PIC24FJ64GB002-I/ML - 32MHz 64KB USB MCU | Microchip
MPN: PIC24FJ64GB002-I/ML ✓ Hoạt độngPIC24FJ64GB002-I/ML Tóm tắt
A microcontroller is the central programmable component of an embedded system. It executes application firmware, reads inputs, controls outputs, and manages communication interfaces. The PIC24FJ family uses a 16-bit RISC architecture and belongs to the broader hierarchy of embedded processors, microcontrollers, and semiconductor devices. The PIC24FJ64GB002-I/ML combines that general-purpose control capability with an integrated USB device controller and energy-conscious operation.
Key features include 64 KB of Flash program memory, 8 KB of SRAM, a maximum clock frequency of 32 MHz, and Full-Speed USB support. The -I grade is associated with an industrial temperature range, while the /ML package suffix identifies the 28-pin QFN configuration. Basic Code-Guard security adds programmable protection for controlled access to Flash memory, helping protect firmware in connected embedded products.
At 3.3 V, the device can execute up to 16 MIPS. This performance level supports responsive control loops, USB-connected data acquisition, human-interface functions, and compact peripheral control while retaining the simplicity of a single-chip embedded design. Its integrated USB capability can reduce the need for external host-control chips and associated board space when the system requires a direct USB connection.
Typical uses include USB-connected industrial controls, compact data-acquisition modules, USB instrumentation, medical and laboratory peripherals, and low-power embedded nodes. The 28-pin QFN package also suits compact portable products where board area is constrained and production equipment can reliably assemble a fine-pitch leadless package.
When designing a PCB around the PIC24FJ64GB002-I/ML, confirm the exact 28-pin land pattern, exposed-pad requirements, decoupling, programming interface, and USB signal-routing recommendations in the manufacturer datasheet. Keep USB traces compact, provide the specified clock and bypass components, and verify every unused pin configuration before releasing the layout.

Ứng dụng tiêu biểu
PIC24FJ64GB002-I/ML phù hợp cho 6 Áp dụngs: USB Data-Acquisition Module, Compact Industrial Control Interface, USB Connected Sensor Node, Portable Medical Accessory, USB Instrumentation Peripheral, Low-Power Embedded Control Node.
USB Data-Acquisition Module
The PIC24FJ64GB002-I/ML fits a compact USB data-acquisition module because it combines a 16-bit PIC RISC core, 64 KB of Flash, 8 KB of RAM, and Full-Speed USB in one controller. At 3.3 V, the device can execute up to 16 MIPS, providing useful processing headroom for signal conditioning, digital filtering, status handling, and host communication. The integrated USB controller can simplify the connection between the acquisition circuitry and a computer or embedded host. Place the MCU close to the USB connector and follow the manufacturer’s routing and bypass recommendations to limit signal integrity and EMC risks.

Compact Industrial Control Interface
The PIC24FJ64GB002-I/ML is suitable for compact industrial control panels that need local logic, USB connectivity, and modest data storage without a separate communications processor. Its 32 MHz maximum CPU frequency supports responsive handling of switches, indicators, sensors, and configuration commands, while the -I grade suits industrial operating conditions. The 64 KB Flash provides room for control firmware, and the 8 KB RAM can hold operational variables and communication buffers. Validate the complete peripheral map and pin multiplexing in the datasheet, especially for USB, programming, clock, and digital I/O assignments on the 28-pin QFN.

USB Connected Sensor Node
The PIC24FJ64GB002-I/ML can serve as the controller in a compact USB-connected sensor node that reads digital or analog-front-end signals and presents data to a host. Its 16-bit architecture and up-to-16-MIPS execution rate at 3.3 V support measurement handling, filtering, and control tasks, while 8 KB of RAM accommodates working data and USB buffering. The integrated Full-Speed USB interface removes the need for a discrete USB controller in straightforward designs. Keep sensitive sensor circuitry separated from digital return paths and use the manufacturer’s recommended grounding and decoupling arrangement to preserve measurement quality.

Portable Medical Accessory
The PIC24FJ64GB002-I/ML is appropriate for compact medical accessories that require a USB interface, moderate embedded processing, and low-power operation. The 64 KB Flash and 8 KB RAM support device firmware, configuration handling, and short-lived data buffers, while the 32 MHz core can manage control logic and communication tasks. The 28-pin QFN package helps reduce PCB area in portable products. Because medical product requirements extend beyond component selection, engineers must independently validate electrical safety, reliability, software risk controls, and applicable regulatory requirements for the complete product.
Được đề xuất
USB Instrumentation Peripheral
The PIC24FJ64GB002-I/ML suits USB instrumentation peripherals where a host computer supplies configuration commands and the embedded controller manages local functions. Its 16-bit RISC architecture, 64 KB Flash, and 8 KB RAM provide enough resources for command parsing, status reporting, calibration values, and basic control loops. Full-Speed USB offers a direct connection to a host without an external USB interface device. Designers should use short, impedance-controlled USB routing, provide the required passive components, and confirm reset and programming access on the final 28-QFN layout before fabrication.
Được đề xuất
Low-Power Embedded Control Node
The PIC24FJ64GB002-I/ML is designed for embedded control nodes where low-power operation, a 16-bit processor, and integrated USB are useful. Its eXtreme low power technology positions it for systems that spend part of their operating time in reduced-activity states while retaining responsiveness to local inputs and USB commands. The 64 KB Flash stores application code and 8 KB RAM supports working state. Successful implementation depends on selecting the correct clock configuration, peripheral enable states, and sleep behavior through the Microchip toolchain and validating the complete power budget on the target board.

Ghi chú thiết kế
Confirm the exact 28-pin QFN land pattern, pin-1 orientation, exposed-pad connection, and solder-mask requirements against the manufacturer package drawing before releasing the PCB. The device is supplied in a 6 x 6 mm leadless package, so assembly capability and inspection coverage should be checked alongside the electrical layout. Keep USB and programming nets accessible, and avoid placing tall components near pins that must remain clear for soldering and inspection.
Route Full-Speed USB as a controlled-impedance interface and keep the USB device connection short. Follow the manufacturer’s recommended topology for USB data lines, pull components, series impedance, and the nearby clock and decoupling network. Place required bypass capacitors close to their associated supply pins with short ground returns, and separate noisy digital switching paths from sensitive analog inputs to reduce coupling into measurement and control circuits.
Do not assume that every /ML device in the PIC24FJ family has identical peripheral mapping, memory capacity, USB behavior, or active pin functions. Use the device-specific pin-description table and ordering information to assign every ball, including programming, reset, clock, USB, and no-connect positions. Also verify the required production packing format, because the -I/ML and -T-I/ML ordering codes should not be treated as interchangeable without assembly review.
Plan the power tree around the 2.5 V to 3.3 V operating range and account for both active and low-power states. Estimated power use must be calculated from the selected clock, peripheral configuration, output loading, USB activity, and the regulator efficiency because no fixed application-level current can be assigned to the MCU alone. Validate brownout behavior, startup timing, and supply-noise margins on hardware before enabling advanced peripherals or reducing the operating clock.
Thông tin tuân thủ
The -I/ML ordering code identifies the industrial-grade device, and a component listing classifies the part as automotive. Compliance and AEC-Q100 status must be confirmed for the exact MPN using Microchip documentation before production release.
