DESCRIPTION
The Accutek AK63232W SRAM Module consists of fast high perfor-
mance SRAMs mounted on a low profile, 64 pin SIM Board. The
module utilizes four 28 pin 32K x 8 SRAMs in SOJ packages and
four decoupling capacitor chips on one side of the circuit board.

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
supplied in a variety of access time values from 12 nSEC to
45 nSEC in CMOS or BiCMOS technology.

The Accutek module is designed for the lowest height off the board,
consistent with the availability of commonly available SRAM SOJ
package configurations. Each conforms to JEDEC - standard sizes
and pin-out configurations. This, along with use of two pins for mod-
ule memory density identification, PD0 and PD1, minimizes
interchangeability and design considerations when changing from
one module size to the other in customer applications.
· Upward compatible with 64k x 32, AK63264W, 256K x 32,
AK6322W and 1 meg x 32, AK6321024W designs
· Presence Detect, PD0 and PD1 for identifying module density
FEATURES
· Fast Access Times range from 12 nSEC BiCMOS to 45 nSEC
· 32,768 x 32 bit organization
CMOS
· JEDEC Standardized 64 pin SIM format
· TTL compatible inputs and outputs
· Common I/O, single OE functions with four separate chip
· Single 5 volt power supply - AK63232W
· Single 3.3 volt power supply - AK63232W/3.3
· Operating temperature range in free air, 00C to 700C
selects (CE)
· Low height, 0.600 inch maximum, for mounting in straight-up or
angled SIM sockets
