Function
Data Strobe Bus 7:0
Data Mask Bus 7:0
The data write masks, associated with one data byte. In
Write mode, DM operates as a byte mask by allowing input
data to be written if it is LOW but blocks the write operation
if it is HIGH. In Read mode, DM lines have no effect.
Serial Bus Clock
This signal is used to clock data into and out of the SPD
EEPROM and Thermal sensor.
Serial Bus Data
This is a bidirectional pin use to transfer data into and out of
the SPD EEPROM and Thermal sensor. A resistor must be
connected from SDA to
a pull-up.
Serial Address Select Bus 2:0
Address pins used to select the SPD and Thermal sensor
base address.
EVENT
The optional EVENT pin is reserved for use to flag critical
module temperature and is used in conjunction with
Thermal Sensor.
Not Connected
Not connected on modules without temperature sensors.
I/O Reference Voltage
Reference voltage for the SSTL-18 inputs.
EEPROM Power Supply
Power supplies for Serial Presence Detect, Thermal Sensor
and ground for the module.
Power Supply
Power supplies for core, I/O and ground for the module.
Ground Plane
Power supplies for core, I/O, Serial Presence Detect,
Thermal Sensor and ground for the module.
