DESCRIPTION
Data Input/Output: Data bus for x8
(DQ4–DQ7 are NC for the x4)
Data Input/Output: Data bus for x4
Data Strobe: Output with read data, input with write data. DQS is edge-
aligned with read data, centered in write data. It is used to capture data.
For the x16, LDQS is DQS for DQ0–DQ7 and UDQS is DQS for DQ8–DQ15.
Pin 16 (E7) is NC on x4 and x8.
No Connect: These pins should be left unconnected.
Do Not Use: Must float to minimize noise on V
DQ Power Supply: +2.5V ±0.2V. Isolated on the die for improved noise
immunity.
DQ Ground. Isolated on the die for improved noise immunity.
Power Supply: +2.5V ±0.2V.
Ground.
SSTL_2 reference voltage.
