PICDEM™ FS USB Demonstration Board

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 is dual port)

• 256 bytes of data EEPROM

• Full-Speed USB 2.0 interface (capable of 12 Mbit/s

data transfers) including FS-USB transceiver and

voltage regulator

Features

The demonstration board provides the following

functions:

• Temperature sensor TC77 (connected to the

C™ bus)

• Potentiometer (connected to RA0 input) for

A/D conversion demonstrations

• 2 LEDs for status display

• 2 input switches

• Reset button

• 20 MHz crystal

• Serial port connector/interface (for demonstrations 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 Board standard

The board comes preloaded with a USB bootloader that

demonstrates the Enhanced Flash memory capabilities

of the device in addition to allowing the user to

reprogram the PIC18F4550 in-circuit without requiring

use of an external programmer. A CD-ROM is also

included in the kit, offering access to a wealth of

documentation and information about the board, as well

as application notes and software libraries for immediate

support of the HID, CDC and Custom classes.
