This design consists of the RC56D parallel host interface device set and the R8292 USB Controller Unit (UCU). The R8292 operates with a 12 MHz crystal. A 32K x 8, 150 ns EEPROM is required for USB controller firmware. Additionally, one latch, one transistor, and two bus transceivers are required. The R8292 USB Controller is based on the MCS 51 microcontroller. It is a hubless USB pe
