USB DPLUS Signal Connect to the USB DPLUS signal.
USB DMINUS Signal Connect to the USB DMINUS signal.
Bidirectional Data Bus This bidirectional bus is used as the entire data
bus in the 8-bit bidirectional mode or the least significant eight bits in the
16-bit mode. Under the 8-bit unidirectional mode, these bits are used as
inputs for data, selected by the RxValid signal.
Bidirectional Data Bus This bidirectional bus is used as the upper eight
bits of the data bus when in the 16-bit mode, and not used when in the
8-bit bidirectional mode. Under the 8-bit unidirectional mode these bits
are used as outputs for data, selected by the TxValid signal.
Clock This output is used for clocking the receive and transmit parallel
data on the D[15:0] bus.
Active HIGH Reset Resets the entire chip. This pin can be tied to V
through a 0.1-μF capacitor and to GND through a 100 K resistor for a
10-ms RC time constant.
Transceiver Select This signal selects between the Full Speed (FS) and
the High Speed (HS) transceivers:
0: HS transceiver enabled
1: FS transceiver enabled
Termination Select This signal selects between the Full Speed (FS) and
the High Speed (HS) terminations:
0: HS termination
1: FS termination
Suspend Places the CY7C68000A in a mode that draws minimal power
from supplies. Shuts down all blocks not necessary for Suspend/Resume
operations. While suspended, TermSelect must always be in FS mode
to ensure that the 1.5 Kohm pull up on DPLUS remains powered.
0: CY7C68000A circuitry drawing suspend current
1: CY7C68000A circuitry drawing normal current
