Features, Applications

The Accutek AK63264 SRAM Module consists of fast high performance SRAMs mounted on a low profile, 64 pin SIM or ZIP Board. The module utilizes four 28 pin x 4 SRAMs in SOJ packages and four decoupling capacitors on each 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 12 nSEC to 45 nSEC in CMOS or BiCMOS technology. The Accutek module is designed to have a maximum seated height of 0.600 inch SIM or 0.500 inch ZIP to provide for the lowest height off the board. By offset-mounting the back surface SRAMs on the SIM version the module can be mounted in either angled or straight-up SIM sockets. Each conforms to JEDEC - standard sizes and pin-out configurations. Using two pins for module memory density identification, PD0 and PD1, minimizes interchangeability and design considerations when changing from one module size to the other in customer applications.

Timing diagrams and basic electrical characteristics are those of the standard x 4 SRAMs used to construct these modules. Accutek's module design allows the flexibility of selecting industry-compatible x 4 SRAMs from at least seven semiconductor manufacturers.
