2.4 Circuit Description
A schematic of the USB08 demo board is provided in Appendix D. Bill
of Materials and Schematic . The MC68HC908JB8 MCU needs few
external elements. A wide range of peripheral functions including the
USB module and an 8-Kbyte FLASH memory are integrated on-chip.
The MC68HC908JB8 is offered in several packages. For the USB08
reference design, the 28-pin SOIC version was chosen instead of the
20-pin dual in-line package (DIP) because the SOIC package has some
additional I/O pins.
