|Datasheet||Download AK63264AW-12 datasheet
The Accutek AK63264A SRAM Module consists of fast high performance SRAMs mounted on a low height, 64 pin SIM or ZIP Board. The module utilized four 32 pin x 8 SRAMs in 300 mil SOJ packages and four decoupling capacitors mounted on the front side of a printed circuit board. The SRAMs used have common I/O functions and single output enable functions. Also, four separate chip select (CE) connections are used to independently enable the four bytes. The modules can be supplied in a variety of access time values from 35nSEC in CMOS or BiCMOS technology. The Accutek module is designed to have a maximum seated height of 0.600 inch to provide for the lowest height off the board. Each conforms to JEDEC-standard sizes and pin-out configurations. Using two pins for module density identification, PD0 and PD1, minimizes interchangeability and design considerations when changing from one module size to the other in customer applications.
Upward compatible with ( AK632512) and 1 Meg 32 (AK6321024) Fast access times from 12 nSEC TTL-compatible inputs and outputs Single +5 Volt (10%) power supply Operations free air temperature to 700CFEATURES

Timing Diagrams and basic electrical characteristics are those of the standard x 8 SRAMs used to construct these modules. Accutek's module design allows the flexibility of selecting industry-compatible x 8 SRAMs from several semiconductor manufacturers.
