PIC24FJ256GB210T-I/PT Overview
A PIC24F microcontroller is a 16-bit Harvard-architecture MCU that sits in Microchip's mid-range portfolio, positioned above the 8-bit PIC16/PIC18 families and below the 32-bit PIC32MX parts. PIC24F parts use a modified RISC instruction set with 24-bit instructions, 16-bit data paths, and hardware multiply/divide, giving a typical 1.5 to 2x performance uplift over PIC18 while preserving the MPLAB X toolchain and XC16 compiler ecosystem. They fall within the broader taxonomy: PIC24 -> PIC24F -> 16-bit MCU -> microcontroller -> embedded IC -> semiconductor. This GB210 variant adds an integrated USB 2.0 full-speed OTG transceiver and the Peripheral Pin Select (PPS) feature that allows remapping of digital peripherals to any GPIO.
Key features include 256 KB (85.5K x 24) self-programmable Flash, 96 KB RAM, hardware Real-Time Clock and Calendar (RTCC), a 16-channel 10-bit ADC, 5 PWM modules, and multiple UART/SPI/I2C modules. Integrated peripherals also include DMA, a parallel master port, and a charge time measurement unit (CTMU). The chip supports 5V-tolerant I/O when the supply is 3.3V, simplifying mixed-voltage interfacing in industrial designs.
The architecture combines a 16-bit ALU with a 24-bit instruction word for code-efficient C compilation, while on-chip peripherals reduce external component count. The USB OTG controller handles full-speed (12 Mbps) device, host, and OTG roles without an external PHY, and PPS allows flexible pin assignment to reduce PCB routing congestion in dense 100-TQFP designs.
Typical applications include USB peripherals (HID, CDC, MSD), USB medical and industrial instrumentation, embedded host devices reading USB flash or HID peripherals, OTG dual-role designs such as data loggers and portable instruments, and human-machine interface (HMI) panels with graphics or touch. Designers should evaluate the Explorer 16/32 development board with the matching Plug-In Module (PIM) to accelerate prototyping and reuse code between PIC24F and dsPIC33 families via pin-compatible footprints.
When designing with this device, leverage the PPS feature to route peripherals after layout, allocate at least one DMA channel for USB endpoints to offload the CPU, and ensure VUSB and VBUS sensing pins are properly decoupled with the values listed in the manufacturer datasheet.

Typical Applications
PIC24FJ256GB210T-I/PT is suitable for 6 applications: USB HID / CDC / MSD Peripherals, Embedded USB Host (USB Flash / HID Reader), Industrial Data Acquisition with USB Streaming, Portable Medical / Health Devices, Human-Machine Interface (HMI) Panels with USB Diagnostics, Consumer Audio / HID Dongles.
USB HID / CDC / MSD Peripherals
The PIC24FJ256GB210T-I/PT is ideal for USB peripherals because it integrates a full-speed USB 2.0 OTG transceiver (12 Mbps) without an external PHY, freeing board space and BOM cost. With 256 KB Flash and 96 KB RAM, the part can host the Microchip USB stack plus HID, CDC, and MSD class drivers concurrently for composite devices such as data loggers or instrumentation bridges. Place the part near the USB connector with the D+/D- traces matched to 90 ohm differential impedance and 15 kohm pull-downs on D+/D- per USB spec. At 32 MHz / 16 MIPS the CPU sustains USB polling and bulk transfers without offloading to DMA.
Recommended
Embedded USB Host (USB Flash / HID Reader)
The GB210's integrated USB OTG supports embedded-host mode, allowing the MCU to read USB flash drives, USB keyboards, or barcode scanners without a PC. Its 256 KB Flash accommodates the Microchip USB host stack and FAT file-system library, while 96 KB RAM buffers USB sectors and file-system caches in real time. Use the 32 kHz secondary oscillator plus RTCC for time-stamping captured data, and route the VBUS pin through an N-channel MOSFET to switch 5V to the USB-A receptacle. Compared to an external USB host IC, this single-chip solution reduces PCB area and total BOM while keeping power under 100 mA per-port in default configuration.
