DESCRIPTION

Front View

64-Pin SIM

The Accutek AK63264 SRAM Module consists of fast high perfor-

mance SRAMs mounted on a low profile, 64 pin SIM or ZIP Board.

The module utilizes four 28 pin 64K x 4 SRAMs in SOJ packages

and four decoupling capacitors on each side of a printed circuit

board.

32 33

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.

64-Pin ZIP

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 den-

sity identification, PD₀and PD₁, minimizes interchangeability and

design considerations when changing from one module size to the

other in customer applications.

· Upward compatible with 128K x 32 (AK632128), 256K x 32

(AK632256) and 1 Meg x 32 (AK6321024) designs

· Presence Detect, PD₀and PD₁for identifying module density

· Fast Access Times range from 12 nSEC BiCMOS to 45 nSEC

CMOS

· TTL-compatible inputs and outputs

· Single +5 Volt ( 10ꢀ) power supply

· Operating temperature range in free air, 0⁰C to 70⁰C

FEATURES

· 65,536 x 32 bit organization

· JEDEC Standard 64 pin SIM or ZIP format

ELECTRICAL SPECIFICATIONS

· Common I/O, single OE functions with four separate chip

selects (CE)

Timing diagrams and basic electrical characteristics are those of

the standard 64K x 4 SRAMs used to construct these modules.

Accutek’s module design allows the flexibility of selecting indus-

try-compatible 64K x 4 SRAMs from at least seven semiconductor

manufacturers.

· Low height, 0.600 inch SIM or 0.500 inch ZIP maximum
