Key Features
- Integrated USB 2.0 full-speed engine at 48 MHz eliminates the need for an external USB bridge chip in compact HID, CDC, and custom class device designs
- Low-voltage operation down to 1.8V at 20 MHz extends battery life in USB-powered and energy-harvesting portable applications
- 10-bit ADC with multiple input channels enables direct acquisition of analog sensor signals without external components
- SSOP-20 package delivers a small footprint with 20 configurable I/O pins, suitable for size-constrained USB peripheral boards
Applications
The PIC18LF14K50-I/SS targets low-pin-count USB peripheral designs including HID keyboards and mice, CDC virtual COM-port adapters, USB-to-sensor bridges, and custom USB data-logging dongles. Its 1.8V minimum operating voltage and integrated USB 2.0 engine make it a cost-effective single-chip solution for battery-powered USB accessories and IoT gateway modules that must enumerate directly on a USB host without an external USB controller.

Frequently Asked Questions
Does the PIC18LF14K50-I/SS have an integrated USB controller, and which USB classes does it support?
Yes. The PIC18LF14K50-I/SS includes a built-in USB 2.0 full-speed (12 Mbps) engine with 8 bidirectional endpoints, natively supporting HID, CDC, mass-storage, and custom USB device classes using Microchip's free USB stack firmware, removing the need for an external USB transceiver chip.
What is the minimum supply voltage for the PIC18LF14K50-I/SS, and how does it affect clock speed?
The device operates from a minimum of 1.8V supply, at which speed is limited to 20 MHz. At 3.3V or 5V it can reach up to 48 MHz, and the USB peripheral requires a stable 3.3V or an internal 3.3V regulator enabled from a 5V bus to meet USB electrical specifications.
How many I/O pins does the PIC18LF14K50-I/SS expose, and which communication interfaces are available?
The 20-pin SSOP package exposes up to 18 general-purpose I/O pins with UART, SPI, and I2C peripherals, along with a 10-bit ADC supporting 13 input channels, enabling multi-protocol sensor interfacing in a small 20-pin footprint suitable for USB dongle or embedded module designs.
How does the PIC18LF14K50-I/SS compare to the non-LF PIC18F14K50 variant in terms of voltage tolerance?
The LF suffix indicates the low-voltage variant, specifying a 1.8V to 5.5V operating range versus 2.3V to 5.5V for the standard PIC18F14K50. This broader range allows the LF device to interface directly with 1.8V logic rails in modern SoC-based systems without additional level-shifting components.
