MC-4532CD647XFA
32M-WORD BY 64-BIT SYNCHRONOUS DYNAMIC RAM MODULE
UNBUFFERED TYPE
Description
The MC-4532CD647XFA is 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 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 64 bits organization
• Clock frequency and access time from CLK.
