PIC24FJ192GB106-I/MR Présentation
A microcontroller (MCU) is an integrated circuit that combines a CPU core, program and data memory, plus configurable peripherals on a single silicon die. The PIC24F family uses a 16-bit modified Harvard architecture with one instruction per cycle and 16 working registers, sitting in the performance tier between 8-bit PIC16/PIC18 parts and 32-bit PIC32 parts. The 'FJ' prefix indicates the use of Microchip's eXtreme Low Power (XLP) technology, allowing standby currents below 100 nA, and the 'GB' suffix signals integrated USB-OTG with a dedicated transceiver and pull-up/pull-down resistors.
Key specifications include 192KB (65.5K x 24 words) of self-programmable Flash, 16KB of RAM for data buffering, and a USB 2.0 full-speed OTG controller with internal transceiver. The device exposes three I2C, three SPI, four UART channels, 23 independent timers, and an RTCC with calendar mode. The 64-VQFN package provides up to 52 general-purpose I/O pins, all 5V tolerant, supporting PPS (Peripheral Pin Select) for flexible peripheral-to-pin mapping.
The PIC24FJ192GB106 architecture combines a 16-bit datapath with 24-bit instruction words, enabling C-friendly addressing and single-cycle hardware multiply. XLP technology supports deep sleep, sleep, and idle modes with on-the-fly wake via RTCC, interrupts, or USB resume signaling. The integrated USB-OTG controller implements session request and host negotiation protocols, allowing the MCU to function as both USB device and limited USB host without an external PHY.
Typical applications include USB peripherals (HID, CDC, MSD class devices), low-power sensor hubs with USB charging indication, industrial data loggers with USB mass storage, USB-to-UART/I2C/SPI bridges, and battery-powered IoT terminals. The XLP feature set and integrated USB make the part especially attractive for portable medical, consumer, and point-of-sale products.
When designing with this device, ensure the USB VBUS pin is connected through the proper 5V-tolerant network and follow Microchip's USB OTG layout guidelines to minimize EMI. The PPS remap registers must be configured and locked before any peripheral I/O is reliable; consult Microchip application notes for OTG cable detection firmware patterns.

Applications typiques
PIC24FJ192GB106-I/MR convient pour 7 applications: USB HID Peripheral (Keyboard, Mouse, Custom HID), USB to UART / SPI / I2C Bridge Dongle, USB Mass Storage Device (Data Logger), Portable Medical / Health Monitor with USB Charging, Industrial Sensor Hub with USB Diagnostics, USB-OTG Tablet Accessory / Stylus Charger, USB-Connected Lighting Controller (DMX / WS2812).
USB HID Peripheral (Keyboard, Mouse, Custom HID)
The PIC24FJ192GB106-I/MR is purpose-built for USB HID class devices, with its integrated USB 2.0 full-speed OTG controller eliminating the need for an external PHY. Its 16 MIPS performance and Microchip's free USB stack deliver sub-millisecond HID polling rates for keyboards, mice, game controllers, and custom-HID industrial input panels. 192KB Flash comfortably fits HID bootloaders plus application firmware, while 16KB RAM supports HID report buffers and command parsing. The PPS peripheral mapping lets engineers route HID interrupt pins to any I/O, simplifying PCB layout in space-constrained enclosures.
Recommandé
USB to UART / SPI / I2C Bridge Dongle
With three I2C, three SPI, and four UART peripherals, the PIC24FJ192GB106-I/MR naturally serves as a multi-protocol USB bridge dongle that exposes host-side serial buses through a single USB CDC or vendor-class endpoint. The 32 MHz core and 192KB Flash allow firmware to multiplex multiple bridge channels simultaneously while running a USB composite stack. Industrial-grade -40C to +85C operation supports field-service tooling, lab instrumentation, and factory programming fixtures. The integrated USB OTG pull-up/pull-down resistors further reduce the bridge dongle BOM to essentially just the MCU and connectors.
