PIC24FJ192GB110T-I/PT Overview
Background context: A 16-bit microcontroller is an embedded processor with a 16-bit data path and instruction set, sitting architecturally between 8-bit MCUs (lower cost, simpler peripherals) and 32-bit MCUs (higher performance, more memory). Within the PIC family hierarchy, the PIC24F sits below the dsPIC33 and PIC32 families. The "FJ" prefix denotes Flash program memory with the nanoWatt XLP low-power technology; "GB" indicates integrated USB OTG with on-chip transceiver. PIC24F MCUs are widely used in human-interface devices, USB peripherals, and industrial control where USB connectivity plus low standby current (<100 nA) matter.
Key features include 192 KB Flash (65.5K x 24), 16 KB RAM, integrated USB 2.0 OTG with on-chip transceiver, three I²C, three SPI, four UART ports, 23 independent timers, and nanoWatt XLP technology with sub-100 nA standby current. The 100-pin TQFP (PT) package exposes all of these peripherals plus a parallel master port for external memory or graphics interfacing.
At 32 MHz core speed the device delivers approximately 16 MIPS of throughput, with instruction cycles that complete in two clock periods. The PIC24F core uses a 16-bit modified Harvard architecture with a hardware multiplier for DSP-like operations. Power management includes multiple idle and sleep modes (Sleep, Idle, Doze, Alternate Run), a real-time clock calendar (RTCC) with on-chip 32 kHz oscillator, and integrated LDO regulator for single 2.0-3.6 V supply operation.
Typical applications include USB peripherals such as mass storage, HID, CDC, and audio class devices; industrial data loggers; medical instrumentation; graphic LCD/OLED controllers with the parallel master port; and battery-powered sensors needing <100 nA standby. Designers frequently pair the PIC24FJ192GB110 with external PHY-less USB connectors and FTDI-style serial bridges, or use it as a USB host for mass storage.
Design consideration: The PIC24FJ192GB110 family requires careful attention to USB bus impedance (90 ohm differential) on D+/D- traces and decoupling capacitor placement near the VUSB3V3 pin. The 100-pin TQFP footprint (12x12 mm) is large enough to support four-layer PCB routing; however, leaving the parallel master port unused frees significant board space on simpler designs.

Typical Applications
PIC24FJ192GB110T-I/PT is suitable for 7 applications: USB Human Interface Device (HID) Peripherals, USB Audio Class Devices, Industrial Data Loggers, Graphic LCD / OLED Display Controllers, Medical Instrumentation, Battery-Powered USB Sensors, USB Host Mass Storage Devices.
USB Human Interface Device (HID) Peripherals
The PIC24FJ192GB110T-I/PT is a strong fit for USB HID peripherals because the integrated USB 2.0 OTG transceiver eliminates external PHY cost while the 192 KB Flash comfortably holds HID class descriptors plus application code. The 32 MHz core delivers 16 MIPS, sufficient to poll key matrices, encode HID reports, and run USB protocol stack in parallel without timing issues. With 16 KB RAM, designers can buffer multi-endpoint HID data (keyboard + mouse + consumer control composite device) without external memory. The 100-pin TQFP exposes enough I/O for matrix scanning, LED indicators, and serial debugging via UART. Compared to discrete USB implementations using FTDI bridges, this single-chip solution reduces BOM cost, PCB area, and firmware complexity.
Recommended
USB Audio Class Devices
The PIC24FJ192GB110T-I/PT supports USB Audio Class 1.0/2.0 device operation, making it well suited to USB headsets, microphones, and audio interfaces. The on-chip USB OTG transceiver handles full-speed (12 Mbps) USB audio streams without external components, while the 192 KB Flash stores USB audio stack plus DSP-like audio processing routines. The 16 KB RAM is sufficient to buffer small audio packets (~10 ms latency at 48 kHz mono). Hardware peripherals - three SPI ports, three I²C, four UARTs - let designers integrate external audio codecs (e.g., S/PDIF transmitters, DACs) and configuration EEPROMs alongside USB. Power consumption is moderate; designers can disable the PLL during idle audio streams to reduce current draw.
Recommended
Industrial Data Loggers
The PIC24FJ192GB110T-I/PT is well matched to industrial data loggers because the 192 KB Flash and 16 KB RAM allow large rolling buffers, while the four UART ports support simultaneous multi-sensor interfaces (RS-232, RS-485, GPS, Bluetooth SPP). The 16-channel 10-bit ADC handles analog transducer inputs directly, and the RTCC with on-chip 32 kHz oscillator timestamps every log entry. The -40°C to +85°C industrial temperature grade (I suffix) ensures operation in harsh factory environments. nanoWatt XLP technology with sub-100 nA standby lets battery-powered remote loggers run for years between battery replacements. The 100-pin TQFP provides generous I/O for indicator LEDs, pushbuttons, and SD card interfaces via PMP or SPI.
