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.
