PIC24FJ128GB110T-I/PT Обзор
A 16-bit microcontroller (MCU) is a programmable processor with internal Flash, RAM, and peripherals integrated on a single die. Within the embedded taxonomy, the PIC24FJ family sits between 8-bit PIC16/PIC18 MCUs and 32-bit PIC32 ARM Cortex parts. The PIC24F line emphasizes low-power eXtreme Low Power (XLP) variants with the Harvard architecture, providing deterministic instruction cycles for real-time control. USB OTG enables the device to act as both USB host and peripheral without an external PHY, which is uncommon in this price/performance tier.
Key features include an 8 MHz internal oscillator with 4x PLL (yielding 32 MHz core), 17-bit single-cycle hardware multiplier, 16-bit hardware divider, and C compiler-optimized instruction set. The CTMU module supports touch sensing, mTouch capacitive buttons, and time-of-flight measurement, while the PMP/EPSP modules drive parallel displays. Five 16-bit timers/counters, four UARTs, two SPI, and two I2C peripherals cover typical wired connectivity.
The architecture combines modified Harvard separation of program and data buses with a 16-bit working register array, delivering up to 16 MIPS while drawing microamp sleep currents. The integrated USB OTG PHY supports full-speed (12 Mbps) host and device roles, plus low-speed (1.5 Mbps) device mode, with internal pull-up/pull-down resistors selectable by firmware.
Typical applications include USB peripherals (HID, CDC, MSD), industrial control with capacitive touch HMIs, portable data loggers with RTC, embedded host products (USB flash drive readers, keyboards), and medical monitoring devices needing low sleep current. The wide 2.0V-3.6V supply range also supports battery-powered IoT sensor nodes.
Design with this MCU by allocating a minimum 1 µF bulk decoupling capacitor on VDD and 100 nF on each AVDD pair; place the 32 kHz crystal within 1 cm of SOSCO/SOSCI to minimize RTC drift. USB D+/D- traces must be 90 ohm differential, length-matched within 2 mm, and routed over a continuous ground plane. The 'T' suffix indicates Tape & Reel packaging; the operating range is industrial -40C to +85C (I-grade).

USB HID Peripheral Device
The PIC24FJ128GB110T-I/PT excels in USB Human Interface Device (HID) peripherals such as keyboards, mice, game controllers, and custom input devices. The integrated USB 2.0 Full-Speed OTG controller with on-chip PHY eliminates external transceiver components, reducing BOM cost by approximately $0.50-$1.00 per unit. With 128KB Flash and 16KB RAM, the MCU runs Microchip's MLA USB device stack plus HID class drivers with room for application logic. The 16 MIPS performance comfortably handles HID report generation at the 1000 Hz polling rate with substantial CPU headroom for debouncing, key matrix scanning, and LED effects. Per Microchip datasheet DS39940, the USB module includes internal pull-up resistors on D+, simplifying board design. The wide 2.0V-3.6V supply range suits bus-powered designs drawing directly from the USB VBUS rail through a 3.3V LDO.

USB Host Mass Storage Reader
As an embedded USB host, the PIC24FJ128GB110T-I/PT enables products like USB flash drive readers, portable data loggers, and industrial backup devices. The full-speed (12 Mbps) host controller with OTG support handles USB Mass Storage Class (MSC) bulk-only transports without external PHY or host silicon. The 128KB Flash fits Microchip's MLA USB Host + FAT file system libraries with about 60KB remaining for application code, while 16KB RAM supports sector buffers and SCSI command structures. Hardware multiplier accelerates FAT directory traversal, and the 5x 16-bit timers provide timing for USB frame management. Per Microchip datasheet, the OTG module implements SRP and HNP protocols enabling role-swap designs. A companion companion chip such as MCP2200 USB-UART is unnecessary - this MCU integrates the host controller natively.

Capacitive Touch HMI Panel
The PIC24FJ128GB110T-I/PT is well-suited for capacitive touch human-machine interface (HMI) panels through the integrated Charge Time Measurement Unit (CTMU) module. The CTMU enables mTouch capacitive buttons, sliders, and proximity sensing with up to 32 channels available through I/O multiplexing. The 16 MIPS core runs Microchip's mTouch library plus debouncing and gesture recognition with sub-5ms response times. With 84 I/O, a 4.3-inch LCD can be driven through the PMP/EPMP module while capacitive touch buttons are scanned concurrently. The 16-channel 10-bit ADC at 500 ksps supports rotary encoders, temperature sensors, and analog front-ends. Per datasheet DS39940, the nanoWatt sleep modes drop quiescent current below 1 µA, ideal for battery-powered HMI remote controls where wake-on-touch returns the device to active mode.