Recommended
Graphic LCD / OLED Display Controllers
The PIC24FJ192GB110T-I/PT drives graphic LCD and OLED displays via its Parallel Master Port (PMP), which can directly interface with 8080/6800-style display controllers at high throughput. The 192 KB Flash stores frame-buffer manipulation libraries and font tables, while the 16 KB RAM acts as a partial frame buffer for full-color QVGA displays. The 32 MHz core can refresh displays fast enough to avoid flicker on 320x240 panels. Three SPI ports support serial OLED displays, and the RTCC can schedule automatic brightness adjustments based on time of day. Designers building human-machine interfaces (HMIs) benefit from the 100-pin package's abundant GPIO for touch-panel scanning and backlight control.
Recommended
Medical Instrumentation
The PIC24FJ192GB110T-I/PT suits medical instrumentation such as portable glucose meters, pulse oximeters, and USB-connected diagnostic tools. The 16-bit core delivers sufficient precision for signal processing on biomedical analog signals (filtered/amplified photoplethysmogram, impedance, etc.) without external DSPs. The USB OTG interface enables direct tethering to PCs for data upload or battery charging (USB CDC + battery charger IC). nanoWatt XLP technology with <100 nA standby extends battery life for patient-worn devices, while the 192 KB Flash fits BLE/USB stacks plus medical firmware. The industrial temperature grade ensures reliability across hospital and home environments.
Recommended
Battery-Powered USB Sensors
The PIC24FJ192GB110T-I/PT is ideal for battery-powered USB sensors that spend most of their time in standby. nanoWatt XLP technology holds standby current below 100 nA with RTCC running, allowing coin-cell-powered sensors to last multiple years. When a host PC connects via USB, the on-chip OTG transceiver negotiates enumeration within milliseconds and wakes the core from Sleep. The 192 KB Flash easily stores USB HID class stacks plus sensor-calibration data, while 16 KB RAM is ample for sample buffering. Multiple UARTs, SPIs, and I²C ports support a wide range of digital sensors (temperature, pressure, IMU, gas). The 100-pin TQFP exposes sufficient I/O for sensor multiplexing and indicator LEDs.
Recommended
USB Host Mass Storage Devices
The PIC24FJ192GB110T-I/PT functions as a USB host controller for embedded mass-storage products such as portable media players or data copiers. The on-chip OTG controller can act as a USB host, and the 192 KB Flash accommodates FAT file-system libraries plus USB host stack. The 16 KB RAM is sufficient to buffer small file transfers; PMP provides a fast interface to external NAND or SD cards. Designers can implement multi-LUN access for multiple attached USB sticks. The 100-pin TQFP exposes the necessary I/O for power-management control of USB VBUS and overcurrent detection, plus UART/SPI for user-interface panels.

Design Notes
Route the USB D+/D- traces as a 90 ohm differential pair with characteristic impedance matched to the USB spec. Keep the traces short, length-matched within 150 mil, and away from switching signals or oscillators. Place the VUSB3V3 decoupling capacitor (typically 0.1uF ceramic) within 1 mm of the VUSB3V3 pin. Connect the VBUS pin through a divider to a remappable I/O for host-detection logic. Maintain a continuous ground plane under the USB traces for return current.
The PIC24FJ192GB110T-I/PT operates from a single 2.0V to 3.6V supply; place 0.1uF ceramic decoupling capacitors close to every VDD pin (multiple VDD pins exist on the 100-pin TQFP). Add a bulk 10uF tantalum or ceramic capacitor near the IC. The USB transceiver requires the dedicated VUSB3V3 rail - either power it from the main 3.3V rail or from the internal LDO via proper filtering. Keep analog and digital supplies separated at the IC and join them at a single point at the regulator output to minimize ADC noise coupling.
Do not omit the MCLR pull-up resistor (typically 10 kohm to VDD); without it the device may fail to start up or be stuck in reset. The PGED1/PGEC1 and PGED2/PGEC2 pins are shared with general I/O; if used for ICSP debugging, do not place loading components on these lines. When using nanoWatt XLP Sleep mode, ensure the RTCC is configured correctly with a 32.768 kHz crystal on SOSCI/SOSCO, or the low-power timekeeping will be inaccurate. The USB module requires the PLL to be enabled at 48 MHz for proper operation - failing to configure the PLL will result in USB enumeration failures.
The 100-pin TQFP (12x12 mm body) package requires four-layer PCB routing for clean signal integrity on the parallel master port (PMP) and USB differential pair. Use a 0.5 mm pitch land pattern with 0.4 mm wide traces and 0.2 mm spacing. Keep crystal traces (OSC1/OSC2, SOSCI/SOSCO) short and surrounded by ground pour. Place the ICSP programming connector footprint at the board edge for easy in-circuit debugging. Allow room for the optional external 32.768 kHz crystal and load capacitors for RTCC applications.
Compliance Information
