Evaluation board microchip DM163025
The PICDEM FS-USB is a demonstration and evaluation board for the PIC18F4550 family of Flash microcontrollers with full speed USB 2.0 interface.
Detailed Description
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
- 2 input switches
- reset button
The board comes pre-loaded with a USB bootloader that demonstrates the Enhanced Flash memory capabilities of the device. The PIC18F4550 can be re-programmed in circuit without an external programmer.
A CD-ROM is also included in the kit which contains full documentation about the board, application notes and software libraries for support of the HID, CDC and custom classes.
