PRELIMINARY

CYM74BP54

CYM74P54/55

CYM74SP54/55

Intel® 82430NX Chipset

Level II Cache Module Family

Features

• Pin-compatible secondary cache module family

• Asynchronous (CYM74BP54), synchronous pipelined

(CYM74P54, CYM74P55), or synchronous

(CYM74SP54, CYM74SP55) configurations with pres-

ence and configuration detect pins

• Ideal for Intel® P54C-based systems with the 82430NX

(Neptune) chipset

• Operates at 60 and 66 MHz

• Uses cost-effective CMOS asynchronous SRAMs or

high-performance synchronous SRAMs

• 160-position Burndy DIMM CELP2X80SC3Z48

connector

• 3.3V inputs/outputs

dustry standard 5V SRAMs and 3.3V level translators for CPU

bus speeds up to 66 MHz. The CYM74BP54 is organized as

32K by 64-bits.

The synchronous modules are available with low-cost syn-

chronous pipelined RAMs or higher performance synchronous

burst RAMs. The synchronous pipelined modules are based

on a 16Kx64 RAM. The CYM74P54 is a 256-KB module while

the CYM74P55 is a 512-KB module. Both are modules without

byte parity.

The CYM74SP54 and CYM74SP55 are synchronous burst

cache modules that provide zero wait-state performance at a

bus speed of 66 MHz. The CYM74SP54 is a 256-Kbyte cache

module with byte parity. The CYM74SP55 is a 512-Kbyte

cache module with byte parity.

Multiple ground pins and on-board decoupling capacitors en-

sure high performance with maximum noise immunity.

All components on the cache modules are surface mounted

on a multi-layer epoxy laminate (multifunctional) substrate.

The contact pins are plated with 150 micro-inches of nickel

covered by 10 micro-inches of gold flash.

Functional Description

This family of secondary cache modules is designed for Intel

P54C systems with the 82430NX (Neptune) chipset.

CYM74BP54 is an asynchronous 256-Kbyte cache module

that provides a low-cost, high-performance solution with in-
