512MB DDR2 SDRAM SO-DIMM
EBE52UD6ABSA (64M words × 64 bits, 2 Ranks)
Description
The EBE52UD6ABSA is 64M words × 64 bits, 2 ranks
DDR2 SDRAM Small Outline Dual In-line Memory
Module, mounting 8 pieces of 512M 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 high-speed data transfer is
realized by the 4 bits prefetch-pipelined architecture.
Data strobe (DQS and /DQS) both for read and write
are available for high speed and reliable data bus
design. By setting extended mode register, the on-chip
Delay Locked Loop (DLL) can be set enable or disable.
This module provides high density mounting without
utilizing surface mount technology. Decoupling
capacitors are mounted beside each FBGA (µBGA) on
the module board.
Note: Do not push the components or drop the
modules in order to avoid mechanical defects,
which may result in electrical defects.
Features
• 200-pin socket type small outline dual in line memory
module (SO-DIMM)
PCB height: 30.0mm
Lead pitch: 0.6mm
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: center-
aligned with data for WRITEs
• Differential clock inputs (CK and /CK)
• DLL aligns DQ and DQS transitions with CK
transitions
• Commands entered on each positive CK edge: data
and data mask referenced to both edges of DQS
• Four internal banks for concurrent operation
(Component)
• Data mask (DM) for write data
• Burst lengths: 4, 8
• /CAS Latency (CL): 3, 4, 5
• Auto precharge operation for each burst access
• Auto refresh and self refresh modes
• 7.8µs average periodic refresh interval
• Posted CAS by programmable additive latency for
better command and data bus efficiency
• Off-Chip-Driver Impedance Adjustment and On-Die-
Termination for better signal quality
• /DQS can be disabled for single-ended Data Strobe
operation.

SWITCHING is defined as:
inputs changing between H and L every other clock cycle (once per two clocks) for address and control
signals, and inputs changing between H and L every other data transfer (once per clock) for DQ signals
not including masks or strobes.
