PIC24FJ16GA002-I/ML - 16KB Flash 16-bit MCU 28-QFN | Microchip
MPN: PIC24FJ16GA002-I/ML ✓ Hoạt độngPIC24FJ16GA002-I/ML Tóm tắt
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.

Ghi chú thiết kế
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.
Thông tin tuân thủ
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.
