Description
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.
Bank address: BA0 and BA1 define the device bank to which an ACTIVE,
READ, WRITE, or PRECHARGE command is being applied.
Clock: CK and CK# are differential clock inputs. All address and control input
signals are sampled on the crossing of the positive edge of CK and the
negative edge of CK#. Output data (DQ and DQS) is referenced to the
crossings of CK and CK#.
Clock enable: CKE (registered HIGH) activates and CKE (registered LOW)
deactivates the internal clock, input buffers, and output drivers.
Command inputs: RAS#, CAS#, and WE# (along with S#) define the
command being entered.
Reset: Asynchronously forces all registered outputs LOW when RESET# is
LOW. This signal can be used during power-up to ensure that CKE is LOW and
DQ are High-Z.
Chip selects: S# enables (registered LOW) and disables (registered HIGH) the
command decoder.
Presence-detect address inputs: These pins are used to configure the
presence-detect device.
Serial clock for presence-detect: SCL is used to synchronize the presence-
detect data transfer to and from the module.
Check bits.
Data input/output: Data bus.
Data strobe: Output with read data, input with write data. DQS is edge-
aligned with read data, center-aligned with write data. Used to capture data.
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.
Power supply: +2.5V ±0.2V (-40B: +2.6V ±0.1V).
Serial EEPROM positive power supply: +2.3V to +3.6V.
SSTL_2 reference voltage (V
Ground.
No connect: These pins are not connected on the module.
