EBS25UC8APFA (32M words × 64 bits, 1 bank)
Description
The EBS25UC8APFA is 32M words × 64 bits, 1 bank Synchronous Dynamic RAM Registered Module, mounted 8 pieces of 256M bits SDRAM sealed in TSOP package. This module provides high density and large quantities of memory in a small space without utilizing the surface mounting technology. Decoupling capacitors are mounted on power supply line for noise reduction.
