What is a PIC24F microcontroller? PIC24F devices are 16-bit modified Harvard RISC microcontrollers from Microchip Technology, belonging to the broader microcontroller > microprocessor > semiconductor device taxonomy. They combine a 16-bit data path with 24-bit instruction words, hardware multiply/divide, and Microchip's eXtreme Low Power (XLP) technology. PIC24F parts bridge the gap between 8-bit PIC MCUs and 32-bit ARM Cortex-M devices, making them well suited to cost-sensitive embedded applications that need more performance than 8-bit cores but not the full complexity of an MPU.
The PIC24FJ16GA002 features a 17-bit x 17-bit single-cycle hardware multiplier, a 32-bit/16-bit hardware divider, and seven 16-bit timers. Communication peripherals include two UART modules, two SPI interfaces, and two I2C buses, plus five PWM channels and multiple input capture/output compare modules. Analog resources include a 10-bit ADC with up to 13 channels, two analog comparators, and a real-time clock/calendar with separate 32 kHz oscillator input.
Typical applications include consumer electronics, industrial control, sensor interfacing, low-power portable devices, USB-to-UART bridges, and automotive body electronics. The 28-pin footprint with 21 general-purpose I/O lines simplifies PCB layout while preserving headroom for peripheral expansion. According to Microchip product page information, this part is recommended for design into automotive applications via special ordering codes for automotive-grade variants.
When designing with the PIC24FJ16GA002, ensure the exposed pad of the 28-QFN package is soldered to a sufficiently large ground plane for both thermal dissipation and electrical grounding. Decouple VDD with 100 nF and 10 uF capacitors placed close to the supply pins, and program the device using Microchip's MPLAB X IDE with the XC16 compiler for full access to the modified Harvard instruction set.
This page synthesizes distributor pricing, same-family drop-in alternatives, and practical design notes not collected in any single manufacturer datasheet, complementing the PIC24FJ64GA004 Family Data Sheet with engineering-focused guidance for 28-QFN (ML) pinout selection and component selection.
A 16-bit MCU (microcontroller unit) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), and on-chip peripherals into one package. The PIC24FJ16GA002T-I/ML sits within this taxonomy as a 16-bit MCU, more specifically as a flash-memory 16-bit MCU and a low-power 16-bit MCU, optimized for embedded control applications where deterministic real-time response, low active and sleep currents, and a rich peripheral set are required.

יישומים טיפוסיים
PIC24FJ16GA002T-I/ML מתאים עבור 7 יישוםs: Industrial Sensor Interface Node, USB-to-UART Bridge Dongle, Low-Power Portable Data Logger, Automotive Body Electronics Module, Consumer Appliance Control Board, IoT Edge Sensor Hub, Battery-Powered Health Monitor.
Industrial Sensor Interface Node
The PIC24FJ16GA002T-I/ML fits industrial sensor-interface nodes by combining 16-bit processing at 16 MIPS with a 10-bit ADC (up to 13 channels) and dual UART/SPI/I2C buses. Its 2.0 V to 3.6 V supply and -40 C to +85 C industrial rating cover factory-floor conditions. Dual I2C lets the MCU read two sensor clusters simultaneously, while 5 PWM channels drive valve or motor-control outputs without an external timer IC, reducing BOM and PCB area.
מומלץ
USB-to-UART Bridge Dongle
The PIC24FJ16GA002T-I/ML fits USB-to-UART bridge dongles because of its two UART modules, two I2C buses, and a 32 MHz core capable of running bit-banged USB or a UART-over-USB CDC stack at full speed. The 16 KB Flash is sufficient for CDC class firmware and small command parsers. Industrial temperature rating and 28-QFN footprint suit compact dongle enclosures where thermal headroom and small PCB area matter.
מומלץ
Low-Power Portable Data Logger
The PIC24FJ16GA002T-I/ML fits portable data-logger designs because of its 4 KB SRAM buffer, 16 KB Flash program area, and 32 kHz secondary oscillator input that lets the real-time clock run while the CPU sleeps. With 2.0 V minimum supply, the MCU operates directly from a single Li-Ion or 2xAA cell, while the 21 I/O pins support SD-card, EEPROM, and external sensor interfaces. Tape-and-reel packaging supports volume SMT assembly.
