AKCM6432T

512KB SECONDARY CACHE MODULE

FOR THE PENTIUM CPU AND 82430 PCISETS

FEATURES

• 64K x 64 Configuration

• 16K x 11 Tag SRAM Field

• Low profile card edge module with 160 leads

• Separate 5V and 3.3V power supplies

• Multiple GND pins and decoupling capacitors for maximum noise immunity.

• Synchronous SRAM with Burst Counter

DESCRIPTION

The AKCM6432T Module uses four 32K x 32 pipelined burst RAMs in surface

mount packages mounted on a multi-layer FR4 board. In addition, it uses two 5V 8 -bit

wide SRAMs to achieve an eleven bit tag field. Four PD (presence detect) input pins

allow the system to determine the particular cache configuration. The low profile card

edge package allows 160 single leads to be placed on a package 4.35” long, a

maximum of 0.350” thick and a maximum of 1.14” tall. All inputs and outputs are TLL-

compatible, and operate from separate 5V (+/- 5%) and 3.3V (+10/-5%) power supplies.

Multiple GND pins and on-board decoupling capacitors ensure maximum protection

from noise.
