Key Features
- Integrated USB 2.0 full-speed controller eliminates the need for an external USB bridge chip, reducing BOM cost
- 32 KB Flash program memory and 2 KB RAM support complex firmware stacks including USB HID and CDC class drivers
- 12-bit ADC with multiple channels enables precision analog sensing alongside digital USB communication
- Wide supply voltage range down to 2 V minimum at 4 MHz for low-power battery-operated USB devices
- 48 MHz maximum clock frequency from internal PLL allows full USB timing compliance without external crystal in many configurations
Applications
The PIC18LF2553-I/SO is ideal for USB-connected embedded peripherals such as HID devices, virtual COM port adapters, and data loggers that bridge analog sensors to a PC via USB 2.0. Its 32 KB Flash and 12-bit ADC make it suitable for custom instrumentation front-ends, USB audio accessories, and programmable keyboard or input device firmware. Battery-operated USB devices benefit from the 2 V minimum operating voltage, which extends runtime from two-cell alkaline or Li-ion supplies.

Frequently Asked Questions
Does the PIC18LF2553-I/SO include native USB support, and what USB speed does it support?
Yes, the PIC18LF2553-I/SO integrates a full-speed USB 2.0 controller operating at 12 Mbps, eliminating the need for an external USB bridge IC. This allows direct PC connectivity for HID, CDC virtual COM port, and mass-storage class firmware implementations using Microchip's USB stack on just 32 KB Flash.
How much program and data memory does the PIC18LF2553-I/SO provide for firmware development?
The PIC18LF2553-I/SO provides 32 KB of on-chip Flash program memory and 2 KB of SRAM data memory. This capacity comfortably accommodates a USB class driver alongside application code, with room for a bootloader in the lower Flash pages to enable field firmware updates over the USB connection without an external programmer.
What is the minimum supply voltage for the PIC18LF2553-I/SO, and how does it affect clock speed?
The PIC18LF2553-I/SO operates from a minimum supply of 2 V, but at this voltage the maximum clock frequency is limited to 4 MHz. At the nominal 3.3 V or 5 V supply, the device clocks up to 48 MHz using the internal PLL, enabling full USB 2.0 full-speed timing compliance and maximum peripheral throughput.
Which package does the PIC18LF2553-I/SO use, and how many I/O pins does it expose?
The PIC18LF2553-I/SO is housed in a 28-pin SOIC package with 1.27 mm pin pitch. It exposes up to 25 general-purpose I/O pins, supporting digital I/O, analog inputs for the 12-bit ADC, SPI, I2C, two UART interfaces, and USB D+/D- lines—all accessible on a standard SMD footprint suitable for compact 4-layer PCBs.
