DESCRIPTION
CLK
INPUT
Clock : The system clock input. All other inputs are registered to the SDRAM on the
rising edge of CLK
CKE
INPUT
Clock Enable : Controls internal clock signal and when deactivated, the SDRAM will
be one of the states among power down, suspend or self refresh
CS
INPUT
Chip Select : Enables or disables all inputs except CLK, CKE, DQM0~DQM3
BA0, BA1
INPUT
Bank Address : Selects bank to be activated during RAS activity
Selects bank to be read/written during CAS activity
A0 ~ A13
INPUT
For 2KBytes Page Size, Row Address : A0~A13 / Column Address : A0~A8
For 4KBytes Page Size, Row Address : A0~A12 / Column Address : A0~A9
Auto-precharge flag : A10
RAS, CAS, WE
INPUT
Command Inputs : RAS, CAS and WE define the operation
Refer function truth table for details
DQM0 ~ DQM3
INPUT
Data Mask:Controls output buffers in read mode and masks input data in write
mode
DQ0 ~ DQ31
I/O
Data Input/Output:Multiplexed data input/output pin
VDD/VSS
SUPPLY
Power supply for internal circuits
VDDQ/VSSQ
SUPPLY
Power supply for output buffers
NC
