Signal Pin Description
Pin
Type
Signal
Polarity
Function
CLK
Input
Pulse
Positive
Edge
The system clock input. All inputs except DQs and DMs are sampled on the rising edge
of CLK.
CKE
Input
Level
Active High Activates the CLK signal when high and deactivates the CLK signal when low, thereby
initiates either the Power Down mode, Suspend mode, or the Self Refresh mode.
CS
Input
Pulse
Active Low CS enables the command decoder when low and disables the command decoder when
high. When the command decoder is disabled, new commands are ignored but previous
operations continue.
RAS,CAS
WE
Input
Pulse
Active Low When sampled at the positive rising edge of the clock, CAS,RAS,and WE define the
command to be executed by the SDRAM.
DQS
Input/
Output
Pulse
Active High Active on both edges for data input and output.

Edge aligned to output data
A0 - A11
Input
Level
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-An defines the column address (CA0-CAn)
when sampled at the rising clock edge.CAn depends from the SDRAM organization:
8M x 8 SDRAM CAn = CA8 (Page Length = 512 bits)
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 is high, autoprecharge is selected and
BA0, BA1 defines the bank to be precharged. If A10 is low, autoprecharge is disabled.
During a Precharge command cycle, A10(=AP) is used in conjunction with BA0 and BA1
to control which bank(s) to precharge. If A10 is high, all four banks will be precharged
simultaneously regardless of state of BA0 and BA1.
BA0,
BA1
Input
Level
Selects which bank is to be active.
DQx
Input/
Output
Level
Data Input/Output pins operate in the same manner as on conventional DRAMs.
DM
Input
Pulse
Active High In Write mode, DM has a latency of zero and operates as a word mask by allowing input
data to be written if it is low but blocks the write operation if is high.
VDD, VSS
Supply
Power and ground for the input buffers and the core logic.
VDDQ
VSSQ
Supply
——
Isolated power supply and ground for the output buffers to provide improved noise
immunity.
VREF
Input
Level
SSTL Reference Voltage for Inputs
