AK63264AW 65,536 x 32 Bit CMOS/BiCMOS Static Random Access Memory ACCUTEK MICROCIRCUIT CORPORATION DESCRIPTION The Accutek AK63264A SRAM Module consists of fast high performance SRAMs mounted on a low height, 64 pin SIM or ZIP Board. The module utilizes four 32 pin 64K x 8 SRAMs in 300 mil SOJ packages and four decoupling capacitors mounted on the front side of a printed circuit board. Front View 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 12nSEC to 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.
