Description
Features
The SYS32256 is a plastic 8M Static RAM Module
offered in 64 pin ZIP and 64 lead SIMM package,
organised as 256K x 32. The module utilises eight
very fast SRAMs housed in SOJ packages, and
uses double sided surface mount techniques, to
achieve a very high density module.
Four chip selects are used to independently enable
the four bytes. Reading or Writing is executed on
individual or any combination of multiple bytes. Two
pins PD0 & PD1 are used to identify module
memory density where alternative versions of the
JEDEC standard modules can be interchanged.
Access Times of 020/25/30/35 ns.
64 Pin ZIP & SIMM JEDEC standard pinouts.
5 Volt Supply ± 10%.
Power Dissipation 35ns:
Operating (32bit mode)
6.60 W (maximum).
Standby (CMOS) -L
4.40 mW (maximum).
Completely Static Operation.
Equal Access and Cycle Times.
All Inputs and Outputs Directly TTL Compatible.
On-board Supply Decoupling Capacitors.
