PIC24FJ48GA002T-I/ML Overview
A PIC microcontroller (MCU) is a compact, self-contained computing subsystem built around a CPU, program memory (Flash), data memory (RAM), and a rich set of on-chip peripherals. PIC24F devices sit in Microchip's 16-bit MCU portfolio, sitting above the 8-bit PIC10/12/16/18 families and below the 32-bit PIC32MX/dsPIC lines. Within the broader taxonomy, PIC24F MCUs belong to the microcontroller -> embedded processor -> semiconductor -> integrated circuit hierarchy, and are typically deployed where 8-bit performance is insufficient but cost/footprint precludes a 32-bit part.
Key features of the PIC24FJ48GA002 include a 16-bit modified Harvard architecture, a wide operating voltage range of 2.0V to 3.6V, multiple communication peripherals (UART, SPI, I2C), a 10/12-bit ADC, and Microchip's nanoWatt Technology for low-power sleep modes. The 28-QFN package provides compact 6x6 mm footprint with an exposed pad for improved thermal dissipation, suitable for space-constrained designs.
The device is engineered around Microchip's 16-bit modified Harvard architecture with separate program and data buses, enabling single-cycle instruction fetch and most instructions to complete in one cycle. This delivers throughput close to 16 MIPS at 32 MHz, balancing performance with the low-power capabilities characteristic of the PIC24F family.
Typical applications include low-cost consumer electronics, sensor interfaces, battery-powered industrial sensors, USB device controllers, and general-purpose embedded control. Its wide voltage tolerance and rich peripheral set make it ideal for handheld instrumentation and IoT edge nodes. Designers should evaluate memory headroom and consider the industrial temperature range when selecting this part for outdoor or factory-floor deployments.

Typical Applications
PIC24FJ48GA002T-I/ML is suitable for 6 applications: Industrial Sensor Interface Node, Battery-Powered IoT Edge Device, Consumer Electronics User Interface Controller, USB HID Peripheral Controller, Handheld Test & Measurement Instrument, Home Automation Lighting Controller.
Industrial Sensor Interface Node
The PIC24FJ48GA002T-I/ML is well-suited for industrial sensor interface nodes due to its 16-bit MIPS performance (16 MIPS at 32 MHz) and 48 KB Flash supporting full Modbus RTU or custom protocol stacks. The 2.0-3.6 V supply tolerates 24 V industrial rails when paired with a 3.3 V LDO, while the -40C to +85C industrial temperature grade handles factory floor thermal stress. The on-chip 10/12-bit ADC and UART peripherals directly interface analog sensors and RS-485 transceivers. Compared with 8-bit PIC16 alternatives, the 16-bit core enables 32-bit math for calibration and filtering in sensor conditioning firmware, reducing external DSP requirements.
Recommended
Battery-Powered IoT Edge Device
Battery-powered IoT edge devices benefit from the PIC24FJ48GA002T-I/ML's nanoWatt Technology sleep modes, with deep-sleep currents in the microamp range extending Li-ion battery life to years. The 2.0-3.6 V supply operates directly from a single-cell Li-ion or 2x AA alkaline pack, and the 48 KB Flash accommodates OTA bootloader plus application firmware. The integrated I2C and SPI peripherals connect to common low-power sensors and radios (e.g., LoRa, BLE modules). Unlike 32-bit Cortex-M0+ alternatives, the PIC24F retains simpler toolchains (MPLAB X IDE, XC16) for cost-constrained IoT designs.
Recommended
Consumer Electronics User Interface Controller
Consumer user-interface controllers like remote controls, e-reader buttons, or appliance keypads leverage the PIC24FJ48GA002T-I/ML's 21 GPIO pins to scan key matrices, drive LED indicators, and handle capacitive touch via software. The 32 MHz CPU is sufficient for debouncing, capacitive sensing algorithms, and LCD segment driving. Its small 6x6 mm QFN footprint fits inside cramped enclosures, and the wide 2.0-3.6 V supply supports direct 2x AA battery operation. Unlike simpler 8-bit PIC12/16 parts, the 16-bit core simplifies AES-like encryption for paired-device authentication.
Recommended
USB HID Peripheral Controller
USB Human Interface Device (HID) peripherals such as custom keyboards, pointer devices, or game controllers benefit from the PIC24FJ48GA002T-I/ML's 16 MIPS throughput and 48 KB Flash supporting USB HID class stacks. While this specific variant lacks native USB, paired with an external USB-serial bridge (e.g., MCP2200) or used with sibling PIC24F USB parts, it enables cost-effective HID implementations. The 21 GPIO directly drives button matrices and LEDs without external expanders. The -40C to +85C industrial range covers automotive cabin and outdoor installations.
Recommended
Handheld Test & Measurement Instrument
Handheld digital multimeters, clamp meters, and insulation testers leverage the PIC24FJ48GA002T-I/ML's 10/12-bit ADC for voltage/current measurement and 8 KB RAM for sample buffering. The 16 MIPS CPU executes RMS calculations and digital filtering in real time, while the wide supply range supports direct Li-ion battery packs. The industrial temperature grade ensures stable readings in outdoor or workshop environments. Compared with 8-bit PIC16, the 16-bit core doubles math precision for accurate measurements without external DSP.
Recommended
Home Automation Lighting Controller
Home automation lighting controllers use the PIC24FJ48GA002T-I/ML to drive PWM outputs for dimmable LED fixtures, communicate with wireless modules over UART/SPI, and execute time-based schedules. The 48 KB Flash accommodates DMX-512, DALI, or proprietary lighting protocols, while the -40C to +85C industrial temperature ensures reliability in ceiling fixtures. Its small QFN package integrates into compact driver PCBs. Compared with 32-bit alternatives, the PIC24F offers lower cost and simpler certification paths for residential smart-lighting products.

