CY7C1350G Pin Definitions (continued) Name I/O Description ZZ Input- ZZ “sleep” Input. This active HIGH input places the device in a non-time critical “sleep” condition Asynchronous with data integrity preserved.During normal operation, this pin has to be low or left floating. ZZ pin has an internal pull-down. DQs I/O- Bidirectional Data I/O Lines. As inputs, they feed into an on-chip data register that is triggered Synchronous by the rising edge of CLK. As outputs, they deliver the data c
