GENERAL DESCRIPTION
Micross Components AS5SP512K18 is a 9.0Mb High
Performance Synchronous Pipeline Burst SRAM, available
in multiple temperature screening levels, fabricated using
High Performance CMOS technology and is organized as
a 512K x 18. It integrates address and control registers,
a two (2) bit burst address counter supporting four (4)
double-word transfers. Writes are internally self-timed and
synchronous to the rising edge of clock.
The AS5SP512K18 includes advanced control options
including Global Write, Byte Write as well as an
Asynchronous Output enable. Burst Cycle controls
are handled by three (3) input pins, ADV\, ADSP\ and
ADSC\. Burst operation can be initiated with either the
Address Status Processor (ADSP\) or Address Status Cache
controller (ADSC\) inputs. Subsequent burst addresses are
generated internally in the system’s burst sequence control
block and are controlled by Address Advance (ADV\)
control input.

*Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS
may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other conditions greater than
those indicated in the operational sections of this specification is not implied.
Exposure to absolute maximum conditions for any duration or segment of time
may affect device reliability.
