Address Strobe from Processor, 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.

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 “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.
Bidirectional Data I/O lines. 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
