Function
Serial Bus Data
This is a bidirectional pin used to transfer data into or
out of the SPD EEPROM. A resistor must be
connected from SDA to
act as a pull-up.
Address pins used to select the Serial Presence
Detect base address.
I/O Reference Voltage
Reference voltage for the SSTL-18 inputs.
EEPROM Power Supply
Power supplies for core, I/O, Serial Presence Detect,
and ground for the module.
Power Supply
Power supplies for core, I/O, Serial Presence Detect,
and ground for the module.
Ground Plane
Power supplies for core, I/O, Serial Presence Detect,
and ground for the module.
On-Die Termination Control 1:0
On-Die Termination Control 1
Asserts on-die termination for DQ, DM, DQS, and
DQS signals if enabled via the DDR2 SDRAM mode
register.
