PIC24FJ64GB004T-I/PT - 64KB Flash 16-bit USB MCU 44-TQFP | Microchip
MPN: PIC24FJ64GB004T-I/PT ✓ Hoạt độngPIC24FJ64GB004T-I/PT Tóm tắt
A PIC24F microcontroller is a 16-bit modified-Harvard CPU from Microchip's PIC24 family, bridging the 8-bit PIC16/PIC18 architectures and the 32-bit PIC32 family. PIC24F devices target low-power, USB-equipped, and human-interface applications, integrating peripherals such as USB OTG, comparators, RTCC, and capture/compare/PWM modules on a single die. Within the broader Microcontroller -> 16-bit MCU -> PIC24F -> nanoWatt XLP taxonomy, the PIC24FJ64GB004 sits in the 64-pin-or-fewer, full-speed USB tier.
Key features include a C-compiler-optimized instruction set with a 17-bit x 17-bit single-cycle hardware multiplier and 16-bit hardware divider, 16 working registers, an 8 MHz internal oscillator with 4x PLL option, 33 digital I/O pins, 7 timers, 5 PWM channels, 3 analog comparators, an RTCC, and 13 ADC channels with 10-bit resolution. The integrated USB 2.0 full-speed OTG controller adds a PHY and internal pull-up, eliminating the external transceiver.
Typical applications include USB peripherals (HID, CDC, mass-storage), consumer audio accessories, embedded human-interface devices, low-power data loggers, and educational/development boards. The wide 2.0V to 3.6V VDD range permits direct Li-ion battery operation, and the on-chip RTCC supports calendar functions for metering products.
When designing with this MCU, allocate 4 mA of source/sink headroom per pin and provide a 0.1 uF decoupling cap adjacent to every VDD/VSS pair. The USB D+/D- traces should be 90 ohm differential and routed length-matched for full-speed compliance. Always set the CONFIG words for the right oscillator mode before code execution.

Ứng dụng tiêu biểu
PIC24FJ64GB004T-I/PT phù hợp cho 7 Áp dụngs: USB HID Peripherals, USB CDC Virtual COM Port, USB Mass Storage Devices, Industrial Sensor Interface Module, Battery-Powered Data Logger, Consumer Audio Accessory, Educational / Development Board Platform.
USB HID Peripherals
The PIC24FJ64GB004T-I/PT's on-chip USB 2.0 Full-Speed OTG transceiver with internal pull-up and dedicated DMA channels makes it ideal for USB HID peripherals such as keyboards, mice, game controllers, and custom input devices. With 64 KB of Flash the part hosts the full Microchip USB HID stack plus composite descriptor logic, while 8 KB RAM accommodates HID report buffers without external memory. Designers eliminate the external PHY and 12 MHz crystal that classic 8051 designs required, shrinking PCB area by roughly 30 percent. The 32 MHz core executes the USB stack polling loop in well under the 1 ms USB frame budget, leaving MIPS headroom for application code.

USB CDC Virtual COM Port
For USB-to-serial bridge designs, the PIC24FJ64GB004T-I/PT acts as a CDC ACM device that appears as a COM port on a host PC. The integrated USB transceiver and 64 KB of Flash hold the CDC class driver plus application-level protocol handling, while the 8 KB RAM buffers full-speed bulk transfers without flow-control glitches. The 33 I/O pins expose UART, SPI, and I2C pins to bridge legacy microcontrollers, sensors, or industrial equipment to USB hosts. The 2.0-3.6 V VDD range permits direct battery-powered deployment, and nanoWatt XLP sleep mode draws less than 1 uA when the host suspends the bus.

USB Mass Storage Devices
Engineers building USB flash drives, SD-card readers, or data-logger export dongles benefit from the PIC24FJ64GB004T-I/PT's USB Mass Storage Class (MSC) bulk-only transport support. The 64 KB Flash stores the MSC BOT state machine plus FAT16/32 file-system driver, and the 8 KB RAM handles 512-byte SCSI block transfers at full-speed USB throughput. SPI or parallel interfaces connect to NAND/SD media, while the 32 MHz CPU keeps the BOT handler comfortably below the 1 ms USB frame budget. NanoWatt XLP sleep mode cuts idle current under 1 uA for battery-powered portable storage devices.

