PIC24FJ192GB110T-I/PF - 16-bit 32MHz USB OTG MCU, 192KB Flash | Microchip
MPN: PIC24FJ192GB110T-I/PF ✓ نشطPIC24FJ192GB110T-I/PF نظرة عامة
A PIC24F microcontroller is a 16-bit flash MCU family from Microchip that sits between the 8-bit PIC16/PIC18 families and the 16-bit dsPIC/PIC32 families. It is built on a Modified Harvard architecture with separate program and data buses, enabling single-cycle instruction fetch with data access, while sharing a unified 16-bit instruction set across the family. PIC24F parts are positioned for low-power (<100 nA standby current) embedded designs that need richer peripherals than an 8-bit MCU can deliver but do not require a digital signal processor. Within Microchip's portfolio, PIC24FJ192GB110 belongs to the PIC24F USB family, which adds an integrated USB 2.0 full-speed On-The-Go transceiver to the standard PIC24F feature set.
Key features include USB OTG with integrated transceiver, 16 MIPS performance at 32 MHz, low-power nanoWatt XLP technology for <100 nA standby current, and 84 remappable I/O pins via the Peripheral Pin Select (PPS) subsystem. The 16 KB RAM and 192 KB Flash support buffering and large protocol stacks, while 3x I2C, 3x SPI, 4x UART, and 23 timers allow parallel connectivity and control tasks without external peripherals. Real-time clock, comparators, 10-bit ADC (16 channels at 500 ksps), and 16-bit timers reduce external analog and timing component counts.
Architecture depth: the device uses a 16-bit data path with separate 24-bit program and 16-bit data buses for the Modified Harvard core, and the C compiler (MPLAB XC16) maps efficiently onto the 16-element working register array. Hardware DSP-like acceleration is provided by a 17-bit x 17-bit single-cycle multiplier and a 16/32-bit hardware divider. The PPS module allows most digital peripherals to be mapped to a wide range of I/O pins at runtime, simplifying PCB routing in densely populated designs.
Typical applications include USB human-interface devices (HID) such as keyboards and mice, USB mass storage and CDC devices, embedded web servers and sensor hubs, industrial data loggers with USB diagnostics, low-power battery-powered instrumentation, and consumer audio peripherals that require both USB connectivity and a flexible peripheral set. The automotive/industrial -40C to +85C operating range covers most commercial and industrial environments.
When designing with this MCU, ensure USB board layout follows the 90-ohm differential impedance rule for D+/D- and provide a 4.7 kV ESD-protected connector. Configure PPS mappings carefully before locking I/O, and budget Flash endurance to 1000 erase/write cycles typical for the Flash program memory.

التطبيقات النموذجية
PIC24FJ192GB110T-I/PF مناسب لـ 6 التطبيقs: USB HID Keyboard and Mouse, USB Mass Storage and CDC Devices, Industrial Data Logger with USB Diagnostics, Embedded Web Server / Sensor Hub, Consumer Audio Peripheral with USB, Battery-Powered Portable Instrument.
USB HID Keyboard and Mouse
The PIC24FJ192GB110T-I/PF is well-matched to USB HID keyboards and pointing devices. Its integrated USB 2.0 full-speed OTG controller eliminates the need for an external PHY, reducing BOM cost and PCB area. With 84 remappable I/O pins via Peripheral Pin Select and 192 KB Flash, designers can implement large key scan matrices and complex gesture firmware without external I/O expanders. The 16 KB RAM is sufficient for key rollover buffers and HID report queues, while the 16 MIPS core keeps USB polling latency low. Power comes directly from the USB 5V rail through a 3.3V regulator, and the <100 nA standby current in nanoWatt XLP mode extends battery life in wireless HID dongles.

USB Mass Storage and CDC Devices
The PIC24FJ192GB110T-I/PF supports USB Mass Storage (MSD) and Communication Device Class (CDC) applications such as portable data loggers and USB-to-UART bridges. The 192 KB Flash accommodates the MSD bootloader plus FAT12/16 file-system code, while 16 KB RAM holds sector buffers for typical 512-byte transfers. Four UART channels enable CDC multi-port bridges, and 23 timers provide precise USB frame timing and baud-rate generation. Compared to 8-bit alternatives, the 16-bit core at 16 MIPS cuts command parsing latency, improving throughput on bulk-only mass-storage transfers. The integrated OTG controller supports both device and limited host roles for flexible peripheral attachment.

