Description The MC-4532DA727 is an 33,554,432 words by 72 bits synchronous dynamic RAM module on which 18 pieces of 128M SDRAM: µPD45128441 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. Features • 33,554,432 words by 72 bits organization (ECC type) • Clock frequency and access time from CLK.
