Function
The system clock inputs. All of the SDRAM inputs are sampled on the rising edge of their associated
clock.
Activates the SDRAM CLK signal when high and deactivates the CLK signal when low. By deactivating
the clocks, CKE low initiates the Power Down mode, or the Self Refresh mode.
Enables the associated 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-A12 defines the row address (RA0-RA12) when sampled at
the rising clock edge.
During a Read or Write command cycle, A0-A8 defines the column address (CA0-CA8) when sampled at
the rising clock edge. In addition to the column address, A10/AP is used to invoke autoprecharge opera-
tion at the end of the burst read or write cycle. If 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 control 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 precharge.
Data Input/Output pins.
Data strobe for input and output data.
This bidirectional pin is used to transfer data into or out of the SPD EEPROM. A resistor must be con-
nected 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 connected on the
system board from the SCL bus line to V
DD
to act as a pullup.
Power and ground for the SDRAM input buffers and core logic.
No Connection.
