Pin Functions
CK, /CK (input pin)
The CK and the /CK are the master clock inputs. All inputs except DMs, DQSs and DQs are referred to the cross
point of the CK rising edge and the VREF level. When a read operation, DQSs and DQs are referred to the cross
point of the CK and the /CK. When a write operation, DQs are referred to the cross point of the DQS and the VREF
level. DQSs for write operation are referred to the cross point of the CK and the /CK.
/CS (input pin)
When /CS is low, commands and data can be input. When /CS is high, all inputs are ignored. However, internal
operations (bank active, burst operations, etc.) are held.
/RAS, /CAS, and /WE (input pins)
These pins define operating commands (read, write, etc.) depending on the combinations of their voltage levels.
See “Command operation”.
A0 to A13 (input pins)
Row address (AX0 to AX13) is determined by the A0 to the A13 level at the cross point of the CK rising edge and the
VREF level in a bank active command cycle. Column address (AY0 to AY9, AY11) is loaded via the A0 to the A9
and A11 at the cross point of the CK rising edge and the VREF level in a read or a write command cycle. This
column address becomes the starting address of a burst operation.
A10 (AP) (input pin)
A10 defines the precharge mode when a precharge command, a read command or a write command is issued. If
A10 = high when a precharge command is issued, all banks are precharged. If A10 = low when a precharge
command is issued, only the bank that is selected by BA1, BA0 is precharged. If A10 = high when read or write
command, auto-precharge function is enabled. While A10 = low, auto-precharge function is disabled.
BA0, BA1, BA2 (input pin)
BA0, BA1 and BA2 are bank select signals (BA). The memory array is divided into 8 banks
:
bank 0 to bank 7. (See
Bank Select Signal Table)
