Key Features
- USB 2.0 Full-Speed device and OTG capability integrated on-chip eliminates external USB bridge ICs in embedded USB designs
- 256 KB Flash program memory with 16 MHz operation at 2 V minimum supply enables low-power USB peripheral applications from compact battery packs
- 80-pin TQFP package with JTAG boundary scan support simplifies board-level debug and production testing of complex multi-peripheral designs
Applications
The PIC24FJ256GB108-I/PT is ideal for USB-connected embedded systems such as HID devices, CDC virtual COM ports, mass storage applications, and USB data loggers where integrated Full-Speed USB 2.0 eliminates external USB bridge chips. Its 256 KB Flash and 32 MHz clock accommodate moderately complex firmware with USB stacks, display drivers, and multi-protocol serial communication in industrial handheld equipment and medical devices. The 2 V minimum supply voltage enables operation from two NiMH cells or regulated Li-ion converters in portable USB-enabled field instruments.

Frequently Asked Questions
What USB standard does PIC24FJ256GB108-I/PT support and does it require an external USB transceiver?
The PIC24FJ256GB108-I/PT integrates a Full-Speed USB 2.0 device and OTG controller operating at 12 Mbps, with an on-chip USB transceiver that requires no external USB PHY chip. This reduces BOM cost and board space compared to designs using a separate USB bridge IC, while supporting standard device classes including HID, CDC, and MSD directly from the 16-bit PIC24FJ core.
At what minimum supply voltage does PIC24FJ256GB108-I/PT operate and what clock speed is achievable?
The PIC24FJ256GB108-I/PT operates at a minimum supply voltage of 2 V while maintaining 16 MHz clock frequency. At higher supply voltages from 2.7 V to 3.6 V, the device scales up to 32 MHz. This low-voltage operation makes it suitable for two-cell alkaline or NiMH battery designs where the supply rail may drop below 2.5 V during discharge.
How much program memory does PIC24FJ256GB108-I/PT provide and is it adequate for a USB CDC firmware with an RTOS?
The PIC24FJ256GB108-I/PT includes 256 KB of Flash program memory and 16 KB of RAM. A USB CDC (virtual COM port) driver typically occupies 12–20 KB of Flash, leaving ample room for an RTOS kernel such as FreeRTOS (8–16 KB) and 200+ KB for application code, sensor drivers, and data buffers when running at up to 32 MHz on this 16-bit architecture.
Does the 80-pin TQFP package of PIC24FJ256GB108-I/PT support boundary scan for production testing?
Yes, the PIC24FJ256GB108-I/PT in the 80-pin TQFP package includes IEEE 1149.1 JTAG boundary scan capability. This enables automated board-level interconnect testing on production lines without manual probing, verifying solder joint integrity of all 80 pins and peripheral connections. JTAG also supports in-circuit programming and debug with MPLAB ICD or PICkit development tools.
