Static Random Access Memory

DESCRIPTION

64-Pin ZIP

The Accutek AK62464 SRAM Module consists of fast high perfor-

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

module utilizes four 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 decoup-

ling capacitors mounted on the bottom side of a printed circuit

board.

The SRAMs used have common I/O functions and single output en-

able 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 configura-

tions. 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 appli-

cations.
