MC-4532CD646

DATA SHEET MOS INTEGRATED CIRCUIT MC-4532CD646 32M-WORD BY 64-BIT SYNCHRONOUS DYNAMIC RAM MODULE UNBUFFERED TYPE Description The MC-4532CD646 is a 33,554,432 words by 64 bits synchronous dynamic RAM module on which 16 pieces of 128M SDRAM: µPD45128841 are assembled. This module provides high density and large quantities of memory in a small space without utilizing the surfacemounting technology on the printed circuit board. Decoupling capacitors are mounted on power supply line for noise reduction.
