Description
Data input/output: Bidirectional data bus for the x8 configuration. DQ[7:0] are
referenced to V
Data strobe: Output with read data. Edge-aligned with read data. Input with write
data. Center-aligned to write data.
Termination data strobe: Applies to the x8 configuration only. When TDQS is
enabled, DM is disabled, and the TDQS and TDQS# balls provide termination resistance.
Power supply: 1.5V ±0.075V.
DQ power supply: 1.5V ±0.075V. Isolated on the device for improved noise immunity.
Reference voltage for control, command, and address: V
maintained at all times (including self refresh) for proper device operation.
Reference voltage for data: V
refresh) for proper device operation.
Ground.
DQ ground: Isolated on the device for improved noise immunity.
External reference ball for output drive calibration: This ball is tied to an
external 240Ω resistor (RZQ), which is tied to V
No connect: These balls should be left unconnected (the ball has no connection to
the DRAM or to other balls).
No function: When configured as a x4 device, these balls are NF. When configured
as a x8 device, these balls are defined as TDQS#, DQ[7:4].
