PIN FUNCTION DESCRIPTION
Pin
Name
Input Function
CLK
System clock
Active on the positive going edge to sample all inputs.
CS
Chip select
Disables or enables device operation by masking or enabling all inputs except
CLK, CKE and L(U)DQM
CKE
Clock enable
Masks system clock to freeze operation from the next clock cycle.
CKE should be enabled at least one cycle prior to new command.
Disable input buffers for power down in standby.

BA
Bank select address
Selects bank to be activated during row address latch time.
Selects bank for read/write during column address latch time.
RAS
Row address strobe
Latches row addresses on the positive going edge of the CLK with
Enables row access & precharge.
RAS low.
CAS
Column address strobe
Latches column addresses on the positive going edge of the CLK with
Enables column access.
CAS low.
WE
Write enable
Enables write operation and row precharge.
Latches data in starting from CAS, WE active.
L(U)DQM
Data input/output mask
Makes data output Hi-Z, t
SHZ
after the clock and masks the output.
Blocks data input when L(U)DQM active.

/V
SSQ
Data output power/ground
Isolated power supply and ground for the output buffers to provide improved noise
immunity.
N.C/RFU
No connection
/reserved for future use
This pin is recommended to be left No Connection on the device.
