Accutek AK63216Z 16,384 x 32 Bit CMOS / BiCMOS Microcircuit Static Random Access Memory Corporation DESCRIPTION The Accutek AK63216Z SRAM Module consists of fast high perfor- mance SRAMs mounted on a low profile, 64 pin ZIP Board. The Top View module utilizes four 28 pin 32K x 8 SRAMs in 300 mil SOJ packages 64-Pin ZIP and four decoupling capacitors mounted on the front side of a printed circuit board. Eliminating Pin 30 makes a 16K x 32 bit mod- ule using four 32K x 8 SRAMs. The SRAMs used have common I/O functions and single output en- able functions. Also, four separate chip select (CE) connections are used to independently enable the four bytes. The modules can be 1 32 33 64 supplied in a variety of access time values from 8 nSEC to 45 nSEC in CMOS or BiCMOS technology. The Accutek module is designed to have a maximum seated height of 0.500 inch. The module conforms to JEDEC-standard sizes and pin-out configurations.
