Serial Clock for Presence-Detect: SCL is used to
synchronize the presence-detect data transfer to and
from the module.
Presence-Detect Address Inputs: These pins are used
to configure the presence-detect device.
Serial Presence-Detect Data: SDA is a bidirectional pin
used to transfer addresses and data into and out of
the presence-detect portion of the module.
Asynchronously forces all register outputs LOW when
RESET# is LOW. This signal can be used during power-
up to ensure CKE are LOW and DDR SDRAM DQs are
High-Z.
Data I/Os: Check bits. ECC, 1-bit error detection and
correction.
Data Strobe: Output with READ data, input with WRITE
data. DQS is edge-aligned with READ data, centered in
WRITE data. Used to capture data.
Data I/Os: Data bus.
DQ Power Supply: +2.5V +0.2V.
Ground.
Serial EEPROM positive power supply–2.3V to 3.6V.
No Connect: These pins should be left unconnected.
Do Not Use: These pins are not connected on this
module but are assigned pins on other modules in
this product family.
