PIC24FJ64GB004-I/ML - 32MHz 16-Bit USB MCU | Microchip
部品番号: PIC24FJ64GB004-I/ML ✓ 生産中PIC24FJ64GB004-I/ML 概要
A microcontroller is a programmable semiconductor that integrates a processor core, memory, peripherals, and I/O into one device. The PIC24 family belongs to the broader microcontroller, embedded-processor, and semiconductor hierarchy. Its modified Harvard architecture supports efficient access to program memory and data memory, while the XLP design emphasizes reduced power consumption in portable and low-duty-cycle products.
The PIC24FJ64GB004 combines a maximum clock frequency of 32 MHz with up to 16 MIPS of instruction throughput. Its 64 KB Flash supports firmware storage, while 8 KB of RAM accommodates working data, buffers, and interrupt service routines. Full-Speed USB OTG adds a practical interface for control transfers, data exchange, and connected peripheral functions without requiring a separate USB controller.
The integrated peripherals include a 17-bit single-cycle hardware multiplier, a 16-bit hardware divider, and a 16-bit working-register array. An 8 MHz internal oscillator with a 4x PLL option provides clock flexibility, while multiple divide options help designers balance processing speed and power use. The C compiler-oriented architecture also gives embedded developers an efficient path for compact control firmware.
Typical uses include USB-connected data loggers, compact industrial control modules, battery-operated field instruments, configuration tools, human-interface equipment, and low-power monitoring products. The 64 KB memory capacity is particularly appropriate for products needing moderate local code and data storage without moving to a larger microcontroller architecture.
A critical design consideration is power behavior. The internal oscillator and PLL settings determine processing throughput, active current, and USB timing margin. Firmware should therefore use the slowest acceptable clock configuration during idle periods, keep USB transceiver and pull-up circuitry close to the device, and validate timing across the intended voltage and temperature range.
This product overview combines the manufacturer specifications with application-oriented guidance for USB, low-power, and embedded-control designs. It also highlights the limits of a direct replacement decision: the footprint, electrical functions, USB behavior, and firmware support must all be checked before assigning a different PIC24 member to an existing board.

主な用途
PIC24FJ64GB004-I/ML の用途: 6 件s: USB Connected Data Logger, Industrial Configuration Tool, Battery-Operated Field Instrument, USB Human-Interface Device, Compact Motor-Control Module, Portable Sensor Node.
USB Connected Data Logger
The PIC24FJ64GB004-I/ML fits a compact USB data logger because its 32 MHz processor and 16 MIPS throughput provide responsive sampling control, while 64 KB of Flash stores firmware and 8 KB of RAM handles acquisition buffers. Full-Speed USB OTG permits direct connection to a host computer without a separate interface controller. The design should reserve memory for descriptors, use interrupt-driven transfers to avoid blocking acquisition, and verify that the logger's sample rate remains below the available USB throughput.
おすすめ
Industrial Configuration Tool
The PIC24FJ64GB004-I/ML is appropriate for a USB-connected industrial configuration tool that must store firmware, maintain protocol state, and respond to host commands. Its 16-bit PIC24 architecture, 64 KB Flash, and 8 KB RAM are sufficient for compact menus, parameter tables, and diagnostic data. USB OTG reduces the external chip count, although designers should isolate the USB interface from external wiring, implement robust firmware updates, and include hardware protection suited to the industrial environment.
おすすめ
Battery-Operated Field Instrument
The nanoWatt XLP PIC24FJ64GB004-I/ML suits battery-operated field instruments where processing capability must be balanced against energy use. The internal 8 MHz oscillator, 4x PLL option, and multiple divide options let firmware reduce clock activity when measurements are not active. Operation down to 2 V at 16 MHz supports low-voltage designs, while 64 KB of Flash accommodates local calibration and logging code. Sleep behavior, analog-peripheral shutdown, and USB connection state should be validated as parts of the complete power budget.
おすすめ
USB Human-Interface Device
The PIC24FJ64GB004-I/ML can implement a USB human-interface device because it combines a 32 MHz 16-bit processor with native Full-Speed USB On-The-Go support. Firmware can service HID reports while the MCU manages buttons, indicators, sensors, or other local controls. The 8 KB RAM is suitable for report buffers and control state, but it requires disciplined allocation if display data or complex protocols are added. USB enumeration, suspend current, and wake behavior should be tested together on the finished board.
おすすめ
Compact Motor-Control Module
The PIC24FJ64GB004-I/ML can serve as the supervisory controller in a compact motor-control module when the primary motor driver performs the high-current switching. The device's 32 MHz execution speed supports digital control calculations, current monitoring, fault handling, and communication, while the 17-bit single-cycle multiplier is useful for fixed-point control mathematics. Its 64 KB Flash and 8 KB RAM suit moderate control loops. Pin multiplexing, ADC timing, watchdog behavior, and safe output states must be checked against the selected power stage.
おすすめ
Portable Sensor Node
The PIC24FJ64GB004-I/ML is well suited to a portable sensor node that samples local inputs, stores compact event data, and exchanges information through USB when connected. Its 8 MHz internal oscillator and PLL options provide a flexible performance range, while 64 KB Flash can hold drivers, filtering, and communication code. The 8 KB RAM is adequate for modest sample buffers but not large offline logs. Designers should use interrupt-driven acquisition, shut down unused peripherals during idle intervals, and account for sensor and USB-interface current in the battery calculation.

設計ノート
Route the USB D+ and D- pair as a short, impedance-controlled differential pair on the same board layer where practical, with continuous ground reference beneath the pair. Keep the USB connector, protection components, and optional 1.5 kOhm pull-up network close to the device. Minimize stubs and place ESD protection at the connector rather than beside the MCU, because surge current must reach the protection device before reaching the pins.
Calculate regulator dissipation before fixing the 3.3 V supply topology. Estimated: with a 5 V input, a 3.3 V output, and a 50 mA MCU load, the regulator dissipates (5 V - 3.3 V) x 0.05 A = 0.085 W. Include USB transceiver, pull-up, and external-load current in the same budget. Select the input range and bypass capacitors from the manufacturer guidance, especially when the USB supply and MCU supply share a connector.
Use the exposed-pad structure and PCB copper as part of heat spreading for the 44-pin QFN. The package's small 8 mm by 8 mm footprint makes pad soldering and via placement important to electrical and thermal performance. Follow the manufacturer's land-pattern and reflow instructions, inspect exposed-pad fillets after assembly, and avoid long pad heating if the assembly includes components with limited temperature tolerance.
Do not assume that two related PIC24FJ64GB004 orderings are firmware- and footprint-identical. USB endpoint behavior, temperature classification, qualification, programming, and packing can vary even when the core clock and memory sizes match. Before replacing the device, compare the pin-description tables, USB register implementation, oscillator limits, memory organization, and operating-temperature requirements. Update firmware and boot code whenever the selected device variant changes.
コンプライアンス情報
No explicit compliance declarations for this exact ordering code were identified. Confirm RoHS, REACH, AEC-Q100, lead-free, halogen-free, and conflict-mineral status with the manufacturer before procurement.