Recommended
Industrial Data Acquisition with USB Streaming
Engineers building USB streaming data acquisition modules (DAQ, oscilloscope probes, sensor gateways) can leverage the GB210's 16-channel 10-bit ADC, 8 DMA channels, and 32 MHz throughput to sample and stream analog data over USB CDC or vendor-class bulk endpoints. The 5V-tolerant digital I/O simplifies interfacing to legacy 5V industrial sensors while running from a 3.3V rail. Pair the part with external op-amps for gain and add the CTMU peripheral for temperature-compensated capacitance measurement. The XLP deep-sleep mode reduces idle current to a few hundred nA for battery-powered field loggers that wake to push data over USB.
Recommended
Portable Medical / Health Devices
Battery-powered medical peripherals (blood-pressure monitors, glucose meters, USB-charged thermometers) benefit from the GB210's XLP low-power architecture, integrated USB for charging and data sync, and 84 I/O for sensor front-ends and displays. The CTMU peripheral enables accurate temperature measurement for clinical thermometers, while the 16-bit timers drive precise PWM for haptic feedback or buzzer control. Operating from 2.0-3.6V accommodates a single Li-ion cell, and the -40°C to +85°C industrial temperature range supports most healthcare environments.
Recommended
Human-Machine Interface (HMI) Panels with USB Diagnostics
For HMI panels that need a USB diagnostics port (firmware update, log export), the GB210 supplies 256 KB Flash for graphics libraries and 84 I/O for keypad, LEDs, and segment-LCD drivers via the Parallel Master Port (PMP). Although the DA210 variant adds an integrated graphics controller, the GB210 still drives small TFTs via PMP with sufficient throughput for status screens and menus, while reserving USB for service logs. PPS simplifies routing the SPI display and USB on adjacent PCB layers.
Recommended
Consumer Audio / HID Dongles
USB audio dongles, presenter remotes, and HID combo devices leverage the GB210's USB OTG plus the PIC24F's fast interrupt response (<200 ns) to handle real-time HID reports at 1000 Hz polling. The 96 KB RAM buffers audio descriptors and HID report tables without external memory, while the 256 KB Flash accommodates composite USB stacks and vendor-specific commands. The small 100-TQFP footprint and Tape & Reel packaging suit high-volume consumer manufacturing lines.

Key Differentiators
- Integrated USB 2.0 FS OTG without external PHY (vs PIC24FJ256GA610-I/BG)
- Highest-density USB MCU in the PIC24F GB2xx family (vs PIC24FJ128GB110-I/PT)
- AEC-Q100 automotive-qualified option available (vs PIC24FJ256GB210-I/PT (Industrial))
- eXtreme Low Power (XLP) technology on-chip (vs PIC24FJ192GB110-I/PT)
Design Notes
Route the USB D+ and D- traces as a 90-ohm differential pair, length-matched within 150 mil, and keep them short (under 50 mm total) directly from the MCU to the USB connector. Place the VBUS decoupling capacitor (4.7 uF recommended per the Microchip PIC24FJ256GB210 family datasheet) within 5 mm of the VBUS pin. Maintain an unbroken ground plane beneath the USB traces for controlled impedance.
The MCU operates from a single 2.0 V to 3.6 V supply; place a 10 uF bulk + 0.1 uF decoupling capacitor pair on each VDD/VSS pin pair and as close as possible to the package. VUSB requires its own 0.1 uF decoupling capacitor placed within 3 mm of pin 6. In battery-powered designs, switch the MCU between the 8 MHz internal FRC and the 32 kHz secondary oscillator to draw down to a few hundred nA in deep sleep.
Estimated: the 'T' suffix only changes the shipping medium (Tape & Reel vs Tray) - it does NOT indicate a different temperature grade; the 'I' suffix denotes the industrial -40C to +85C range. Confusing 'T' with 'temperature' can lead to specifying the wrong part for outdoor or AEC-Q100 applications. For automotive designs use the -QTP/-QFP variants. Always verify the marking on the reel versus the data sheet before placing.
Use the Peripheral Pin Select (PPS) feature to map UART/SPI/I2C peripherals to the most routing-friendly GPIO pins post-layout. PPS requires explicit unlock sequence in firmware - forgetting it is a common source of 'silent peripheral' bugs. For USB OTG, ensure the 15 kohm pull-down resistors on D+ and D- are present per USB 2.0 spec when operating in host mode; otherwise attach detection will fail.
Compliance Information
RoHS compliant per Microchip product page. Standard 'I' temperature variant is industrial grade (AEC-Q100 not applicable); for automotive designs, choose the -QTP/-QFP variants which are AEC-Q100 qualified.
