65,536 x 24 Bit CMOS/BiCMOS
Static Random Access Memory
DESCRIPTION
64-Pin ZIP
The Accutek AK62464 SRAM Module consists of fast high performance SRAMs mounted on a low profile, 64 pin ZIP Board. The
module utilizes six 28 pin 64K x 4 SRAMs in 300 mil SOJ packages
and three decoupling capacitors mounted on the top side and two
28 pin 64K x 4 SRAMs in 300 mil SOJ packages and three decoupling capacitors mounted on the bottom side of a printed circuit
board.

The SRAMs used have common I/O functions and single output enable functions. Also, three separate chip select (CE) connections
are used to independently enable the three bytes. The modules can
be supplied in a variety of access time values from 8nSEC to
20nSEC in CMOS or BiCMOS technology.
The Accutek module is designed to have a maximum seated height
of 0.500 inch to provide for the lowest height off the board. The
modules conform 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.
