USB245

The USB245 is small, easy to use device with all necessary timing circuits, and power filtering built in. Each contains a preprogrammed EEPROM which holds the device and vendor ID codes.

The 8-bit data bus easily connects to processor data buses. The two control bus lines (READ# and WRITE) direct data flow from the device, while two status lines (TXE# and RXF#) give information about the state of the internal transmit and receive FIFOs. The status lines can also be used as interrupt sources for the processor.

The onboard RESET# line of the USB245 is routed externally and can be used to drive other circuits.

The USB245 can be wired to derive and source power from the USB bus, or alternatively have power sourced from the processor interface.
