PIN CONFIGURATION DESCRIPTION
PIN
NAME
INPUT FUNCTION
CLK
System Clock
Active on the positive going edge to sample all inputs.
Disables or enables device operation by masking or enabling all inputs except
CLK, CKE and DQMi
CS
Chip Select
CKE
Clock
Enable
Masks system clock to freeze operation from the next clock cycle.
CKE should be enabled at least one clock +t
SS
prior to new command.
Disable input buffers for power down in standby.

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 RAS low.
Enables row access & precharge.
CAS
Column Address Strobe
Latches column addresses on the positive going edge of the CLK with CAS low.
Enables column access.
WE
Write Enable
Enables write operation and Row precharge.
DQMi
Data Input/Output Mask
Makes data output Hi-Z, t
SHZ
after the clock and masks the output.
Blocks data input when DQM active.(Byte Masking)
