Description

Address inputs: Defines the row and column addresses for READ and WRITE operations. During a MODE

CK.

Bank address inputs: Selects to which internal bank a command is being applied to.

Input clock: CK and CK# are differential input clocks. Addresses and commands are latched on the rising

edge of CK. CK# is ideally 180 degrees out of phase with CK.

Chip select: CS# enables the command decoder when LOW and disables it when HIGH. When the

command decoder is disabled, new commands are ignored, but internal operations continue.

Data input: The DQ signals form the data bus. During READ commands, the data is referenced to both

edges of QK*. During WRITE commands, the data is sampled at both edges of DK.

Input data clock: DK* and DK*# are the differential input data clocks. All input data is referenced to

both edges of DK*. DK*# is ideally 180 degrees out of phase with DK*. For the x36 device, DQ0–DQ17

are referenced to DK0 and DK0# and DQ18–DQ35 are referenced to DK1 and DK1#. For the x9 and x18

devices, all DQ* are referenced to DK and DK#. All DK* and DK*# pins must always be supplied to the

device.

Input data mask: The DM signal is the input mask signal for WRITE data. Input data is masked when DM

is sampled HIGH. DM is sampled on both edges of DK (DK1 for the x36 configuration). Tie signal to

ground if not used.

IEEE 1149.1 clock input: This ball must be tied to V

if the JTAG function is not used.

IEEE 1149.1 test inputs: These balls may be left as no connects if the JTAG function is not used.

Command inputs: Sampled at the positive edge of CK, WE# and REF# define (together with CS#) the

command to be executed.

Input reference voltage: Nominally V

DDQ

/2. Provides a reference voltage for the input buffers.

External impedance (25–60Ω): This signal is used to tune the device outputs to the system data bus

impedance. DQ output impedance is set to 0.2 × RQ, where RQ is a resistor from this signal to ground.

Connecting ZQ to GND invokes the minimum impedance mode.

Output data clocks: QK* and QK*# are opposite polarity, output data clocks. They are free running, and

during READs, are edge-aligned with data output from the memory. QK*# is ideally 180 degrees out of

phase with QK*. For the x36 device, QK0 and QK0# are aligned with DQ0-DQ17, and QK1 and QK1# are

aligned with DQ18-DQ35. For the x18 device, QK0 and QK0# are aligned with DQ0-DQ8, while QK1 and

QK1# are aligned with Q9-Q17. For the x9 device, all DQs are aligned with QK0 and QK0#.

Data valid: The QVLD pin indicates valid output data. QVLD is edge-aligned with QK* and QK*#.

IEEE 1149.1 test output: JTAG output. This ball may be left as no connect if the JTAG function is not

used.

Power supply: Nominally, 1.8V.

DQ power supply: Nominally, 1.5V or 1.8V. Isolated on the device for improved noise immunity.

Power supply: Nominally, 2.5V.

Ground.

DQ ground: Isolated on the device for improved noise immunity.

Power supply: Isolated termination supply. Nominally, V

DDQ

/2.

Reserved for future use: This signal is internally connected.

Reserved for future use: This signal is not connected and can be connected to ground.

Do not use: These balls may be connected to ground. Note that if ODT is enabled, these pins are High-Z.

No function: These balls can be connected to ground.
