MC-4516CA727XFA

DATA SHEET MOS INTEGRATED CIRCUIT MC-4516CA727XFA 16M-WORD BY 72-BIT SYNCHRONOUS DYNAMIC RAM MODULE UNBUFFERED TYPE Description The MC-4516CA727XFA is 16,777,216 words by 72 bits synchronous dynamic RAM module on which 9 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.
