Function
Positive line of the differential pair of system clock inputs. (All DDR2 SDRAM address and
control inputs are sampled on the rising edge of their associated clocks. Output data is ref-
erenced at the crossings of the clocks.)
Negative line of the differential pair of system clock inputs.
On-Die Termination: ODT when high enables termination resistance internal to the DDR2
SDRAM. When enabled, ODT is only applied to each of the following pins: DQ, DQS, and
DM. The ODT input will be ignored if disabled in Extended Mode Register (EMRS).
Activates the DDR2 SDRAM CLK signal when high and deactivates the CLK signal when
low. By deactivating the clocks, CKE low initiates the Power Down mode, or the Self
Refresh mode.
Enables the associated DDR2 SDRAM command decoder when low and disables decoder
when high. When decoder is disabled, new commands are ignored but previous operations
continue.
When sampled at the positive rising edge of the clock, CAS#, RAS#, and WE# define the
operations to be executed by the SDRAM.
Bank Address define to which bank an Activate, Read, Write or Precharge command is
being applied. Bank address also determines if the Mode Register or Extended Mode Reg-
ister is to be accessed during a MRS or EMRS cycle.

Function
During a Bank Activate command cycle, A0-A13 defines the row address (RA0-RA13)
when sampled at the rising clock edge.
During a Read or Write command cycle, A0-A9, A11 defines the column address (CA0-
CA9, CA11) when sampled at the rising clock edge. In addition to the column address,
A10/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~BA2 defines the bank to be pre-
charged. If AP is low, autoprecharge is disabled.
During a Precharge command cycle, A10/AP is used in conjunction with BA0~BA2 to con-
trol which bank(s) to precharge. If AP is high, all banks will be precharged regardless of the
state of BA0~BA2. If AP is low, BA0~BA2 are used to define which bank to precharge. The
address inputs also provide the op-code during Mode Register Set commands.
Data and Check Bit Input/Output pins.
DDR2 SDRAM differential data strobe for input and output data.
DDR2 SDRAM differential data strobe for input and output data.
Slave Address Select for EEPROM. These pins are used to configure the presence-detect
device.
Serial Bus Data Line for EEPROM. SDA is a bidirectional pin used to transfer addresses
and data into and out of the presence-detect portion of the module. A resistor must be con-
nected from the SDA bus line to V
DD
to act as pull up on the system board.
Serial Bus Clock for EEPROM. SCL is used to synchronize the presence-detect data trans-
fer to and from the module. A resistor may be connected from the SCL bus line to V
DD
to
act as pull up on the system board.
Register and PLL control pin. When low, all register outputs will be driven low and the PLL
clocks to the DRAM and register will be set to low levels (the PLL will remain synchronized
with the input clock, if within spec range).
SDRAM positive power supply. 1.8V±0.1V
Power supply return (ground).
SDRAM I/O reference supply.
SDRAM I/O Driver positive power supply.1.8V±0.1V
Serial EEPROM positive power supply (wired to a separate power pin at the connector
which supports operation from 1.7V to 3.6V).
No Connection.