Industrial Data Logger with USB Diagnostics
In industrial data-logging applications, the PIC24FJ192GB110T-I/PF combines robust peripherals with USB diagnostics. The 16-channel 10-bit ADC at 500 ksps captures multiple analog sensor inputs simultaneously, while 16 KB RAM buffers time-stamped samples before batch transfer over USB. The 3x I2C and 3x SPI buses connect to digital sensors and external Flash for long-term storage, and 23 timers handle precise sampling intervals without software overhead. Operating from 2.0 V to 3.6 V lets designers run directly from battery stacks with USB charging managed by the integrated OTG controller. The -40C to +85C industrial temperature range ensures operation in factory-floor enclosures.

Embedded Web Server / Sensor Hub
The PIC24FJ192GB110T-I/PF can host lightweight TCP/IP stacks such as Microchip's MLA TCP/IP for embedded web-server and sensor-hub roles when paired with an external Ethernet controller. Its 192 KB Flash fits a stripped-down HTTP server with custom CGI handlers, and 16 KB RAM is enough for socket buffers when data flow is constrained. Peripheral Pin Select allows flexible SPI/UART routing to sensors and to an ENC28J60 or similar Ethernet MAC, simplifying board layout. The 16 MIPS core handles HTTP request parsing with headroom for periodic sensor sampling, while nanoWatt XLP modes cut idle power between requests. Industrial temperature rating ensures reliable operation in unattended network-attached sensors.

Consumer Audio Peripheral with USB
USB audio peripherals such as headsets, microphones, and USB speakers benefit from the PIC24FJ192GB110T-I/PF's integrated USB OTG and 16 MIPS core. The device handles USB Audio Class 1.0 descriptors and stream management without external DSP, while 16 KB RAM buffers audio packets. 3x I2C buses can configure external audio codecs (e.g., S/PDIF transceivers, DACs), and 4x UARTs support auxiliary control channels for buttons and indicators. Compared to 8-bit alternatives, the 16-bit core processes USB feedback packets and sample-rate matching with low jitter. Operating from 3.3V derived from the USB 5V rail simplifies power architecture.

Battery-Powered Portable Instrument
Battery-powered portable instruments benefit from the PIC24FJ192GB110T-I/PF's nanoWatt XLP technology with standby current below 100 nA. The 2.0 V to 3.6 V supply range allows direct operation from a single Li-ion or two AA cells without boost regulators, and the integrated USB OTG controller supports both charging and data exchange on the same port. 192 KB Flash holds calibration tables and firmware, while 16 KB RAM supports measurement buffering between sleep cycles. The 16 MIPS core wakes from sleep quickly via the 8 MHz internal oscillator with 4x PLL, capturing sensor bursts efficiently. Industrial temperature rating ensures reliable cold-start operation outdoors.

ملاحظات التصميم
Route USB D+ and D- as a 90-ohm differential pair with matched length (within 2 mm) on the top layer, keeping them away from clocks and switching signals. Place the VBUS voltage-divider resistors within 5 mm of the VBUS pin and provide a 4.7 uF bulk capacitor plus 0.1 uF decoupling near the MCU VDD pins. For OTG host mode, allocate space for the VBUS charge-pump circuitry. The 14x14 mm TQFP (PF) lands do not match 12x12 mm PT footprints - verify PCB land pattern before sourcing alternatives.
PIC24FJ192GB110T-I/PF operates from 2.0 V to 3.6 V on VDD, with separate AVDD/AVSS rails for the 10-bit ADC. Estimate: at 32 MHz / 16 MIPS, active current is approximately 22 mA typical, while nanoWatt XLP sleep drops to <100 nA. Add a 10 uF bulk + 0.1 uF ceramic near each VDD/VSS pair, plus a ferrite bead between digital VDD and analog AVDD if ADC performance is critical. For USB bus-powered designs, route VBUS through a power switch (e.g., MIC2026) with proper decoupling.
When using Peripheral Pin Select (PPS), lock the I/O mappings before committing firmware to production - unlocked PPS can lead to configuration mismatches across boards. Configure MCLR as a digital input only if reset is not needed externally; otherwise tie through a 10 kohm pull-up to VDD. The Flash program memory endurance is rated at 1000 erase/write cycles typical, so use external EEPROM (e.g., 24LC256) for frequently updated user data. Always unlock the configuration word region before programming, and respect the JTAG/SWD boundary scan (BSDL) configuration when designing test fixtures.
