Description
Features
The SYS32512ZK/LK is plastic 16Mbit Static
RAM Module housed in a 72 pin plastic SIMM, ZIP
package organised as 512K x 32. The module
utilises four fast 512K x 8 SRAMs housed in SOJ
packages, mounted on one side of an FR4 epoxy
substrate to achieve a very high density module.
•
•
•
•
Very Fast Access Times of 012/015/017 ns.
72 Pin ZIP, SIMM package
5 Volt Supply ± 10%.
Low Power Dissipation:
Operational
Standby (TTL)
4.18 W (maximum).
220 mW (maximum).
The module has four Chip Selects, which when
used correctly allow reading and writing to
individual bytes or words. The pins PD0-3, are
used to identify module memory density in
applications where alternative modules can be
interchanged.