Industrial Sensor Interface Module
The PIC24FJ64GB004T-I/PT's 13-channel 10-bit ADC, 3 analog comparators, 5 PWM channels, and 7 timers cover the typical signal-conditioning needs of an industrial sensor interface. The 64 KB Flash holds Modbus RTU or CANopen protocol stacks, while the 8 KB RAM buffers multiple sensor readings before transmission. The -40C to +85C industrial temperature grade and 2.0-3.6 V VDD range operate reliably in factory cabinets. The USB OTG port enables field-service technicians to connect a tablet for diagnostics and firmware updates without opening the enclosure.

Battery-Powered Data Logger
With nanoWatt XLP deep-sleep current below 1 uA, the PIC24FJ64GB004T-I/PT enables multi-year battery life in unattended data loggers that wake periodically to sample sensors. The integrated RTCC schedules wake events with calendar accuracy, while the 64 KB Flash stores several weeks of compressed time-stamped samples. The 2.0-3.6 V VDD range accommodates direct Li-ion or 2xAA battery operation across discharge. USB OTG enables field data extraction to a phone or tablet without removing the battery.

Consumer Audio Accessory
Audio accessories such as USB headsets, DAC dongles, and MIDI controllers leverage the PIC24FJ64GB004T-I/PT for USB Audio Class 1.0 device implementation. The 33 I/O pins drive I2S/I2C codecs, button inputs, and LED indicators, while the 5 PWM channels produce visual feedback or motor control. The 64 KB Flash stores USB Audio class descriptors plus DSP filters, and the 32 MHz CPU sustains 48 kHz stereo sample flow over USB isochronous endpoints. NanoWatt XLP sleep mode saves power when the host suspends audio streaming.

Educational / Development Board Platform
The PIC24FJ64GB004T-I/PT is the canonical MCU for Microchip's Explorer 16/32 development board PIMs, giving students and engineers a fully-documented 16-bit platform with USB connectivity, RTCC, ADC, PWM, and timers exposed via on-board peripherals. The C-compiler-optimized PIC24 instruction set and free MPLAB X IDE plus XC16 compiler provide a low-cost learning path from 8-bit PIC to 32-bit ARM. The 64 KB Flash accommodates moderate-sized projects with bootloader support, while 8 KB RAM runs a small RTOS for multitasking exercises.

Ghi chú thiết kế
Place a 0.1 uF ceramic decoupling capacitor within 3 mm of every VDD/VSS pin pair on the PIC24FJ64GB004T-I/PT, and add a bulk 10 uF tantalum or ceramic cap near the package. The USB VUSB pin (pin 36) requires its own 0.1 uF decoupling cap to stabilize the internal 3.3 V USB transceiver regulator. Operating voltage range is 2.0 V to 3.6 V; the USB module is not specified below 3.0 V per the datasheet. When USB is unused, leave VUSB floating and disable the USB module in firmware to save 200 uA.
Route the USB D+ (pin 37) and D- (pin 38) traces as a 90 ohm differential pair with length matching within 2 mm, keep them short (under 50 mm total), and surround them with a continuous ground pour referenced to VSS. Per the USB 2.0 specification, the differential impedance must be 90 ohms +/- 10 percent to comply with full-speed signaling. Avoid routing the differential pair near clock traces, switching regulators, or other high-frequency signals to minimize radiated EMI.
Always configure the CONFIG words (FOSC, FWDT, FPOR, etc.) before the device executes user code; an incorrect PLL or oscillator setting can lock the MCU out of In-Circuit Serial Programming (ICSP). The MCLR pin (pin 43) must be pulled high through a 10 kohm resistor for normal operation; leaving it floating causes intermittent resets. When migrating from the PIC24FJ64GB004-I/PT (tray) to the PIC24FJ64GB004T-I/PT (tape and reel), verify your pick-and-place feeder accepts 7-inch reels before scheduling production.
For the 44-pin TQFP (10x10 mm), allocate at least 0.5 mm clearance between package edges and adjacent traces to avoid solder-bridging. Use a 4-layer PCB with a dedicated ground plane on layer 2 for best EMI performance; on 2-layer boards, stitch the ground pours with vias every 5 mm. The exposed thermal pad is not present on this TQFP package, but a 10x10 mm copper pour under the part still reduces thermal stress by 5-8 C under heavy peripheral load.
Pin 43 is the MCLR reset input; ensure the 10 kohm pull-up resistor sits within 10 mm of the pin and that no high-current traces route nearby to prevent false resets from EMI. The OSC1/OSC2 crystal pins (41 and 42) should be guarded by a ground ring and the crystal traces kept under 5 mm to minimize parasitic capacitance. For noisy environments, place a 1 Mohm resistor across the crystal to start oscillation reliably across the full -40C to +85C range.
