Summary

The PICDEM FS-USB is a demonstration and evaluation board for the PIC18F4550 family of Flash microcontrollers with full speed USB 2.0 interface. The board contains a PIC18F4550 microcontroller in a 44-pin TQFP package, representing the superset of the entire family of devices offering the following features:

48 MHz maximum operating speed (12 MIPS)
32 Kbytes of Enhanced Flash memory
2 Kbytes of RAM (of which 1 Kbyte dual port)
256 bytes of data EEPROM
Full Speed USB 2.0 interface (capable of 12 Mbit/s data tranfers), including FS-USB transceiver and voltage regulator
The demonstration board provides the following functions:

20 MHz crystal
serial port connector/interface (for demonstration of migration from legacy applications)
connection to the MPLAB ICD 2 In Circuit Debugger
voltage regulation, with the ability to switch from external power supply to USB bus supply
expansion connector, compatible with the PICtail daughter boards standard
temperature sensor TC77 (connected to the SPI bus)
potentiometer (connected to RA0 input) for A/D conversion demonstrations
2 LEDs for status display
