AK61664Z-30 - Accutek Microcircuit Corporation

DESCRIPTION

The Accutek AK61664 SRAM Module consists of fast high perfor-

mance SRAMs mounted on a low profile 40 pin ZIP PCB. The mod-

ule utilizes two 28 pin 64K x 4 SRAMs in 300 mil SOJ packages and

two decoupling capacitor chips mounted on each side of a printed

circuit board.

The SRAMs are interconnected on the module to have common I/O

functions, single output enable functions and common chip select.

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 for the lowest height off the board,

consistent with the availability of commonly available SRAM SOJ

package configurations.
