1,048,576 x 32 Bit CMOS/BiCMOS
Static Random Access Memory
Front View
The Accutek AK631024 SRAM Module consists of fast high performance SRAMs mounted on a low profile, 72 pin SIM or ZIP PCB.
The module utilizes four 32 pin 1 Meg x 4 SRAMs in 400 mil SOJ
packages and four decoupling capacitor chips mounted on each
side of a printed circuit board.
72-Pin SIM
1
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 15nSEC to 30nSEC
in CMOS or BiCMOS technology.
The Accutek module is designed to have a maximum seated height
of 0.670 inch SIM or 0.550 inch ZIP to provide for the lowest height
off the board. Each conforms to JEDEC-standard sizes and pin-out
configurations. Using four pins for module memory density identification, PC0, PD1, PD2 and PD3 minimizes interchangeability and
design considerations when changing from one module size to the
other in customer applications.
FEATURES
· 1,048,576 x 32 SRAM module in high density configuration
· JEDEC Standardized 72 pin SIM format
· Common I/O, single OE functions with four separate chip
selects (CE)
· Low height, 0.670 inch SIM or 0.550 inch ZIP maximum
· Presence Detect PD0 through PC3 for identifying module density
· TTL compatible inputs and outputs
· Single 5 volt power supply - AK6321024W, AK6321054Z
· Single 3.3 volt power supply - AK6321024W/3.3,
AK6321024Z/3.3
· Fast access times range from 15 nSEC BiCMOS to 25 nSEC