Recommandé
USB Mass Storage Device (Data Logger)
The PIC24FJ192GB106-I/MR supports USB mass storage class device firmware that emulates an external drive backed by SPI/SD card or internal Flash, ideal for portable data loggers in industrial monitoring. Microchip's USB MSD stack fits in under 32KB, leaving more than 130KB for application code, sensor drivers, and wear-leveling algorithms. XLP standby currents below 100nA enable months-long battery life in field-deployable loggers, with USB re-enumeration waking the MCU for file transfer. The 52 GPIO pins support multiple sensor buses, RTCC time-stamping, and status LEDs without external I/O expanders.
Recommandé
Portable Medical / Health Monitor with USB Charging
Medical and consumer health devices require low-power sleep with periodic wake, USB device charging indication, and reliable sensor readout. The PIC24FJ192GB106-I/MR's XLP standby below 100nA extends battery life between measurement cycles, while its integrated USB OTG enables direct charging and data sync without external interface chips. The 16-bit ADC, ample RAM for buffering samples, and CTMU peripheral provide accurate sensor measurements for pulse oximetry, blood pressure cuffs, and portable ECG patches. Industrial temperature range supports clinical environment operation.
Recommandé
Industrial Sensor Hub with USB Diagnostics
Industrial sensors that aggregate analog/digital inputs and expose real-time diagnostics over USB benefit from the PIC24FJ192GB106-I/MR's 5x16-bit timers, 3xSPI for digital sensors, and 23 independent timer instances. Engineering teams use the device's PPS flexibility to map I2C, SPI, and UART pins around physical connectors without redesign. The 192KB Flash accommodates Modbus, OPC UA, or USB vendor-class stacks for diagnostics, while XLP modes reduce quiescent draw in intermittently sampled applications. -40C to +85C operation covers factory floor temperature ranges.
Recommandé
USB-OTG Tablet Accessory / Stylus Charger
USB OTG host role allows the PIC24FJ192GB106-I/MR to power and charge external accessories - such as active stylii, USB headsets, or barcode scanners - from a tablet's micro-USB port. The integrated session-request-protocol and host-negotiation-protocol hardware manages VBUS drive without external charge-pump components. 192KB Flash is sufficient for HID + vendor-class composite stacks plus battery-charging spec (BC1.2) detection logic. The 64-VQFN 9x9mm package fits inside ultra-thin tablet accessories while exposing 52 GPIOs for accessory-side sensors and controls.
Recommandé
USB-Connected Lighting Controller (DMX / WS2812)
Architectural and stage lighting controllers increasingly expose a USB host interface for PC-based configuration while driving LED strips via SPI or DMA-driven bitbang. The PIC24FJ192GB106-I/MR's 16 MIPS CPU easily generates WS2812 800kbps timing on any GPIO via the SPI peripheral, while its USB CDC/vender-class endpoint receives DMX-over-USB streams. The 192KB Flash holds personality libraries for multiple fixture types, and 16KB RAM buffers full DMX universes. -40C to +85C ensures operation in hot stage-lighting enclosures.

Notes de conception
The PIC24FJ192GB106-I/MR requires a stable 2.0V-3.6V VDD supply and a separate 3.3V VUSB rail for the USB transceiver. Use a low-noise LDO such as MIC5504-3.3YM5-TR to derive VDD from the USB VBUS 5V, and add a 100nF decoupling cap on every VDD/VSS pair plus 10uF bulk capacitance on the main rail. The XLP modes (Sleep, Deep Sleep) keep standby below 100nA but require careful peripheral disable sequences in firmware to avoid phantom current draws.
Route USB D+ and D- as a 90-ohm differential pair with continuous ground reference on the layer beneath, keeping trace length under 25mm where possible. Place the 15k pull-down on D- to ground at the connector side, and the 1.5k pull-up on D+ to VUSB switched via software for device-connect signaling. The VQFN-64 thermal pad must be soldered to a continuous ground plane with at least 8 thermal vias for heat dissipation.
Failure to lock the PPS register (IOLOCK) via the OSCCON unlock sequence leaves peripheral mappings volatile after a watchdog reset - symptoms include peripherals stopping after brown-out recovery. Also, the RTCC requires the SOSC crystal on pins RA4/RA4 or it silently runs from internal LPRC with reduced accuracy. For USB OTG host role, VBUS must be capable of sourcing 100mA minimum and a soft-start circuit is recommended to prevent inrush current spikes.
