DATA SHEET 512MB Unbuffered DDR2 SDRAM DIMM EBE51UD8AGFA (64M words × 64 bits, 1 Rank) Description Features The EBE51UD8AGFA is 64M words × 64 bits, 1 rank DDR2 SDRAM unbuffered 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 highspeed data transfer is realized by the 4 bits prefetchpipelined 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. • 240-pin socket type dual in line memory module (DIMM) PCB height: 30.0mm Lead pitch: 1.0mm 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.

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 A13 (input pins) Row address (AX0 to AX13) is determined by the A0 to the A13 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) [Bank Select Signal Table] BA0 BA1 Bank 0 L L Bank 1 H L Bank 2 L H Bank 3 H H 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). Data Sheet E0781E20 (Ver. 2.0) 19 EBE51UD8AGFA 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.

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.
