DATA SHEET
512MB DDR2 SDRAM SO-DIMM
EBE52UD6AFSA (64M words × 64 bits, 2 Ranks)
Description
Features
The EBE52UD6AFSA 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.
• 200-pin socket type small outline dual in line memory
module (SO-DIMM)
 PCB height: 30.0mm
 Lead pitch: 0.6mm
 Lead-free (RoHS compliant)
• Power supply: VDD = 1.8V ± 0.1V
• Data rate: 667Mbps/533Mbps/400Mbps (max.)
• 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: centeraligned 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
(Components)
• 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
• Average refresh period
 7.8µs at 0°C ≤ TC ≤ +85°C
 3.9µs at +85°C < TC ≤ +95°C
• Posted CAS by programmable additive latency for
better command and data bus efficiency
• Off-Chip-Driver Impedance Adjustment and On-DieTermination for better signal quality
• /DQS can be disabled for single-ended Data Strobe
operation.
Note: Do not push the components or drop the
modules in order to avoid mechanical defects,
which may result in electrical defects.

IDD specifications are tested after the device is properly initialized.
Input slew rate is specified by AC Input Test Condition.
IDD parameters are specified with ODT disabled.
Data bus consists of DQ, DM, DQS, /DQS, RDQS, /RDQS, LDQS, /LDQS, UDQS, and /UDQS. IDD
values must be met with all combinations of EMRS bits 10 and 11.
5. Definitions for IDD
L is defined as VIN ≤VIL (AC) (max.)
H is defined as VIN ≥VIH (AC) (min.)
STABLE is defined as inputs stable at an H or L level
FLOATING is defined as inputs at VREF = VDDQ/2
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.

Pin Functions
CK, /CK (input pin)
The CK and the /CK are the master clock inputs. All inputs except DMs, DQSs and DQs are referred to the cross
point of the CK rising edge and the VREF level. When a read operation, DQSs and DQs are referred to the cross
point of the CK and the /CK. When a write operation, DMs and DQs are referred to the cross point of the DQS and
the VREF level. DQSs for write operation are referred to the cross point of the CK and the /CK.
/CS (input pin)
When /CS is low, commands and data can be input. When /CS is high, all inputs are ignored. However, internal
operations (bank active, burst operations, etc.) are held.
/RAS, /CAS, and /WE (input pins)
These pins define operating commands (read, write, etc.) depending on the combinations of their voltage levels.
See "Command operation".
A0 to A12 (input pins)
Row address (AX0 to AX12) is determined by the A0 to the A12 level at the cross point of the CK rising edge and the
VREF level in a bank active command cycle. Column address (AY0 to AY9) is loaded via the A0 to the A9 at the
cross point of the CK rising edge and the VREF level in a read or a write command cycle. This column address
becomes the starting address of a burst operation.
A10 (AP) (input pin)
A10 defines the precharge mode when a precharge command, a read command or a write command is issued. If
A10 = high when a precharge command is issued, all banks are precharged. If A10 = low when a precharge
command is issued, only the bank that is selected by BA1, BA0 is precharged. If A10 = high when read or write
command, auto-precharge function is enabled. While A10 = low, auto-precharge function is disabled.
BA0 and BA1 (input pins)
BA0, BA1 are bank select signals (BA). The memory array is divided into bank 0, bank 1, bank 2 and bank 3. (See
Bank Select Signal Table)

Remark: H: VIH. L: VIL.
CKE (input pin)
CKE controls power down and self-refresh. The power down and the self-refresh commands are entered when the
CKE is driven low and exited when it resumes to high.
The CKE level must be kept for 1 CK cycle at least, that is, if CKE changes at the cross point of the CK rising edge
and the VREF level with proper setup time tIS, at the next CK rising edge CKE level must be kept with proper hold
time tIH.
DQ (input and output pins)
Data are input to and output from these pins.
DQS and /DQS (input and output pin)
DQS and /DQS provide the read data strobes (as output) and the write data strobes (as input).

EBE52UD6AFSA
DM (input pins)
DM is the reference signal of the data input mask function. DMs are sampled at the cross point of DQS and /DQS.
VDD (power supply pins)
1.8V is applied. (VDD is for the internal circuit.)
VDDSPD (power supply pin)
1.8V is applied (For serial EEPROM).
VSS (power supply pin)
Ground is connected.

CAUTION FOR HANDLING MEMORY MODULES
When handling or inserting memory modules, be sure not to touch any components on the modules, such as
the memory ICs, chip capacitors and chip resistors. It is necessary to avoid undue mechanical stress on
these components to prevent damaging them.
In particular, do not push module cover or drop the modules in order to protect from mechanical defects,
which would be electrical defects.
When re-packing memory modules, be sure the modules are not touching each other.
Modules in contact with other modules may cause excessive mechanical stress, which may damage the
modules.
MDE0202
NOTES FOR CMOS DEVICES
1
PRECAUTION AGAINST ESD FOR MOS DEVICES
Exposing the MOS devices to a strong electric field can cause destruction of the gate
oxide and ultimately degrade the MOS devices operation. Steps must be taken to stop
generation of static electricity as much as possible, and quickly dissipate it, when once
it has occurred. Environmental control must be adequate. When it is dry, humidifier
should be used. It is recommended to avoid using insulators that easily build static
electricity. MOS devices must be stored and transported in an anti-static container,
static shielding bag or conductive material. All test and measurement tools including
work bench and floor should be grounded. The operator should be grounded using
wrist strap. MOS devices must not be touched with bare hands. Similar precautions
need to be taken for PW boards with semiconductor MOS devices on it.
2
HANDLING OF UNUSED INPUT PINS FOR CMOS DEVICES
No connection for CMOS devices input pins can be a cause of malfunction. If no
connection is provided to the input pins, it is possible that an internal input level may be
generated due to noise, etc., hence causing malfunction. CMOS devices behave
differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed
high or low by using a pull-up or pull-down circuitry. Each unused pin should be connected
to VDD or GND with a resistor, if it is considered to have a possibility of being an output
pin. The unused pins must be handled in accordance with the related specifications.
3
STATUS BEFORE INITIALIZATION OF MOS DEVICES
Power-on does not necessarily define initial status of MOS devices. Production process
of MOS does not define the initial operation status of the device. Immediately after the
power source is turned ON, the MOS devices with reset function have not yet been
initialized. Hence, power-on does not guarantee output pin levels, I/O settings or
contents of registers. MOS devices are not initialized until the reset signal is received.
Reset operation must be executed immediately after power-on for MOS devices having
reset function.
