MC-458CA726  
8M-WORD BY 72-BIT SYNCHRONOUS DYNAMIC RAM MODULE  
UNBUFFERED TYPE  
Description  
•
The MC-458CA726EFB and MC-458CA726PFB are 8,388,608 words by 72 bits synchronous dynamic RAM module  
on which 5 pieces of 128M SDRAM : µPD45128163 are assembled.  
This module provides 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.
