Features, Applications

The Accutek AK632128W SRAM Module consists of fast high performance SRAMs mounted on a low height, 64 pin SIM or ZIP PCB. The module utilizes 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 SIM or 0.520 inch ZIP to provide for the lowest height off the board. Each conforms to JEDEC-standard sizes and pin-out configurations. Using two pins for module denisty identification, PD0 and PD1, minimizes interchangeability and design considerations when changing from one module size to the other in customer applications.

Common I/O, single OE functions with four separate chip selects (CE) Presence Detect PD0 and PD1 for identifying module density Downward compatible with 32 (AK63232) and 32 AK63264) Upward compatible with 32 (AK632512) and 1 Meg 32 (AK6321024) Operating free air temperature to 700C

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 at least seven semiconductor manufacturers.
