Address Inputs: Provide the row address for ACTIVE
commands, and the column address and auto precharge bit
(A10) for READ/WRITE commands, to select one location out
of the memory array in the respective device bank. A10
sampled during a PRECHARGE command determines
whether the PRECHARGE applies to one device bank (A10
LOW, device bank selected by BA0, BA1) or all device banks
(A10 HIGH). The address inputs also provide the op-code
during a MODE REGISTER SET command. BA0 and BA1 define
which mode register (mode register or extended mode
register) is loaded during the LOAD MODE REGISTER
command.
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.
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.
Data Write Mask: DM LOW allows WRITE operation. DM
HIGH blocks WRITE operation. DM lines do not affect READ
operation.
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.
SSTL_2 reference voltage.
DQ Power Supply: +2.5V ±0.2V.
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.
