3. Hardware Features
USB to MON08 Interface
This section contains the circuitry needed to electrically and logically translate MON08-like
commands sent by the host PC through the USB cable to the MON08 interface of the
microcontroller.
The USB interface is based on a Freescale MC68HC908JB16 microcontroller, which
features an on-board, low-speed USB peripheral.
The USB bus provides the power supply for the board. To protect the USB bus against short
circuits that may occur during experiments, the power supply circuitry features a 200 mA
3
auto-restore fuse.
Note: even though USB specifications require low-speed devices to be used only with a
captive or manufacturer-specific USB cable, we have decided to use a standard USB cable.
We therefore recommend that you use the PK-HC08QY4 board with the USB cable
provided or, if you use another USB cable, ensure that the cable length does not exceed 2
meters.
