Applications
PIC18F45K50-I/P is popular for USB peripheral development including HID keyboards, CDC virtual COM ports, and custom USB data acquisition devices that require 12 Mbps Full-Speed throughput without an external USB bridge chip. Its 12-bit ADC with 13 channels and on-chip DAC make it well suited for laboratory instruments, industrial panel controllers, and educational robotics platforms using 40-pin DIP breadboard prototyping. The 2.3 V minimum supply and power-managed sleep modes extend battery life in portable sensor loggers and field data recorders.

Frequently Asked Questions
Does PIC18F45K50-I/P include a USB controller, and what USB speed does it support?
Yes, PIC18F45K50-I/P integrates a USB 2.0 Full-Speed module operating at 12 Mbps, supporting HID, CDC, and custom device classes without any external USB-to-UART bridge chip, which saves at least one IC and simplifies driver development on Windows, macOS, and Linux hosts.
How many ADC channels does PIC18F45K50-I/P provide and what is the resolution?
The device includes a 12-bit ADC with up to 13 analog input channels, offering 4096 quantization levels for accurate measurement of sensor signals in the 0 V to 3.3 V or 0 V to 5 V reference range, suitable for temperature, pressure, and current sensing in embedded instruments.
What is the minimum supply voltage for PIC18F45K50-I/P and how does it benefit battery-powered designs?
PIC18F45K50-I/P operates from a minimum of 2.3 V at 20 MHz, allowing direct operation from two AA alkaline cells (nominally 3 V) or a single LiPo cell (3.0 V to 4.2 V), extending discharge runtime in portable data loggers by avoiding the power loss of a boost regulator.
What package does PIC18F45K50-I/P use, and why does it simplify prototyping compared to surface-mount variants?
PIC18F45K50-I/P uses a 40-pin PDIP package with 2.54 mm lead pitch, which fits directly into standard solderless breadboards and through-hole prototyping PCBs, allowing developers to test firmware with 35 GPIO lines, ICSP debug, and USB connectivity without SMT soldering skills or equipment.
When should a designer choose PIC18F45K50-I/P over PIC18F4550 for a USB HID project?
PIC18F45K50-I/P is preferred over PIC18F4550 when the design runs from a 3.3 V rail, since the K50 variant supports 2.3 V operation at 20 MHz versus 4.2 V minimum for PIC18F4550, and the K50 also adds a 12-bit ADC compared to the 10-bit ADC in PIC18F4550, providing higher analog measurement accuracy at 48 MHz.
