PIC24FJ192GB110-I/PT Présentation
A 16-bit microcontroller is a microprocessor core with a 16-bit data path, 16-bit registers, and a 16-bit ALU, providing a higher performance ceiling than 8-bit cores while remaining significantly simpler and lower-power than 32-bit Cortex-M devices. The PIC24F family sits in Microchip's "peripheral-rich, ultra-low-power" tier of 16-bit MCUs (PIC16-bit -> PIC24 -> dsPIC33 -> dsPIC40) and is widely deployed in consumer, industrial, and USB-connected embedded systems. The PIC24FJ192GB110 variant adds a USB 2.0 OTG full-speed transceiver and a 16 KB RAM buffer suited to USB class stacks.
Key features include 192 KB Flash (65.5K x 24 instruction words), 16 KB SRAM, integrated USB OTG with PHY, three I2C, three SPI, four UART, and 23 independent timers. Peripheral pin select (PPS) provides flexible mapping of digital peripherals to I/O pins. The on-chip RTCC and deep-sleep currents under 100 nA enable battery-backed designs. The 100-pin TQFP package exposes up to 84 general-purpose I/O pins.
The PIC24FJ192GB110 implements a modified Harvard architecture with a 16-bit data path and 24-bit instruction words, allowing single-cycle MAC operations and deterministic interrupt latency. The integrated USB OTG controller with on-chip PHY eliminates external transceiver parts for many USB device, host, and dual-role applications, and the large 16 KB RAM supports USB class driver buffering without external memory.
Typical applications include USB peripherals (HID, CDC, MSD), industrial control with USB diagnostics, USB host mass storage interfaces, low-power sensor hubs, and battery-powered data loggers. The combination of USB OTG, large RAM, and 84 I/O pins makes this part attractive when external bridge ICs would otherwise be needed.
When designing with this device, ensure the 2.0-3.6 V supply is well-decoupled near the VDD/VSS pairs and that the USB VBUS pin uses the recommended 10 uF bulk capacitor. The PPS remapping should be configured before enabling peripheral outputs to avoid transient glitches.

Applications typiques
PIC24FJ192GB110-I/PT convient pour 6 applications: USB Human Interface Device (HID) Peripherals, USB CDC Virtual COM Port Bridges, USB Mass Storage Device (MSD) Data Loggers, USB Host with Mass Storage Interface, Low-Power Sensor Hubs with USB Diagnostics, Industrial Control with USB Field Updates.
USB Human Interface Device (HID) Peripherals
The PIC24FJ192GB110-I/PT is well suited for USB HID peripherals such as keyboards, mice, game controllers, and custom input devices. The integrated USB 2.0 full-speed OTG PHY with on-chip transceiver eliminates external bridge ICs, reducing BOM cost and PCB area. The 16 KB RAM is large enough to host the USB HID class stack plus application runtime memory for key debouncing, macro handling, and LED animation without external SRAM. The PIC24F core at 32 MHz / 16 MIPS provides headroom for HID report processing, NKRO logic, and wireless dongle interfaces, while the four UARTs can drive external BLE or 2.4 GHz modules. Deep-sleep current under 100 nA supports battery-powered wireless HID designs that wake on interrupt.
Recommandé
USB CDC Virtual COM Port Bridges
Industrial and embedded designs often need a USB-to-UART bridge; PIC24FJ192GB110-I/PT handles CDC class natively over its USB OTG peripheral and exposes four hardware UARTs to downstream MCUs or sensors. The 192 KB Flash and 16 KB RAM allow a full CDC stack plus command parser and trace logging on-chip. Operating voltage 2.0-3.6 V supports both battery-powered and 3.3 V industrial rails, and the -40C to +85C industrial temperature range ensures operation in factory and outdoor enclosures. Compared with discrete bridge chips such as FT232R, this approach adds a programmable MCU with GPIOs and timers at similar cost, enabling custom vendor protocols on the UART side.
