Frequently Asked Questions
How does the PIC18F45J50-I/PT support USB 2.0 full-speed communication without an external bridge?
The PIC18F45J50-I/PT integrates a full-speed USB 2.0 engine operating at 48 MHz, eliminating the need for external USB-to-serial bridge ICs like CP2102 or FT232, which reduces BOM cost and PCB area on USB HID, CDC, and custom class device designs.
What low-power operating mode does the PIC18F45J50-I/PT offer when USB is suspended?
The PIC18F45J50-I/PT can operate at 8 MHz from a reduced 2.15 V supply when USB is suspended or inactive, cutting dynamic current consumption substantially compared to full-speed 48 MHz operation, which extends battery life in portable USB accessories and wearable sensor devices.
Which USB device classes can the PIC18F45J50-I/PT implement using Microchip's USB stack?
Using Microchip's USB stack, the PIC18F45J50-I/PT can implement HID, CDC/ACM virtual COM, Mass Storage, and custom vendor-specific USB classes within its 32 KB Flash, allowing designs ranging from keyboard emulators to USB data-logging accessories that enumerate natively on Windows, macOS, and Linux at 12 Mbps.