Key Differentiators

- Maximum Flash memory in this QFN footprint within the GA002 family (vs PIC24FJ32GA002T-I/ML)
- PIC24F family low-power leadership (vs dsPIC33FJ16MC102T-I/ML)
Design Notes
The 28-QFN (6x6 mm) package has an exposed thermal pad on the underside that MUST be soldered to a PCB pad for both mechanical reliability and thermal dissipation. Microchip's QFN land pattern recommendation uses NSMD pads with solder mask defined openings of approximately 0.30 mm pitch. Vias in the thermal pad (filled or tented with solder mask) reduce thermal resistance from the die to inner copper planes. Recommended via count: 5-9 thermal vias in a 3x3 grid array.
Place 100 nF decoupling capacitors as close as possible to each VDD pin (pins 7, 28), with a 10 uF bulk capacitor on the main 3.3 V supply rail. The PIC24F is sensitive to VDD ripple above 50 mV during ADC conversions. For ADC accuracy, add a ferrite bead between digital and analog VDD if analog and digital supplies are separately routed. According to Microchip datasheet DS39934, hold-time on MCLR during power-up should be at least 100 us after VDD reaches 2.0 V.
Do not leave the MCLR pin floating; tie through a 10 kohm pull-up to VDD to ensure proper reset behavior. For ICSP (In-Circuit Serial Programming), dedicate pins RB6/PGC and RB7/PGD to programming and ensure they are not driven by external circuitry during programming. Configuration bits must be set correctly to enable the internal oscillator and disable the watchdog unless explicitly required; the default FOSC setting selects the internal RC oscillator.
Keep traces to the 32 MHz oscillator (OSC1/OSC2) short and guarded by ground pour to minimize EMI pickup. If using the internal 8 MHz RC oscillator, the FCKSM configuration bits should be set to disable clock switching for safety-critical applications. For UART communications up to 115200 baud, the internal oscillator provides adequate accuracy; for higher rates, an external crystal is recommended.
Compliance Information
RoHS and REACH compliant per Microchip product page. Not AEC-Q100 qualified - the part is targeted at industrial/consumer applications; for automotive designs consider AEC-Q100 qualified PIC24 variants.
