PDIUSBD12
USB interface device with parallel bus
Philips Semiconductors
■ Double buffering scheme for main endpoint increases throughput and eases
real-time data transfer
■ Data transfer rates: 1 Mbytes/s achievable in Bulk mode, 1 Mbits/s achievable in
Isochronous mode
■ Bus-powered capability with very good EMI performance
■ Controllable LazyClock output during suspend
■ Software controllable connection to the USB bus (SoftConnect™)
■ Good USB connection indicator that blinks with traffic (GoodLink™)
■ Programmable clock frequency output
