Features, Applications

The Accutek is a high density SRAM memory module organized in 1 Meg X 8 bit words. The assembly consists of four medium speed 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 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 configuration 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 or 100 nSEC. The combination of low power, low profile and high density packaging 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.
