Symbol
Type
Description
DQS[8:0]
DQS#[8:0]
I/O
Data strobe: DQS and DQS# are differential data strobes. Output with read data. Edge-
aligned with read data. Input with write data. Center-aligned with write data.
SDA
I/O
Serial data: SDA is a bidirectional pin used to transfer addresses and data into and out of
the temperature sensor/SPD EEPROM on the module on the I2C bus.
Err_Out#
Output
(open drain)
Parity error output: Parity error found on the command and address bus.
EVENT#
Output
(open drain)
Temperature event: The EVENT# pin is asserted by the temperature sensor when critical
temperature thresholds have been exceeded.

VREFCA
Supply
Reference voltage: Control, command, and address (VDD/2).
VREFDQ
Supply
Reference voltage: DQ, DM (VDD/2).
VSS
Supply
Ground.
VTT
Supply
Termination voltage: Used for control, command, and address (VDD/2).
NC
No connect: These pins are not connected on the module.
NF
No function: Connected within the module, but provides no functionality.
