1240pin DDR2 SDRAM Unbuffered DIMMs
Input/Output Functional Description
Symbol Type Polarity Pin Description
CK[2:0], CK[2:0] SSTL Differential
Crossing
CK and /CK are differential clock inputs. All the DDR2 SDRAM addr/cntl inputs are sam-
pled on the crossing of positive edge of CK and negative edge of /CK. Output(read) data
is reference to the crossing of CK and /CK (Both directions of crossing)
CKE[1:0] SSTL Active High Activates the DDR2 SDRAM CK signal when high and deactivates the CK signal when
low. By deactivating the clocks, CKE low initiates the Power Down mode or the Self
Refresh mode.
S[1:0] SSTL Active Low
Enables the associated DDR2 SDRAM command decoder when low and disables the
command decoder when high. When the command decoder is disabled, new commands
are ignored but previous operations continue. Rank 0 is selected by S0; Rank 1 is
selected by S1
RAS, CAS,
WE SSTL Active Low /RAS,/CAS and /WE(ALONG WITH S) define the command being entered.
ODT[1:0] SSTL Active High Asserts on-die termination for DQ, DM, DQS and DQS signals if enabled via the DDR2
SDRAM mode register.
Vref Supply Reference voltage for SSTL18 inputs
VDDQ Supply Power supplies for the DDR2 SDRAM output buffers to provide improved noise immu-
nity . For all current DDR2 unbuffered DIMM designs, VDDQ shares the same power plane
as VDD pins.
BA[2:0] SSTL - Selects which DDR2 SDRAM internal bank of four or eight is activated.
A[9:0], A10/AP,
A[13:11] SSTL -
During a Bank Activate command cycle, Address input defines the row
address(RA0~RA15)
During a Read or Write command cycle, Address input defines the column address when
sampled at the cross point of the rising edge of CK and falling edge of CK. In addition to
the column address, AP is used to invoke autoprecharge operation at the end of the
burst read or write cycle. If AP is high., autoprecharge is selected and BA0-BAn defines
the bank to be precharged. If AP is low, autoprecharge is disabled. During a Precharge
command cycle., AP is used in conjunction with BA0-BAn to control which bank(s) to
precharge. If AP is high, all banks will be precharged regardless of the state of BA0-BAn
inputs. If AP is low, then BA0-BAn are used to define which bank to precharge.
DQ[63:0],
CB[7:0] SSTL - Data and Check Bit Input/Output pins.
DM[8:0] SSTL Active High
DM is an input mask signal for write data. Input data is masked when DM is sampled
High coincident with that input data during a write access. DM is sampled on both edges
of DQS. Although DM pins are input only, the DM loading matches the DQ and DQS
loading.
VDD,VSS Supply Power and ground for the DDR2 SDRAM input buffers, and core log ic. VDD and VDDQ
pins are tied to VDD/VDDQ planes on these modules.
DQS[8:0],
DQS[8:0] SSTL Differential
crossing
Data strobe for input and output data. For Rawcards using x16 organized DRAMs,
DQ0~7 connect to the LDQS pin of the DRAMs and DQ8~15 connect to the UDQS pin of
the DRAM
SA[2:0] - These signals are tied at the system planar to either VSS or VDD to configure the serial
SPD EEPROM.
SDA - This is a bidirectional pin used to transfer data into or out of the SPD EEPROM. A
resister must be connected to VDD to act as a pull up.
SCL - This signal is used to clock data into and out of the SPD EEPROM. A resistor may be
connected from SCL to VDD to act as a pull up on the system board.
VDDSPD Supply Power supply for SPD EEPROM. This supply is separate from the VDD/VDDQ power
plane. EEPROM supply is operable from 1.7V to 3.6V.

