Frequently Asked Questions
Does PIC24FJ256GB406-I/PT include USB and what speed does it support?
Yes. The PIC24FJ256GB406-I/PT includes a full-speed USB module supporting USB 2.0 at 12 Mbit/s in both device and OTG configurations. This allows the MCU to enumerate as a CDC, HID, or mass storage device without an external USB controller, reducing system cost and component count.
How does the built-in DMA on PIC24FJ256GB406-I/PT benefit ADC or audio streaming applications?
The DMA channels on PIC24FJ256GB406-I/PT allow ADC conversion results or DAC output data to be transferred to or from SRAM automatically, without stalling the 32 MHz CPU. This is essential in audio streaming, high-speed data logging, and communication buffering tasks where interrupt-driven transfers would otherwise saturate the core.
Which package does PIC24FJ256GB406-I/PT use, and how many I/O pins are available?
The PIC24FJ256GB406-I/PT comes in a TQFP-64 package, offering up to 64 pins including GPIO, analog inputs, and peripheral signal pins. The quad flat package with 0.5 mm pitch is compatible with standard SMT pick-and-place assembly and provides adequate I/O density for industrial control and HMI designs.
What is the procurement lead time for PIC24FJ256GB406-I/PT and how stable is its supply?
Microchip lists PIC24FJ256GB406-I/PT with a factory lead time of 7 weeks and a YTEOL of 13 years, reflecting an active production part with a long remaining lifecycle. Buyers sourcing for volume production should place orders through authorized distributors and confirm stock levels against their program build schedule.
