Frequently Asked Questions
What is the USB transfer speed of the PIC18F25J50, and does it need an external PHY?
The PIC18F25J50 implements USB 2.0 full-speed at 12 Mbps using an integrated on-chip USB transceiver, eliminating the need for an external USB PHY chip. This integration reduces component count and simplifies PCB routing for USB-connected applications including HID controllers and virtual COM port adapters.
How much Flash memory does the PIC18F25J50 have, and is it enough for a USB firmware stack?
The PIC18F25J50 provides 32KB of Flash program memory, which accommodates Microchip's USB Framework library occupying approximately 8KB to 12KB alongside 15KB to 20KB of application firmware. For more complex USB composite device firmware, the PIC18F26J50 doubles Flash to 64KB while sharing the same 28-pin SOIC footprint.
At what supply voltage can the PIC18F25J50 operate in low-power mode?
The PIC18F25J50 operates at 8 MHz from a 2.15V minimum supply, enabling battery-powered operation from 2xAA or a single Li-ion cell. nanoWatt XLP sleep current falls below 100 nA, allowing coin-cell-powered wake-on-USB designs where the device wakes only when connected to a USB host.
For a USB data acquisition system, how many ADC channels does the PIC18F25J50 support?
The PIC18F25J50 includes a 10-bit ADC with up to 12 analog input channels accessible on the 28-pin SOIC package, providing 1,024 levels of resolution per channel. These channels can sample temperature sensors, voltage dividers, and strain gauges with data transmitted over USB CDC at up to 12 Mbps for real-time PC-based logging.
Is the PIC18F25J50 in SOIC-28 a good choice for hand-assembled prototypes?
The SOIC-28 package has 1.27 mm pin pitch and a 17.9 mm body, making it straightforward to solder by hand with a standard soldering iron. Low-cost DIP-28 to SOIC-28 adapter boards allow breadboard mounting, and the package is compatible with standard SMD stencil and reflow processes for production assembly.
