DESCRIPTION
64-Pin SIM
The Accutek AK63264 SRAM Module consists of fast high performance SRAMs mounted on a low profile, 64 pin SIM or ZIP Board.
The module utilizes eight 28 pin 64K x 4 SRAMs in SOJ packages
and four decoupling capacitors on each side of a printed circuit
board.

The SRAMs used have common I/O functions and single output enable 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 12 nSEC to
45 nSEC in CMOS or BiCMOS technology.
The Accutek module is designed to have a maximum seated height
of 0.600 inch SIM or 0.500 inch ZIP to provide for the lowest height
off the board. By offset-mounting the back surface SRAMs on the
SIM version the module can be mounted in either angled or
straight-up SIM sockets. Each conforms to JEDEC - standard sizes
and pin-out configurations. Using two pins for module memory density identification, PD0 and PD1, minimizes interchangeability and
design considerations when changing from one module size to the
other in customer applications.