מומלץ
Automotive Body Electronics Module
According to the Microchip product page, the PIC24FJ16GA002 base part is recommended for design into automotive applications. With its 2.0 V to 3.6 V supply, 32 MHz core, 5 PWM channels, and CAN-friendly peripheral mix, it fits body-control modules driving LEDs, mirrors, and small actuators. The 28-QFN package fits tight under-dash enclosures, and special automotive ordering codes extend qualification to AEC-Q100 requirements.
מומלץ
Consumer Appliance Control Board
The PIC24FJ16GA002T-I/ML fits consumer appliance control boards by offering 16-bit performance at a cost competitive with 8-bit designs. The 5 PWM outputs drive BLDC or brushed-DC motors for fans and pumps; dual I2C reads keypad and temperature sensors; the 10-bit ADC monitors current and voltage. Industrial temperature rating, exposed-pad QFN, and tape-and-reel packaging suit high-volume appliance manufacturing lines.
מומלץ
IoT Edge Sensor Hub
The PIC24FJ16GA002T-I/ML fits IoT edge sensor hubs requiring local decision-making before RF transmission. Its 32 MHz core and 17 x 17 hardware multiplier execute sensor-fusion algorithms in real time, while the dual UART/SPI/I2C peripherals simultaneously talk to a wireless module, an EEPROM, and multiple sensors. Industrial-grade operating range and the small 28-QFN footprint allow deployment in harsh indoor/outdoor enclosures.
מומלץ
Battery-Powered Health Monitor
The PIC24FJ16GA002T-I/ML fits wearable health monitors by offering enough MIPS for simple ECG or pulse-oximetry DSP while drawing low active current. Its 2.0 V minimum supply operates from a single coin cell, and the 4 KB SRAM buffers raw sample data between transmission bursts. The 28-QFN (6x6 mm) footprint fits wristband form factors, and dual I2C lets one bus run the sensor while the other drives an OLED display.

הערות תכנון
Estimated: The 28-QFN package has a 6 mm x 6 mm body with a center exposed pad (EP) that MUST be soldered to the PCB for both electrical grounding and thermal dissipation. Recommended land pattern per IPC-7351 calls for a 3.0 mm x 3.0 mm EP pad with 0.4 mm pitch perimeter pads. Place a 4 x 4 thermal via array (0.3 mm drill, 0.5 mm pitch) under the EP and stitch VDD/VSS planes around it to minimize ground bounce.
Place a 100 nF ceramic decoupling capacitor as close as possible to each VDD/VSS pin pair, with a bulk 10 uF ceramic on the main VDD rail within 5 mm of the MCU. For analog-sensitive applications, decouple AVDD separately from AVDD with its own 100 nF capacitor and a small ferrite bead. The PIC24FJ16GA002 internal voltage regulator supplies the core from VDD; do not draw external load from any internal rail node.
Do not program the device with a debugger while VDD is below 2.0 V or above 3.6 V; voltage deviations outside this range can corrupt Flash during in-circuit programming. Use MPLAB X IDE with the XC16 compiler and a PICKit 3 or ICD 4 for safe programming. Note that the 'T' suffix on the part number indicates tape-and-reel packaging, not any silicon difference, so firmware is identical to the non-T PIC24FJ16GA002-I/ML.
Keep the 32 kHz secondary oscillator traces (RA7/RA8 on the 28-QFN) short and symmetric; a crystal placed more than 5 mm from the MCU may oscillate unreliably at low supply voltages. For designs where EMI is critical, place a 4.7 k to 10 k pull-up on MCLR and a series resistor on PGED/PGEC to limit inrush during programming. Route UART and SPI traces with characteristic impedance controlled to 50 ohm if traces exceed 25 mm.
מידע על תאימות
RoHS compliant per Microchip product page. The base PIC24FJ16GA002 part is recommended for design into automotive applications via special ordering codes for automotive-grade (AEC-Q100) variants; the PIC24FJ16GA002T-I/ML itself is industrial-grade and not AEC-Q100 qualified - choose the automotive part number for AEC-Q100 designs.
