AK681024G

1,048,579 x 8 Bit CMOS

Static Random Access Memory

DESCRIPTION

The Accutek AK681024G is a high density SRAM memory module

organized in 1 Meg X 8 bit words. The assembly consists of four me-

dium speed 128K X 8 SRAMs in thin TSOP packages, plus a CMOS

decoder logic IC and four decoupling capacitor chips, mounted on

the front side and four medium speed 128K x 8 SRAMS in thin

TSOP packages and four decoupling capacitor chips mounted on

the back side of a low-profile printed circuit board. The module con-

figuration is a 36 pin leaded SIP.

The memory operates as a single asynchronous 1 Meg X 8 SRAM

from a 5V supply, and has common I/O, chip enable, output enable

and write enable functions. With the proper choice of SRAMs, it is

available in three separate low-standby-power configurations, with

access times of 55, 70, 85 or 100 nSEC.

The combination of low power, low profile and high density packag-

ing offered by the AK681024G makes it ideal for use in applications

where board space and available power are limited and extremely

low access times are not required. It is especially useful in VMEbus

designs and in places where very close module-to-module spacing

is dictated.

· Range of access times from 55 to 100 nSEC

· Low, low-low and ultra-low standby power level versions avail-

able

· Single 5 volt power supply - AK681024G

FEATURES

· Single 3.3 volt power supply - AK681024G/3.3

· Operating free air temerature 0⁰C to 70⁰C (Industrial range

· 1,048,576 x 8 bit organization

version of -10⁰C to 85⁰C also available)

· JEDEC Standard 36 pin SIP format

· Common I/O, single OE, CE and WE functions

· Completely static and asynchronous, no clock or timing strobe

required

· Low 0.550 inch maximum seated height and thin profile allow

maximum board density
