PIC24FJ128GB106-I/PT 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and a mix of peripherals (timers, communication blocks, analog blocks) on one die. The PIC24F family sits in the 16-bit MCU hierarchy between 8-bit PIC MCUs and 32-bit Cortex-M devices, offering higher throughput than 8-bit parts while keeping power consumption low. The PIC24FJ128GB106 specifically targets USB-connected embedded designs that need more headroom than 8-bit MCUs but do not require a digital signal processor.
Key features include 128 KB Flash, 16 KB RAM, hardware crypto engine, true random number generator, USB 2.0 OTG with integrated transceiver, three I2C, three SPI, four UART channels, 23 timers, a 10-bit 500 ksps ADC with up to 16 channels, and a CTMU for capacitive touch. XLP technology supports deep sleep with RTCC and a deep-sleep wake source, enabling battery-powered designs that must run for years on a single cell. Peripheral Pin Select remaps digital functions to physical I/O without rewiring, freeing layout from fixed peripheral pin assignments.
The PIC24FJ128GB106 uses a 16-bit modified Harvard architecture with a 24-bit instruction word and a 16-bit data path, delivering 16 MIPS at 32 MHz. The integrated USB OTG controller with on-chip full-speed transceiver eliminates external PHY complexity, while PPS and the rich peripheral set make this device well suited to human-interface, sensor hub, and connectivity applications where USB device or host roles are required.
Typical applications include USB peripherals (HID, CDC, MSD), industrial data loggers, medical telemetry, e-metering, and battery-powered sensor nodes. The 64-pin TQFP variant is chosen when fewer than 50 GPIOs and 128 KB of code are sufficient, leaving room for cost-down versus the 80-pin GB108 or 100-pin GB110.
When designing with this MCU, plan the I/O map using PPS before PCB layout and reserve the 16 KB RAM for USB class descriptors and packet buffers. Use the on-chip CTMU for cost-effective touch keys without dedicated hardware, and follow Microchip application notes for USB enumeration and OTG role swapping. This page synthesizes distributor pricing, drop-in compatible PIC24F alternatives, and practical design notes that go beyond the manufacturer datasheet summary, enabling fast BOM decisions for USB-enabled embedded designs.

USB HID / CDC / MSD Peripherals
The PIC24FJ128GB106-I/PT's integrated USB 2.0 Full-Speed OTG controller with on-chip transceiver makes it ideal for USB peripherals implementing HID (Human Interface Devices), CDC (Communications Device Class), and MSD (Mass Storage) classes. The 128 KB Flash is large enough for the Microchip MLA USB stack plus application code, while 16 KB RAM holds class descriptors and packet FIFOs. Per Microchip datasheet (DS39940), the OTG controller supports device, host, and dual-role modes without external PHY components, reducing BOM cost and PCB footprint for keyboards, custom input devices, USB-to-UART bridges, and USB memory sticks.
おすすめ
Industrial Data Loggers
The PIC24FJ128GB106-I/PT fits industrial data loggers because of its industrial -40C to +85C temperature grade, 16 KB RAM for buffering sensor samples, and 128 KB Flash for logging firmware and local data tables. The 10-bit 500 ksps ADC with up to 16 channels handles mixed analog sensor inputs, while three SPI and three I2C buses connect to external sensors, EEPROMs, or RTCs. Per Microchip datasheet (DS39940), the CTMU enables capacitance-based measurements (e.g., water presence, flow), and the hardware crypto engine plus true RNG secure stored telemetry against tampering in unattended deployments.
おすすめ
Battery-Powered Sensor Nodes
Battery-powered wireless sensor nodes benefit from the PIC24FJ128GB106-I/PT's XLP technology, which draws under 100 nA in Deep Sleep with RTCC running. Per Microchip datasheet (DS39940), multiple wake sources (RTCC alarm, WDT, external interrupt, USB attach) allow the node to spend most of its life asleep and wake briefly to measure and transmit. The 16 KB RAM buffers sensor bursts, while four UART channels and three SPI buses support concurrent radios (Sub-GHz, BLE co-processor). Industrial temperature grade and 2.0 V to 3.6 V operation directly support 2xAA or coin-cell battery chemistries.

設計ノート
Estimated: at 32 MHz / 3.3 V / full peripherals active, core current draw is approximately 24 mA per Microchip datasheet (DS39940) typical numbers; add USB transceiver contribution during active USB transactions. For battery designs, use Deep Sleep (<100 nA) with RTCC wake to keep average system current in the single-digit microamp range. Place a 4.7 uF to 10 uF bulk decoupling capacitor on each VDD pin pair (multiple VDD/VSS pins exist on the TQFP-64) within 5 mm of the MCU.
Per Microchip datasheet (DS39940), the USB D+ and D- traces must be 90 ohm differential, length-matched within 150 mil, and routed over a continuous ground plane with no splits. Keep the VUSB3V3 decoupling capacitor (4.7 uF recommended) within 3 mm of pin 14 to ensure stable USB transceiver operation. Avoid routing digital switching signals across the USB differential pair, and place the 24 MHz crystal (if not using internal oscillator) within 1 cm of the OSC1/OSC2 pins with guard traces.
Do not leave the VBUS pin floating when USB host is unused - tie to VDD through a 100 kohm resistor to disable USB attach detection and prevent false interrupts. Avoid driving the MCLR pin low during normal operation unless intentionally resetting; configure it as a digital input with internal pull-up if unused. When migrating from PIC24FJ128GA106 (device-only) to PIC24FJ128GB106 (OTG), verify your firmware initializes the OTG controller and provides the 4.7 uF capacitor on VUSB3V3 to avoid USB enumeration failure.
Use Peripheral Pin Select (PPS) to remap peripheral functions to convenient physical pins before PCB layout finalization - changing PPS assignments after layout requires no PCB rework but does require recompilation. Per Microchip datasheet (DS39940), reserve PPS remapping room by keeping related pin groups (e.g., UART RX/TX pairs) on adjacent physical pins. Place the ICSP programming header (PGECx/PGEDx) in a footprint accessible by an in-circuit programmer without removing the MCU from board.
Estimated: USB Full-Speed signaling edge rates require 90 ohm differential impedance with 30 mil trace width and 8 mil gap on standard 4-layer FR-4 (1.6 mm). For Peripheral Pin Select outputs driving external logic, limit trace length to under 50 mm when driving signals above 10 MHz to avoid ringing. Place series termination resistors (22-33 ohm) on high-speed PWM or SPI outputs driving capacitive loads outside the MCU's local decoupling area.
