Input-

Address Strobe from Processor, sampled on

 

ADSP

 

 

 

 

 

 

Synchronous

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.

 

 

 

 

 

 

 

 

ASDP is ignored when CE1 is deasserted HIGH.

Input-

Address Strobe from Controller, sampled on the

 

ADSC

 

 

 

 

 

 

 

 

Synchronous

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

Input-

ZZ “sleep” Input, active HIGH. When asserted

 

 

 

 

 

 

 

Asynchronous

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.

controlled by OE. When OE is asserted LOW, the

DQPX are placed in a tri-state condition.
