PIC24FJ16GA004-E/ML - 16-bit 32MHz MCU 16KB Flash 44-QFN | Microchip
MPN: PIC24FJ16GA004-E/ML ✓ פעילPIC24FJ16GA004-E/ML סקירה
A microcontroller (MCU) is a single-chip computer containing a CPU core, Flash program memory, SRAM data memory, and a rich set of on-chip peripherals such as timers, UARTs, SPI/I2C, ADC, and PWM. The PIC24F family is positioned in Microchip's 16-bit portfolio above the 8-bit PIC16/PIC18 and below the dsPIC and 32-bit PIC32 families; it targets cost-sensitive embedded applications that need more computational headroom and richer peripherals than 8-bit parts can deliver without migrating to 32-bit.
Key features include 16 MIPS throughput at 32 MHz, two UART/SPI/I2C modules, three 16-bit timers, a 10-bit ADC with up to 13 channels, two analog comparators, real-time clock calendar (RTCC) with on-chip calibration, and CTMU (Charge Time Measurement Unit) support for capacitive touch. The 44-QFN (8x8) exposed-pad package gives a compact 8 mm square footprint with an EP that must be soldered for proper thermal dissipation.
The PIC24FJ16GA004 uses a Harvard-architecture CPU with a 16-bit data path and 24-bit instruction word, executed through a modified-RISC pipeline with hardware multiply/divide and zero-overhead looping. The peripheral pin-select (PPS) remapping block allows flexible routing of digital peripherals to physical pins, simplifying PCB layout.
Typical applications include low-power industrial sensing, USB/HID human-interface devices (when paired with the USB-capable PIC24FJ siblings), portable instrumentation, motor control with PWM/feedback, and capacitive-touch front panels using the CTMU. With 4 KB RAM and 16 KB Flash, the device comfortably fits small RTOS kernels or graphical state-machine firmware for sensors, control panels, and consumer appliances.
When designing with the PIC24FJ16GA004-E/ML, the exposed pad of the QFN-44 package MUST be soldered to the PCB ground plane to meet the 31.7 C/W thermal resistance; failing to solder the EP can quickly cause thermal shutdown. Decoupling must follow Microchip's recommended 0.1 uF + bulk capacitor layout within a few millimeters of each power pin.

יישומים טיפוסיים
PIC24FJ16GA004-E/ML מתאים עבור 7 יישוםs: Low-Power Industrial Sensor Hub, Capacitive Touch Front Panel, Portable Medical/Health Monitor, Motor Control with PWM and Feedback, USB/HID Peripheral Adapter (non-USB PIC24F), Consumer Appliance Control Board, Automotive Body / HVAC Module.
Low-Power Industrial Sensor Hub
The PIC24FJ16GA004-E/ML fits industrial sensor hubs because its 16 MIPS core and 35 I/O pins can poll multiple sensors simultaneously while its nanoWatt sleep modes (as low as sub-uA in deep sleep per the Microchip datasheet) keep average power low for battery-backed field installations. With the 10-bit ADC providing up to 13 input channels and the CTMU for capacitive water/leak sensors, a single chip can manage temperature, pressure, level, and humidity. The QFN-44 (8x8) package exposes enough peripheral pins for UART/SPI/I2C to multiple external transducers.
מומלץ
Capacitive Touch Front Panel
The PIC24FJ16GA004-E/ML is well suited for capacitive touch user interfaces because it integrates Microchip's CTMU peripheral that drives mTouch firmware for buttons, sliders, and proximity sensors without an external touch controller. The 35 I/O and PPS remapping let the designer route touch channels across many PCB pads while keeping BOM cost low. The nanoWatt idle mode keeps standby power below 1 mA for wall-powered or PoE appliances, and the extended -40C to +125C rating supports outdoor or kitchen environments.
מומלץ
Portable Medical/Health Monitor
The PIC24FJ16GA004-E/ML is a fit for portable health monitors because the extended -40C to +125C grade and low nanoWatt sleep currents extend battery life for wearables and handheld devices. Its 16 MIPS core runs simple DSP routines for heart-rate or pulse-ox waveform filtering while 4 KB RAM hosts a small RTOS or state machine. The 10-bit ADC with 13 channels supports multi-sensor front-ends, and the QFN-44 (8x8) package stays compact under 100 mm^2.
