ACCUTEK
MICROCIRCUIT CORPORATION
DESCRIPTION
The Accutek AK682048D high density memory module is a static
random access memory organized in 2 Meg x 8 bit words. The as-
sembly consists of one medium speed 2 Meg x 8 SRAM in a Type 1
TSOP package. The module is supplied in a 600 mil wide, 36 pin
DIP (Dual In-Line Package) configuration. This pinout is completely
compatible with industry standard monolithic designs. These mod-
ules are intended for use in applications where limited board space
dictates compact module designs.
The operation of the AK682048D is identical to standard monolithic
8 bit word wide SRAMs.
The AK682048D offers the features of low power and medium
speed by using CMOS devices and makes high density mounting
possible with no surface mount technology.
FEATURES
• 2,097,152 x 8 bit organization
• Fast access time: 45 - 70 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 - AK682048D
• Single 3.3 volt power supply - AK682048D/3.3
• Operating free air temperature 00 to 700C

ELECTRICAL SPECIFICATIONS
Timing diagrams and basic electrical characteristics are those of
the standard 2048 Meg x 8 SRAMs used to construct these mod-
ules. Accutek’s module design allows the flexibility of selecting in-
dustry-compatible 2048 Meg x 8 SRAMs from any of a number of
semiconductor manufacturers.
