PIC24FJ64GB004-I/PT 概要
A 16-bit microcontroller (MCU) is a programmable processor that uses a 16-bit data path and instructions, sitting in the embedded hierarchy between 8-bit MCUs (PIC16, AVR, STM8) and 32-bit Cortex-M parts. The PIC24FJ family targets low-power and USB-connected embedded designs that benefit from higher code density and richer peripherals than 8-bit devices, but where a Cortex-M0+/M4 is over-budget on cost or power.
Key features include an on-chip USB 2.0 full-speed OTG transceiver with internal pull-up/pull-down resistors, a 10-bit A/D converter with 13 input channels, four UART, two SPI, two I2C peripherals, five 16-bit timers, and a real-time clock calendar with RTCC alarm. The XLP technology delivers deep sleep currents in the sub-microamp range with multiple power-managed operating modes, making it suited for battery or USB-powered applications.
Architecturally, the PIC24FJ64GB004-I/PT uses a modified Harvard 16-bit core with hardware multiply/divide in a single cycle, a 22K x 24-bit Flash word organization, and a Peripheral Pin Select engine that allows most digital peripherals to be remapped onto alternate pins - a key advantage for board layout versus fixed-pin MCUs. The integrated USB OTG transceiver removes the need for an external TUSB121x PHY, saving 2 to 4 components and avoiding 90-ohm differential trace impedance challenges on dense boards.
Typical applications include USB HID peripherals such as keyboards and custom input devices, USB-to-UART bridge dongles, low-power sensor data loggers with USB charging, medical point-of-care instruments, and consumer accessories requiring USB OTG host or device roles. Its small 44-TQFP footprint and on-chip USB simplify designs that need firmware-updatable USB functionality without an external PHY.
When designing with this part, prioritize the PPS assignment early in the schematic to avoid later re-spins, place a 12 MHz external crystal within 5 mm of OSC1/OSC2 with proper ground guard traces, and follow Microchip's USB hardware design guidelines for the 90-ohm differential D+/D- pair. For lowest sleep current, configure unused peripherals to OFF in firmware and use the deep sleep rather than idle mode.

主な用途
PIC24FJ64GB004-I/PT の用途: 6 件s: USB HID Peripheral (Keyboard / Mouse / Custom Input), USB-to-UART Bridge Dongle, Low-Power Sensor Data Logger with USB Charging, Medical Point-of-Care Instrument, USB OTG Consumer Accessory, Industrial USB Sensor Module.
USB HID Peripheral (Keyboard / Mouse / Custom Input)
The PIC24FJ64GB004-I/PT is ideally matched to USB HID peripheral designs: its integrated USB 2.0 full-speed transceiver removes an external PHY, 4 UARTs and 2 SPIs drive matrix scanning, 5 x 16-bit timers handle debounce, and nanoWatt XLP supports long battery life. Placed as the only MCU on a small PCB with a 12 MHz crystal and USB-C connector; the on-chip PHY and 8 KB RAM let the firmware run a full HID stack plus macro keycode buffers without external memory.
おすすめ
USB-to-UART Bridge Dongle
For USB-to-UART bridge dongles the PIC24FJ64GB004-I/PT provides a single-chip solution: USB device on one side, 4 hardware UARTs on the other, plus 64 KB Flash for protocol conversion code. Using the on-chip USB transceiver eliminates an external FTDI-style bridge IC, dropping BOM cost and PCB area; PPS lets the UART pins be remapped to match the connector pinout without re-spinning the board.
おすすめ
Low-Power Sensor Data Logger with USB Charging
The PIC24FJ64GB004-I/PT is well suited to battery-powered data loggers that need periodic USB connectivity for charging and data offload. The 10-bit / 13-channel ADC reads analog sensors, 8 KB RAM stores logged samples, the USB OTG port handles both charging and data transfer, and nanoWatt XLP deep-sleep modes keep quiescent current in the sub-microamp range between samples - extending coin-cell runtime dramatically.
おすすめ
Medical Point-of-Care Instrument
For handheld medical instruments such as glucose meters or pulse oximeters, the PIC24FJ64GB004-I/PT delivers a 16-bit instruction set for precise ADC averaging, USB for clinic PC connectivity, and 64 KB Flash to host a graphical UI plus measurement firmware. The 10-bit ADC with 13 channels reads multiple sensor types in parallel, and the -40 C to +85 C industrial temperature range supports refrigerated reagent storage.
おすすめ
USB OTG Consumer Accessory
For tablets and phones that need OTG accessory roles such as game controllers or HID remotes, the PIC24FJ64GB004-I/PT supports USB host, device, and OTG modes from the same MCU. The on-chip transceiver simplifies the BOM; 33 digital I/O with PPS handle buttons, LEDs, and force-feedback H-bridge control signals; and 32 MHz / 8 MIPS performance is sufficient for HID, mass-storage, or vendor-class firmware stacks.
おすすめ
Industrial USB Sensor Module
The PIC24FJ64GB004-I/PT fits industrial 24 V-to-USB sensor bridge modules where 3.3 V regulated rail and USB connectivity coexist. Its -40 C to +85 C industrial grade tolerates factory-floor temperature swings, the 13-channel ADC reads 4 to 20 mA loops via sense resistors, and the integrated USB OTG transceiver eliminates external PHY ICs that struggle at industrial temperatures. PPS remapping keeps the PCB layout clean.

設計ノート
Estimated: route the USB D+ / D- differential pair with 90-ohm controlled impedance, length-matched within 150 mil, and isolated from switching signals by a ground guard trace. Place the VBUS detect pin voltage divider within 5 mm of pin 26 and add 4.7 uF bulk capacitance on VDD pins 11 and 28. Per Microchip USB hardware design guide, USB traces should not cross power or clock edges to maintain USB compliance.
Do not leave DISVREG floating when not using the internal 2.5 V regulator - tie it to VSS for normal 3.3 V operation. All VSS pins (10 and 27) must be connected even if the device appears to function with one floating; incomplete VSS bonding can cause programming failures and erratic ADC readings at low temperatures.
Place the 12 MHz crystal or resonator within 5 mm of OSC1 (pin 14) and OSC2 (pin 13), with short symmetric traces and a ground guard ring. Add 22 pF load capacitors tied to VSS. The ICSP programming pins (PGED3/PGEC3 on RB0/RB1 and PGED2/PGEC2 on RB7/RB6) should be brought to a 0.1 inch header to support in-circuit programming without disturbing the PCB layout.