Recommandé
USB Mass Storage Device (MSD) Data Loggers
The PIC24FJ192GB110-I/PT supports USB MSD class to expose SD cards or onboard Flash as removable storage for portable data loggers and instrumentation recorders. With 16 KB RAM, the MCU can buffer sector writes, manage FAT file allocation tables, and timestamp samples with the on-chip RTCC. The 23 independent timers handle multiple sample-rate channels simultaneously, while the deep-sleep current under 100 nA keeps quiescent drain low between log events. The integrated USB OTG PHY lets the same port serve as both host (reading external USB sticks) and device (PC downloading logs), and the 100-pin TQFP exposes enough I/O for SPI-driven SD cards, ADC inputs, and status displays.
Recommandé
USB Host with Mass Storage Interface
Acting as a USB host, PIC24FJ192GB110-I/PT can interface to USB flash drives, keyboards, and printers in embedded kiosks, industrial terminals, and test equipment. The integrated OTG PHY plus host-capable controller eliminates external hub ICs in many single-port designs. The 192 KB Flash accommodates USB host class drivers (HID, Mass Storage) and application logic for ticket printing, kiosk I/O, or test sequencing. The 84 I/O pins handle LCDs, keypads, sensors, and motor controls around the host interface, and the four UARTs provide debug and external device connectivity without sacrificing host operation.
Recommandé
Low-Power Sensor Hubs with USB Diagnostics
Battery-powered sensor hubs benefit from the PIC24FJ192GB110-I/PT deep-sleep current under 100 nA combined with on-chip RTCC, multiple I2C/SPI peripherals, and a USB port for diagnostics and firmware updates. The 16 KB RAM buffers sensor frames between wake cycles, while the 192 KB Flash supports sensor fusion, USB CDC diagnostic logs, and a USB DFU bootloader for field updates. The 23 timers handle multiple sensor sample rates from sub-Hz temperature to kHz-class vibration channels, and the 100-pin TQFP package supports up to 84 I/O for sensor matrix and external ADC interfaces.
Recommandé
Industrial Control with USB Field Updates
The PIC24FJ192GB110-I/PT fits industrial control nodes that need USB for firmware updates, configuration export, and diagnostics without an external bridge IC. With 23 timers and 4 UARTs, the MCU can drive PWM outputs, quadrature decoders, and Modbus RTU links while presenting a USB CDC/MSD port to a service laptop. The -40C to +85C industrial temperature range covers factory floor enclosures, and the 100-pin TQFP exposes 84 I/O for opto-isolated inputs, relay drivers, and analog sensors. The 192 KB Flash supports a dual-image bootloader (active + upgrade) for safe USB-based field updates.

Notes de conception
Decouple every VDD/VSS pair with 100 nF ceramic placed within 3 mm of each pair, plus a single 4.7 uF bulk on the main VDD rail. The USB VUSB3V3 pin (pin 41) requires its own 10 uF bulk and a 100 nF decoupling cap per the Microchip datasheet. Avoid routing digital return currents through the analog AVSS/AVDD pair to keep ADC noise low. Estimated: total decoupling budget is ~7 small-value ceramic caps plus 1-2 bulk caps.
The 100-pin TQFP has a theta_JA in the 50-60 C/W range on a standard 2-layer JEDEC board, rising to ~70 C/W on low-copper designs. The PIC24FJ192GB110 draws low current in deep sleep (under 100 nA) and modest active current at 32 MHz, so thermal rise is rarely a problem in USB applications. However, ensure the PCB has at least 1 oz copper on VDD/VSS planes to spread heat from higher duty-cycle use cases.
Route USB D+ and D- as a 90-ohm differential pair with trace lengths matched within 150 mil per the USB 2.0 full-speed spec. Keep the pair away from switching signals and clock traces to maintain signal integrity. Place the USB connector within 25 mm of the D+/D- pins to minimize stub length and EMI, and route the VBUS sense line with the same care as a signal trace.
Do not omit the VUSB3V3 bulk capacitor; USB enumeration fails without proper USB transceiver supply. Configure Peripheral Pin Select (PPS) registers before enabling peripheral outputs to avoid transient glitches on shared pins. Always include the MCLR pull-up and decoupling per the Microchip datasheet to guarantee proper reset behavior in noisy environments.
