AK63264Z

MICROCIRCUIT CORPORATION DESCRIPTION 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 eight 28 pin 64K 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. 1 ACCUTEK AK63264W/AK63264Z 65,536 x 32 Bit CMOS/BiCMOS Static Random Access Memory Front View 64-Pin SIM + + 1 32 33 64 64-Pin ZIP 32 33 64 · Presence Detect, PD0 and PD1 for identifying module density · Fast Access Times range from 12 nSEC BiCMOS to 45 nSEC CMOS · TTL-compatible inputs and outputs · Single 5 volt power supply - AK63264W, AK63264Z · Sin...
