PIC24FJ256GB106T-I/PT - 32MHz 256KB Flash USB OTG MCU | Microchip
MPN: PIC24FJ256GB106T-I/PT ✓ Hoạt độngPIC24FJ256GB106T-I/PT Tóm tắt
A 16-bit MCU (microcontroller unit) is a programmable embedded processor that integrates CPU core, memory, peripherals, and I/O on a single die. Within Microchip's product hierarchy, this part sits under the PIC24F family, which targets low-power (nanoWatt) general-purpose applications with rich connectivity. It belongs to the broader microcontroller category within the semiconductor landscape, sitting alongside 8-bit (PIC16/PIC18) and 32-bit (PIC32) siblings.
Key differentiating features include 256KB Flash (85.5K x 24 instruction words), 16KB RAM, hardware USB OTG with PHY, 52 I/O pins with Peripheral Pin Select (PPS), and an extensive peripheral set (3x I2C, 3x SPI, 4x UART, 23 timers). The device also integrates a Real-Time Clock and Calendar (RTCC), 16-channel 10/12-bit ADC, and nanoWatt power-saving modes with sub-100nA standby current.
The PIC24FJ256GB106 family uses the MIPS-modified Harvard architecture with a modified RISC instruction set, allowing C-friendly compiled code density. Integrated USB OTG eliminates the need for an external PHY, simplifying BOM and PCB area. PPS provides flexible remapping of digital peripherals to physical pins, easing PCB layout.
Typical applications include USB peripherals (HID, CDC, MSD), industrial control and HMI, low-power sensor nodes with USB charging, embedded data loggers with USB mass storage, and human interface devices such as touch key panels and remote controls.
When designing with this part, ensure VUSB capacitor placement follows the manufacturer's reference layout to meet USB signal-integrity compliance, and use the PPS feature to optimize pin assignments for mechanical connector placement.

Ứng dụng tiêu biểu
PIC24FJ256GB106T-I/PT phù hợp cho 6 Áp dụngs: USB Human Interface Device (HID), Industrial Control and HMI, USB Mass Storage Data Logger, Low-Power Sensor Node with USB Charging, USB OTG Dual-Role Device, Consumer Touch Interface.
USB Human Interface Device (HID)
The PIC24FJ256GB106T-I/PT's integrated USB OTG full-speed and high-speed controller with on-chip PHY makes it ideal for USB HID peripherals such as keyboards, mice, game controllers, and custom input devices. With 16 MIPS performance and 256KB Flash, designers can run full HID stacks plus application code, while the 16KB RAM comfortably buffers HID report packets without DMA. PPS flexibility simplifies PCB layout for mechanical enclosure constraints, and the 52 I/O pins support multi-button matrices and LED indicators. NanoWatt modes extend battery life in wireless HID dongles drawing <100nA standby current.

Industrial Control and HMI
The PIC24FJ256GB106T-I/PT suits industrial HMI panels with its 52 I/O pins, 16-channel ADC, and RTCC for time-stamped event logging. The 32MHz/16 MIPS core can scan keypads, drive LCDs, and process analog sensor inputs in real time. Peripheral Pin Select remaps digital functions to any I/O, easing PCB routing in tight enclosures. Industrial temperature rating (-40C to +85C) supports factory-floor deployment. Pair with the PIC24FJ256DA206-I/PT for designs requiring higher ADC resolution on the same family.

USB Mass Storage Data Logger
The PIC24FJ256GB106T-I/PT enables USB mass storage data loggers that record sensor data to USB flash drives or appear as MSD devices to a host PC. The 256KB Flash holds the MSD stack and FAT file system library; the 16KB RAM caches sector writes to amortize USB throughput. Hardware USB OTG with on-chip PHY removes the need for external transceivers, reducing BOM cost and PCB area. With 16 MIPS, designers can sample sensors at kHz rates while maintaining a real-time USB isochronous endpoint.

Low-Power Sensor Node with USB Charging
The PIC24FJ256GB106T-I/PT's nanoWatt power management with sub-100nA standby current suits battery-powered sensor nodes that periodically wake, sample, and recharge via USB. The 16-channel ADC reads analog sensors; RTCC schedules wake events; and USB OTG handles Li-ion charging from any USB host. With 23 timers, designers can implement PWM-driven sensor excitation, low-power sleep cycles, and interrupt-driven wakeups without external RTC chips. PPS allows the USB D+/D- lines to be routed away from analog traces for cleaner signal integrity.
Được đề xuất
USB OTG Dual-Role Device
The PIC24FJ256GB106T-I/PT supports USB On-The-Go dual-role operation, allowing embedded products to act as either USB device or USB host depending on the attached cable. This is critical for field-service tools, point-of-sale terminals, and embedded diagnostic instruments that connect to PCs as devices or attach USB peripherals as hosts. With 256KB Flash and 16KB RAM, designers implement OTG role-swap state machines plus full USB stacks. PPS enables optimized pin routing for the ID-pin detection and VBUS sensing circuits.
Được đề xuất
Consumer Touch Interface
The PIC24FJ256GB106T-I/PT supports capacitive touch sensing via the CTMU peripheral, enabling slider, button, and proximity touch interfaces for consumer appliances. With 52 I/O pins, designers can support 32+ touch channels plus LEDs and a USB firmware-update interface on the same MCU. The 32MHz performance handles real-time touch scanning while maintaining USB CDC command responses. Industrial temperature rating supports appliance environments, and the 64-TQFP package's 10x10mm footprint fits standard touch-panel PCB outlines.

Ghi chú thiết kế
USB D+ and D- traces must be routed as a 90-ohm differential pair with matched length (within 150 mil). Place the VUSB decoupling capacitor (4.7uF recommended) within 5mm of the VUSB pin to suppress USB inrush transients. The 64-TQFP package allows a clean break-out for USB signals on the right edge of the device (pins 33/34), simplifying PCB stack-up.
The PIC24FJ256GB106T-I/PT operates from 2.0V to 3.6V; a 3.3V LDO is typical. Estimated: at 32 MHz full activity and USB transmitting, peak current is approximately 35 mA. Place 100nF ceramic decoupling capacitors on every VDD pin pair (pins 12, 20) and a bulk 10uF tantalum or ceramic near the package. Add a ferrite bead on VBUS if the system bus-powered to avoid back-powering issues.
Peripheral Pin Select (PPS) remapping must be configured in software before using remapped peripherals; otherwise the I/O pin will not drive the peripheral function. Always unlock the PPS register sequence (IOLOCK bit) before configuration. Also note that nanoWatt Sleep mode disables the USB controller; designs needing USB wakeup must use Idle mode or interrupt-on-change from D+/D- instead.
The 23.5 KB/s USB full-speed signaling requires the on-chip PHY's internal pull-up on D+ to be enabled only after configuration is complete. Add an external 1.5 kohm pull-up on D+ for high-speed mode unless the internal pull-up is enabled per the datasheet. Keep analog signals away from the oscillator pins (39/40) to avoid coupling into the USB PLL.
