|Datasheet||Download AK632256W datasheet
The Accutek AK632256 SRAM Module consists of eight 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 mounted 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 0.680 inch SIM or 0.540 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 another in customer applications.FEATURES
