General Description

The EBE25EC8AAFA is 32M words × 72 bits, 1 rank DDR2 SDRAM unbuffered module, mounting 9 pieces of 256M bits DDR2 SDRAM sealed in FBGA (µBGA) package.

Read and write operations are performed at the cross points of the CK and the /CK.

This highspeed data transfer is realized by the 4 bits prefetchpipelined architecture.

Key Features

240-pin socket type dual in line memory module (DIMM)  PCB height: 30.0mm  Lead pitch: 1.0mm  Lead-free.
1.8V power supply.
Data rate: 533Mbps/400Mbps (max. ).
1.8V (SSTL_18 compatible) I/O.
Double-data-rate architecture: two data transfers per clock cycle.
Bi-directional, differential data strobe (DQS and /DQS) is transmitted/received with data, to be used in capturing data at the receiver.
DQS is edge aligned with data for READs.
