7 / 36 page  CY7C1386CV25 CY7C1387CV25 Document #: 38-05242 Rev. *A Page 7 of 36 ADSC 85 B4 A8 Input- Synchronous Address Strobe from Controller, sampled on the rising edge of CLK, active LOW. When asserted LOW, addresses presented to the device are captured in the address registers. A1: A0 are also loaded into the burst counter. When ADSP and ADSC are both asserted, only ADSP is recognized. ZZ 64 T7 H11 Input- Asynchronous ZZ “sleep” Input, active HIGH. When asserted HIGH places the device in a non-time-critical “sleep” condition with data integrity preserved. For normal operation, this pin has to be LOW or left floating. ZZ pin has an internal pull-down.

As inputs, they feed into an on-chip data register that is triggered by the rising edge of CLK. As outputs, they deliver the data contained in the memory location specified by the addresses presented during the previous clock rise of the read cycle. The direction of the pins is controlled by OE. When OE is asserted LOW, the pins behave as outputs. When HIGH, DQs and DQPX are placed in a tri-state condition.

MODE 31 R3 R1 Input- Static Selects Burst Order. When tied to GND selects linear burst sequence. When tied to VDD or left floating selects interleaved burst sequence. This is a strap pin and should remain static during device operation. Mode Pin has an internal pull-up. TDO - U5 P7 JTAG serial output Synchronous Serial data-out to the JTAG circuit. Delivers data on the negative edge of TCK. If the JTAG feature is not being utilized, this pin should be disconnected. This pin is not available on TQFP packages.
