8M-WORD BY 72-BIT

SYNCHRONOUS DYNAMIC RAM MODULE (SO DIMM)

Description

The MC-458CA721ESA, MC-458CA721PSA and 458CA721XSA are 8,388,608 words by 72 bits synchronous

dynamic RAM module (Small Outline DIMM) on which 5 pieces of 128M SDRAM: µPD45128163 are assembled.

These modules provide high density and large quantities of memory in a small space without utilizing the surface-

mounting technology on the printed circuit board.

Decoupling capacitors are mounted on power supply line for noise reduction.

Features

• 8,388,608 words by 72 bits organization (ECC type)

• Clock frequency and access time from CLK