Portable Data Logger with RTC
For portable data logging applications, the PIC24FJ128GB110T-I/PT integrates a 32-bit Real-Time Clock Calendar (RTCC) module with external 32.768 kHz crystal support, providing timestamped sensor records without external RTC chips. The 128KB Flash stores approximately 32,000 log records at 4 bytes each, while 16KB RAM provides a circular buffer for incoming sensor data. With nanoWatt power management and a sleep current under 1 µA per Microchip datasheet, the MCU runs for months on a 3V coin cell. The 16-channel 10-bit ADC at 500 ksps handles temperature, pressure, and humidity sensors through I2C/SPI interfaces or direct analog inputs. USB OTG enables the logger to dump data as a USB MSD device without driver installation, since most modern operating systems mount FAT volumes automatically.

Industrial Control with USB Diagnostic Port
In industrial control applications, the PIC24FJ128GB110T-I/PT serves as a control MCU plus USB diagnostic interface in one package. The 84 I/O drive relays, optocouplers, and digital sensors across multiple ports, while the USB OTG port provides field engineers with diagnostics, firmware updates, and parameter configuration without opening the cabinet. The wide 2.0V-3.6V supply tolerance accommodates 24V industrial rails stepped down to 3.3V by switching regulators, with the integrated BOR handling transient dips. Hardware CRC and DMA channels offload communication tasks from the 16 MIPS core. Per Microchip datasheet, the UART, SPI, and I2C peripherals coexist with USB for bridging industrial protocols (Modbus RTU, SPI sensors) to USB-CDC virtual COM ports on PC maintenance tools.

Medical Monitoring Wearable
The PIC24FJ128GB110T-I/PT fits medical monitoring wearables including heart-rate belts, pulse oximeters, and patient telemetry patches. The nanoWatt sleep modes (under 1 µA per Microchip datasheet) extend battery life beyond 30 days on a 250 mAh Li-ion cell, while the 16 MIPS core wakes for sub-second sensor acquisition windows. The CTMU module supports skin-contact touch sensors and proximity detection for wear detection, automatically powering down when removed. The 16-channel ADC digitizes ECG, SpO2, and temperature analog front-ends, while I2C drives accelerometer and gyro chips. USB OTG enables clinician-side charging cradles to read recorded data without specialized software - the device presents as a USB MSD with CSV-formatted health records. The -40C to +85C industrial temperature range spans clinical and home environments.

Заметки по проектированию
Decouple each VDD/AVDD pair with a 100 nF ceramic capacitor placed within 3 mm of the MCU pin, plus a 4.7 µF bulk capacitor on the main 3.3V rail. Per Microchip datasheet DS39940 section 2.4, the analog and digital supply pins are separated; bridging them with a ferrite bead reduces ADC noise injection by approximately 10 dB. For USB bus-powered designs, the VBUS pin can be used to sense attachment through an internal comparator.
Route USB D+ and D- as a 90 ohm differential pair on the top layer with continuous ground plane reference; length-match within 2 mm per USB 2.0 specification. Per Microchip USB hardware design guide, do not place any other traces or vias within 5 mm of the differential pair to preserve 90 ohm impedance. The 32.768 kHz crystal for the RTCC must be within 1 cm of SOSCO/SOSCI pins with trace capacitance below 10 pF.
At 32 MHz active current of approximately 10 mA at 3.3V, the 100-pin TQFP dissipates roughly 33 mW - well within the 1 W package rating with no heatsink required. Estimated: with theta_JA of approximately 50 C/W for the 12x12 mm TQFP, the junction temperature rise above ambient is 1.6C at full active load. Sleep currents below 1 µA per Microchip datasheet mean thermal concerns are negligible even in sealed enclosures.
Configure the JTAGEN configuration bit to disable if not using in-circuit debugging, otherwise pins RB10-RB13 are unavailable for GPIO. The ALTI2C configuration bit must be set correctly when remapping I2C1 to alternate pins to avoid bus contention. When using USB, the VUSB pin requires a 220 nF decoupling capacitor and must be enabled via the CONFIG3L register before the USB module powers up cleanly.
