ACCUTEK AK63264BZ_09

AK63264BZ
65,536 x 32 Bit CMOS/BiCMOS
Static Random Access Memory
ACCUTEK
MICROCIRCUIT CORPORATION
DESCRIPTION
The Accutek AK63264BZ 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 0.520 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.
