MC-428LFH641  
3.3 V OPERATION 8M-WORD BY 64-BIT DYNAMIC RAM MODULE  
UNBUFFERED TYPE, EDO  
Description  
The MC-428LFH641 is a 8,388,608 words by 64 bits dynamic RAM module on which 8 pieces of 64M DRAM :  
PD4264805 are assembled.  
µ
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.
