Static Random Access Memory
DESCRIPTION
Front View
The Accutek AK631024 SRAM Module consists of fast high perfor-
mance SRAMs mounted on a low profile, 72 pin SIM or ZIP PCB.
The module utilizes four 32 pin 1 Meg x 4 SRAMs in 400 mil SOJ
packages and four decoupling capacitor chips mounted on each
side of a printed circuit board.

The SRAMs used have common I/O functions and single output en-
able functions. Also, four separate chip select (CE) connections are
used to independently enable the four bytes. The modules can be
supplied in a variety of access time values from 15nSEC to 30nSEC
in CMOS or BiCMOS technology.
72-Pin ZIP
The Accutek module is designed to have a maximum seated height
of 0.670 inch SIM or 0.550 inch ZIP to provide for the lowest height
off the board. Each conforms to JEDEC-standard sizes and pin-out
configurations. Using four pins for module memory density identifi-
cation, PC0, PD1, PD2 and PD3 minimizes interchangeability and
design considerations when changing from one module size to the
other in customer applications.
