MC-458CB647PFA-A75 Product details

Description

The MC-458CB647EFA, MC-458CB647PFA and MC-458CB647XFA are 8,388,608 words by 64 bits synchronous dynamic RAM module on which 4 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.
