Key Features
- Full-speed USB 2.0 device interface integrated on-chip, eliminating the need for an external USB bridge in 28-pin SOIC package
- 32 KB Flash program memory with 4 KB RAM and nanoWatt XLP technology for ultra-low standby and sleep current consumption
- Operates at up to 48 MHz from 3.3 V supply or 8 MHz at 2 V, enabling battery-optimized designs without external voltage regulators
Applications
PIC18LF25J50-I/SO is ideal for USB-connected embedded systems such as HID keyboard and mouse devices, CDC serial-over-USB adapters, and USB data loggers where direct USB connectivity and low power are required in a compact 28-pin SOIC footprint. The nanoWatt XLP technology enables battery-operated USB devices to maintain very low sleep current, extending runtime in portable instrumentation and remote sensing nodes. Its 32 KB Flash and 4 KB RAM capacity suits moderate-complexity USB firmware with interrupt-driven peripherals including ADC-based sensor acquisition.

Frequently Asked Questions
What is the maximum clock frequency of the PIC18LF25J50-I/SO, and can it run at lower voltages?
The PIC18LF25J50-I/SO runs at up to 48 MHz from a standard 3.3 V supply for full-speed USB operation. It also supports 8 MHz operation at 2 V supply, making it suitable for battery-powered designs where the supply may drop to near 2 V as cells discharge. This dual-voltage operation helps designers balance processing speed against battery longevity without changing microcontroller families.
How much Flash and RAM does the PIC18LF25J50-I/SO provide for firmware storage?
This MCU includes 32 KB of Flash program memory and 4 KB of RAM data memory. The 32 KB Flash capacity is sufficient for moderate-complexity USB firmware stacks such as Microchip's USB stack with HID or CDC class drivers, while 4 KB of RAM provides enough buffer space for USB endpoint descriptors, application data, and RTOS-style task stacks in interrupt-driven designs.
What type of USB does the PIC18LF25J50-I/SO support, and which USB device classes can it implement?
The PIC18LF25J50-I/SO incorporates a full-speed USB 2.0 device interface at 12 Mbps on-chip. It supports Microchip's USB firmware stack for implementing HID (keyboard, mouse, gamepad), CDC (virtual COM port), and custom vendor-class USB device profiles. The integrated USB transceiver eliminates the need for external bridge chips, reducing BOM cost and PCB space in 28-pin SOIC designs.
For battery-powered USB accessories, how does the PIC18LF25J50-I/SO's nanoWatt technology help extend runtime?
The nanoWatt XLP (eXtreme Low Power) technology in the PIC18LF25J50-I/SO reduces sleep current to the nanoampere range, allowing the MCU to enter deep sleep between USB transactions or during idle periods. Combined with the ability to run at 8 MHz from a 2 V supply, this MCU can dramatically extend battery life in USB HID devices and battery-backed data loggers compared to standard PIC18 cores without XLP features.