מומלץ
Motor Control with PWM and Feedback
The PIC24FJ16GA004-E/ML is a strong match for low-power brushed DC and stepper motor control because its three 16-bit timers and PWM blocks can generate complementary PWM channels with configurable dead-time, while the QEI (Quadrature Encoder Interface) reads encoder feedback for closed-loop position control. With 16 MIPS and a hardware multiply, simple FOC or trapezoidal commutation routines run in real-time on the PIC24F core. The 35 I/O leaves headroom for H-bridge gate drivers and current sensing through the ADC.
מומלץ
USB/HID Peripheral Adapter (non-USB PIC24F)
Although this PIC24FJ16GA004-E/ML part itself does not include USB, it can serve as a companion MCU to a USB-capable PIC24FJ64GB004 or external USB controller, offloading HID report parsing and button-state machine logic. Its 16 MIPS core handles descriptor parsing and debounce while 4 KB RAM buffers HID reports. The 35 I/O accommodates matrix keypads or multi-button game controllers.
מומלץ
Consumer Appliance Control Board
The PIC24FJ16GA004-E/ML is well matched to white-goods and kitchen appliance control boards because the extended -40C to +125C rating tolerates oven, dishwasher, and refrigerator thermal environments, while the nanoWatt idle modes reduce standby power below eco-design limits. The 35 I/O routes relay drivers, keypads, triacs, displays, and UART/SPI/I2C peripherals, while the CTMU enables modern touch-button UIs without extra ICs. The QFN-44 (8x8) package is rugged and solderable on automated SMT lines.
מומלץ
Automotive Body / HVAC Module
The PIC24FJ16GA004-E/ML supports entry-level automotive body and HVAC modules because the -E extended temperature grade and nanoWatt modes suit vehicle cold-crank and dark-current specifications. With 35 I/O, the MCU drives LIN transceivers, stepper motors for HVAC vents, and PWM-controlled LED backlights. Designers typically pair this part with external CAN/LIN transceivers because the PIC24FJ16GA004 does not include a CAN peripheral; use the PIC24HJ128GP502 for CAN.

הערות תכנון
Estimated: The QFN-44 (8x8) exposed thermal pad has typical theta_JA of 31.7 C/W on a 4-layer JEDEC test board. The pad MUST be soldered to a copper ground plane with thermal vias for heat dissipation; failing to solder the EP can cause thermal shutdown under sustained I/O switching loads. Route the EP to a generous copper pour - 1 square inch minimum - for best thermals.
Decoupling: per the Microchip PIC24FJ16GA004 datasheet, place a 0.1 uF ceramic capacitor as close as possible to each Vdd pin within 2 mm, plus a bulk 4.7-10 uF tantalum or ceramic on the main supply trace. Use a ground plane to keep return paths short and to improve EMI. For CTMU-based touch applications, keep the touch pad traces short and shield them with a hatched ground pour.
Do not exceed the absolute maximum Vdd of 3.6 V - this part is NOT 5 V tolerant. The I/O pins are NOT 5 V tolerant; use a level shifter or current-limiting resistor when interfacing to 5 V logic. The PIC24FJ16GA004 does NOT include a USB peripheral; do not use it for USB designs without an external USB transceiver. Do not omit the exposed-pad solder connection or thermals will suffer.
Peripheral Pin Select (PPS) remapping simplifies PCB routing but PPS-mapped inputs must have the corresponding PPS register configured before use; otherwise the peripheral will not see signals. Place the ICSP clock and data pins (RB6/RB7) on a header or test pad for in-circuit programming and debugging. Use Microchip's PICkit 4 or ICD 4 programmer and configure CONFIG bits for the desired oscillator and watchdog behavior.
מידע על תאימות
RoHS compliant per Microchip product page. The -E suffix denotes extended temperature grade (-40C to +125C), not formal AEC-Q100 qualification. For AEC-Q100 qualified PIC24F MCUs in 44-QFN, evaluate the PIC24FJ family automotive variants.