ABSOLUTE MAXIMUM RATINGS
Operation Conditions and Environmental Parameters
Notes:
1. S tress greater than those listed may cause permanent damage to the device. This is a stress rating only, and device
functional operation at or above th e conditions indicated is not implied. Exposure to absolute maximum rating con
ditions for extended periods may affect reliability.
2. Up to 9850 ft.
3. If the DRAM case te mp e rature is Above 85oC, the Auto-Refresh command interval has to be reduced to
tREFI=3.9us. For Measurement conditio ns of TCASE, please refer to the JEDEC document JESD51-2.
DC OPERATING CONDITIONS (SSTL_1.8)
Notes:
1. Min. Type. and Max. values increase by 100mV for C3(DDR2-533 3-3-3) speed option.
2. VDDQ tracks with VDD,VDDL tracks with VDD. AC parameters are measured with VDD,VDDQ and VDD.
3. The value of VREF may be selected by the user to provide optimum noise margin in the system. Typically the
value of VREF is expected to be about 0.5 x VDDQ of the transmitting device and VREF is expected to track vari-
ations in VDDQ.
4. Peak to peak ac noise on VREF may not exceed +/-2% VREF (dc).
5. VTT of transmitting device must track VREF of receiving device.

AC INPUT TEST CONDITIONS
Notes:
1. Input waveform timing is referenced to the input signal crossing through the VREF level appl ied to the device
under test.
2. The input signal minimum slew rate is to be maintained over the range from VREF to VIH(ac) min for rising edges
and the range from VREF to VIL(ac) max for fallin g edges as shown in the below figure.
3. AC timings are referenced with input waveforms switching from VIL(ac) to VIH(ac) on the positive transitions and
VIH(ac) to VIL(ac) on the negative transitions.

Differential Input AC logic Level
1. VIN(DC) specifies the allowable DC execution of each input of differential pair such as CK, CK, DQS, DQS, LDQS,
LDQS, UDQS and UDQS.
2. VID(DC) specifies the input differential voltage |VTR -VCP | required for switching , whe re VTR is the true input
(such as CK, DQS, LDQS or UDQS) level and VCP is the complementary input (such as CK, DQS, LDQS or UDQS)
level. The minimum value is equal to VIH(DC) - VIL(DC).
Notes:
1. VID(AC) specifies the input differential voltage |VTR -VCP | required for switching, where VTR is the true input signal
(such as CK, DQS, LDQS or UDQ S) and VCP is the complementary input signal (such as CK, DQS, LDQS or UDQS).
The minimum value is equal to V IH(AC) - VIL(AC).
2. The typical value of VIX(AC) is expected to be about 0.5 * VDDQ of the transmitting device and VIX(AC) is expected to
track variations in VDDQ. VIX(AC) indicates the voltage at which differential input signals must cross.
DIFFERENTIAL AC OUTPUT PARAMETERS
Note:
1. The typical value of VOX(AC) is expected to be about 0.5 * VDDQ of the transmitting device and VOX(AC) is expected to
track variations in VDDQ. VOX(AC) indicates the voltage at which differential output signals must cross.

Note:
1. The VDDQ of the device under test is referenced.
OUTPUT DC CURRENT DRIVE
Notes:
1.VDDQ = 1.7 V; VOUT = 1420 mV. (VOUT - VDDQ)/IOH must be less than 21 ohm for values of VOUT between VDDQ and
VDDQ - 280 mV.
2. VDDQ = 1.7 V; VOUT = 280 mV. VOUT/IOL must be less than 21 ohm for values of VOUT between 0 V and 280 mV.
3. The dc value of VREF applied to the receiving device is set to VTT
4. The values of IOH(dc) and IOL(dc) are based on the conditions given in Notes 1 and 2. They are used to test device
drive current capability to ensure VIH min plus a noise margin and VIL max minus a noise margin are delivered to an
SSTL_18 receiver. The actual current values are derived by shifting the desired driver operating point along a 21 ohm
load line to define a convenient driver current for measurement.

HIGH is defined as Vin VIHAC(min)
STABLE is defined as inputs stable at a HIGH or LOW level
FLOATING is defined as inputs at VREF = VDDQ/2
SWITCHING is defined as:
inputs changing between HIGH and LOW every other clock cycle (once per two clocks) for address and control sig-
nals, and inputs changing between HIGH and LOW every other data transfer (once per clock) for DQ signals not
including masks or strobes.
