Frequently Asked Questions
How fast can the PIC18F25J50-I/SS run, and what voltage does it need at that speed?
The PIC18F25J50 reaches a maximum clock frequency of 48 MHz. At full speed it requires a supply voltage in the standard operating range; however, it can also operate at 8 MHz when supplied as low as 2.15 V, enabling low-power or battery-backed designs without a regulated 3.3 V rail.
Which USB class implementations does the PIC18F25J50 support natively?
The device includes a built-in USB 2.0 full-speed controller running at 12 Mbps, making it directly usable for HID, CDC, and vendor-class device firmware. With 32 KB of Flash and 3.8 KB of RAM on board, a small USB stack and application code fit without external memory.
Is the SSOP-28 footprint compatible with standard PCB assembly for the PIC18F25J50?
Yes. The 28-pin SSOP package uses a 0.65 mm pitch, which is handled by most automated SMT pick-and-place and reflow lines. The footprint is compact enough for space-constrained boards while still providing all 28 GPIO and peripheral pins, including the ADC inputs and the USB D+/D- lines.
What serial interfaces are available on the PIC18F25J50-I/SS for sensor integration?
The PIC18F25J50 provides hardware UART, SPI master/slave, and I2C master/slave peripherals. These 3 interfaces cover the most common sensor buses, and the on-chip ADC adds direct analog input capability, reducing external component count in data-acquisition and industrial sensing applications.
When would a designer choose the PIC18F25J50 over a larger PIC18 device with more Flash?
For applications where firmware stays under 32 KB and USB connectivity is required, the PIC18F25J50 avoids paying for unused Flash on larger variants. Its 48 MHz maximum speed and 3.8 KB RAM are sufficient for CDC or HID USB stacks, keeping BOM cost low in moderate-volume consumer or industrial products.
