AK68512D

MICROCIRCUIT CORPORATION DESCRIPTION The Accutek AK68512D high density memory module is a static random access memory organized in 512K x 8 bit words. The assembly consists of two medium speed 128K x 8 SRAMs in thin TSOP packages and a CMOS decoder logic IC mounted on the top side and two medium speed 128K x 8 SRAMs in thin TSOP packages mounted on the bottom surfaces of a printed circuit board. The module is supplied in a 600 mil wide,32 pin DIP (Dual In-Line Package) configuration. This pinout is completely compatible with forthcoming industry standard monolithic designs. These modules are intended for use in applications where limited board space dictates compact module designs. The operation of the AK68512D is identical to standard monolithic 8 bit word wide SRAMs. The AK68512D offers the features of low power and medium speed by using CMOS devices and makes high density mounting possible with no surface mount technology. p To w Vie ACCUTEK AK68512D 524,288 x 8 Bit CMOS Static Random Access Memory 1 tt Bo om w Vie 1 · Operating free air temperature 00 to 700C FEATURES · 524,288 x 8 bit organization · Fast access time: 85 - 120 nSEC · Completely static RAM, no clock or timing strobe required · Inputs and outputs TTL compatible · Conventional 600 mil wide SIP package with industry compatible pinout · Single 5 volt power supply - AK68512D · Single 3.3 volt power supply - AK68512D/3.3 ELECTRICAL SPECIFICATIONS Timing diagrams and basic electrical characteristics are ...
