical battery-powered wireless sensor node, it runs the RTCC-based wake cycle, samples the on-die temperature or external sensor at 100 ksps, buffers the result in the 4 KB SRAM, and sleeps between transmissions. The 2.0V minimum supply lets designers pull energy directly from a single Li-ion or two alkaline cells without a boost converter.
おすすめ
Industrial Control Panels & HMI Keypads
In industrial control panels and HMI keypads, the PIC24FJ16GA002-E/ML provides enough compute for matrix keypad scanning, debouncing, and small LCD/OLED character displays while staying under 50 mA active consumption. The five 16-bit timers drive PWM keypad backlight and buzzer tones, while the UART links to a main controller and the I2C/SPI drives a 128x64 OLED. The automotive -40C to +125C temperature range keeps the design robust for factory floor and outdoor enclosures, and the 28-QFN gives the layout the 6x6 mm footprint needed behind the keypad PCB.
おすすめ
USB/HID Peripheral and PC Accessories
For USB/HID peripherals and PC accessories, the PIC24FJ16GA002-E/ML is supported by Microchip's USB stack and HID library running on the device's internal FS-USB transceiver. A 32 MHz system clock is exactly the multiple of 1.5 MHz required for full-speed USB without an external crystal, and the 16 MIPS CPU handles HID reports at the 1 kHz polling rate without timing overruns. The 16 KB Flash is enough for composite HID + CDC firmware, while the 28-QFN keeps the PCB under 20x20 mm.
おすすめ
Automotive Body Modules and Lighting
The PIC24FJ16GA002-E/ML is Microchip-recommended for automotive designs and operates from -40C to +125C, making it appropriate for body modules such as interior lighting, mirror controllers, and seat control. Its hardware 17x17 multiplier and 16 MIPS throughput can run LED dimming curves, fault detection, and LIN-bus stack time-slicing. The 28-QFN exposed pad gives the thermal margin needed for sealed lamp housings, and the automotive -E suffix keeps the PPAP and traceability aligned with OEM expectations.
おすすめ
Low-Cost Data Acquisition Front-End
As a low-cost data acquisition front-end, the PIC24FJ16GA002-E/ML combines a 10-bit ADC with up to 10 channels and 500 ksps sample rate, five 16-bit timers for precise pacing, and UART/SPI for backhaul. The 4 KB SRAM buffers a 1 ksample waveform between transmissions, and the 2.0V-3.6V supply lets the board take power from a regulated USB or a 3.3V LDO. The small 28-QFN footprint keeps the analog front-end PCB below 25x25 mm, ideal for portable test equipment and educational instrumentation.
おすすめ
Smart Energy and Sub-metering Devices
For smart energy and sub-metering devices, the PIC24FJ16GA002-E/ML is the low-power supervisory MCU that drives the LCD, samples the metrology front-end, and manages the UART/IrDA link to the concentrator. Sleep currents below 1 uA keep battery backups alive for years, while the RTCC handles time-of-use tariffs and tamper logging. The automotive-grade temperature range helps the design survive outdoor meter enclosures, and the 28-QFN gives layout engineers a compact power-quality module.

設計ノート
Decouple each VDD/VSS pair with a 100 nF X7R ceramic placed within 5 mm of the pin, and add a single 10 uF bulk capacitor at the board's MCU supply origin. For the analog supply, route AVDD through a ferrite bead from VDD and place a second 100 nF + 10 uF pair at the analog pins. This topology keeps the on-chip ADC below 1 LSB noise at 500 ksps sampling rates. Estimated: input current at 32 MHz with all peripherals active is roughly 25 mA per the family datasheet DC characteristics, leaving ~15 mA of analog headroom.
The 28-QFN ML package exposes a thermal pad underneath the IC that must be soldered to the PCB ground plane. Stencil an array of 0.3 mm vias in the pad region to drop thermal resistance to below 20 C/W and to give the ADC's VSS reference a low-impedance return. Keep the analog traces (OSC, ADC, comparators) routed on the opposite layer from the digital switching signals, with a continuous ground pour underneath the IC for RF immunity.
Always tie MCLR through a 10 kohm pull-up to VDD and provide a 100 nF cap to VSS to ensure proper reset behaviour; floating MCLR is the most common cause of 'unprogrammed' boards. Reserve the PGD/PGC pins (RB0/RB1) for ICSP - do not multiplex them with high-frequency signals or place them more than 50 mm from the programming connector. Finally, when configuring the 96 MHz PLL, set the OSCTUN and PLL postscaler correctly or the device will lock up at 32 MHz core while peripherals run at the wrong rate.
Estimated: at 32 MHz, 3.3V, and all peripherals active, the PIC24FJ16GA002-E/ML dissipates about 80 mW. With the QFN thermal pad soldered to a 1 square inch 1-oz copper pour on a 4-layer board, theta_JA is roughly 25 C/W, so the junction rise is ~2 C above ambient. In sealed enclosures without airflow, derate the active current budget or add 2 square inches of copper to keep Tj well below the +125C limit.
