NOTE:
1. X means “Don’t Care.” H means logic HIGH. L means logic LOW.
2. For
WRITE
, L means one or more byte write enable signals (
BWa-d
) and
BWE
are LOW or
GW
is LOW.
WRITE
= H for all
BWx
,
BWE
,
GW
HIGH.
3.
BWa
enables WRITEs to DQa’s and DQPa.
BWb
enables WRITEs to DQb’s and DQPb.
BWc
enables WRITEs to DQc’s and
DQPc.
BWd
enables WRITEs to DQd’s and DQPd. DQPa and DQPb are available on the x18 version. DQPa-DQPd are
available on the x36 version.
4. All inputs except
OE
and ZZ must meet setup and hold times around the rising edge (LOW to HIGH) of CLK.
5. Wait states are inserted by suspending burst.
6. For a WRITE operation following a READ operation,
OE
must be HIGH before the input data setup time and held HIGH during the
input data hold time.
7. This device contains circuitry that will ensure the outputs will be in High-Z during power-up.
8.
ADSP
LOW always initiates an internal READ at the L-H edge of CLK. A WRITE is performed by setting one or more byte write
enable signals and
BWE
LOW or
GW
LOW for the subsequent L-H edge of CLK. See WRITE timing diagram for clarification.
