Polarity
Crossing Point
Function
The system clock inputs. All address and command lines are sampled on the cross point of
the rising edge of CK and falling edge of CK#. A Delay Locked Loop (DLL) circuit is driven
from the clock inputs and output timing for read operations is synchronized to the input
clock.
Activates the SDRAM CK signal when high and deactivates the CK signal when low. By
deactivating the clocks, CKE low initiates the Power Down mode, or the Self Refresh
mode.
Enables the associated DDR SDRAM command decoder when low and disables decoder
when high. When decoder is disabled, new commands are ignored but previous operations
continue.
When sampled at the positive rising edge of the clock, CAS#, RAS#, and WE# define the
operations to be executed by the SDRAM.
Selects which of the four internal SDRAM banks is activated.
During a Bank Activate command cycle, A0-A11 defines the row address (RA0-RA11)
when sampled at the rising clock edge.
During a Read or Write command cycle, A0-A9 defines the column address (CA0-CA9)
when sampled at the rising clock edge. In addition to the column address, A10/AP is used
to invoke autoprecharge operation at the end of the burst read or write cycle. If A10/AP is
high, autoprecharge is selected and BA0, BA1 defines the bank to be precharged. If AP is
low, autoprecharge is disabled.
During a Precharge command cycle, A10/AP is used in conjunction with BA0, BA1 to con-
trol which bank(s) to precharge. If AP is high, all banks will be precharged regardless of the
state of BA0 or BA1. If AP is low, BA0 and BA1 are used to define which bank to pre-
charge.
Data Bit Input/Output pins.
Masks write data when high, issued concurrently with input data. Both DM and DQ have a
write latency of one clock once the write command is registered into the SDRAM.
Data strobe for input and output data.
These signals are tied on the system to either V
SS
or V
DD
to configure the serial SPD.
This bidirectional pin is used to transfer data into or out of the SPD EEPROM. A resistor
must be connected on the system board from the SDA bus line to V
DD
to act as a pullup.
This signal is used to clock data into and out of the SPD EEPROM. A resistor may be con-
nected on the system board from the SCL bus line to V
DD
to act as a pullup.
Power and ground for the DDR SDRAM input buffers and core logic.
Reference voltage for SSTL2 inputs.
Isolated power supply for the DDR SDRAM output buffers to provide improved noise
immunity.
Serial EEPROM positive power supply (wired to a separate power pin at the connector
which supports both 2.3 Volt and 3.3 Volt operation).
