AK63232Z

32,768 x 32 Bit CMOS / BiCMOS

Static Random Access Memory

DESCRIPTION

The Accutek AK63232Z SRAM Module consists of fast high perfor-

mance SRAMs mounted on a low profile, 64 pin ZIP Board. The

module utilizes four 28 pin 32K x 8 SRAMs in 300 mil SOJ packages

and four decoupling capacitors mounted on the front side of a

printed circuit board.

64-Pin ZIP

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 8 nSEC to 45 nSEC

in CMOS or BiCMOS technology.

The Accutek module is designed to have a maximum seated height

of 0.500 inch. The module conforms to JEDEC-standard sizes and

pin-out configurations. This, along with use of two pins for module

memory density identification, PD₀and PD₁, minimizes

interchangeability and design considerations when changing from

one module size to the other in customer applications.

· Upward compatible with 64K x 32 (AK63264), 256K x 32
