Key Features
- 48 MHz 8-bit PIC18 core with 32KB Flash and integrated USB 2.0 full-speed peripheral, enabling direct USB connectivity without an external USB controller
- Ultra-low voltage operation from 1.8V minimum supply at 4 MHz supports coin-cell and single-cell Li-ion battery-powered USB device designs
- 13-channel 10-bit ADC plus integrated DAC provide a complete analog front end for sensor acquisition and analog output in compact 28-pin SSOP footprint
Applications
The PIC18LF25K50-I/SS is well suited for USB-connected embedded devices such as HID keyboards, USB data loggers, and USB-to-serial bridges where integrated USB 2.0 full-speed capability at 48 MHz eliminates the need for an external USB controller chip. Its 1.8V minimum supply makes it ideal for low-power portable applications powered by single-cell lithium batteries or energy harvesters with ADC-based sensor measurement. The 28-pin SSOP package offers a compact PCB footprint for consumer electronics, wearable devices, and industrial USB instrumentation requiring multi-channel analog input with DAC output.

Frequently Asked Questions
Does the PIC18LF25K50-I/SS have integrated USB support, and at what speed does it operate?
Yes, the PIC18LF25K50-I/SS integrates a USB 2.0 full-speed peripheral operating at 12 Mbps, allowing it to enumerate directly as a USB device without an external USB controller. Combined with its 48 MHz CPU clock and 32KB Flash, this makes it a cost-effective single-chip solution for HID devices, USB data loggers, and USB-to-UART bridges.
What is the minimum supply voltage of the PIC18LF25K50-I/SS and how does it benefit battery-powered designs?
The PIC18LF25K50-I/SS operates from a minimum supply of 1.8V at 4 MHz, which is within the discharge range of a single-cell Li-ion battery (discharges to about 2.7V) and above the 1.5V end-of-life voltage of an AA alkaline cell. This low-voltage capability extends operating time in portable USB devices and wearable sensors without a boost regulator.
How many ADC channels does the PIC18LF25K50-I/SS provide and what resolution do they offer for sensor applications?
The device includes 13 ADC input channels with 10-bit resolution, providing 1,024 discrete levels per measurement. This allows simultaneous monitoring of 13 analog sensors — such as temperature, pressure, or light sensors — within a single 28-pin SSOP device, eliminating the need for external ADC multiplexers in multi-sensor data acquisition designs.
When would the PIC18LF25K50-I/SS be preferred over a PIC18F25K50 for the same USB design?
The LF (low-voltage) variant PIC18LF25K50 is preferred when the system supply rail is between 1.8V and 3.6V, such as in single-cell LiPo or coin-cell battery applications. The standard PIC18F25K50 requires a minimum of 2.3V, so the LF version provides an additional 0.5V of operational headroom at the bottom of the supply range, extending battery runtime before the MCU drops out of regulation.
