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-h) 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. BWe enables WRITEs to DQe’s and DQPe. BWf enables WRITEs to DQf’s
and DQPf.
BWg enables WRITEs to DQg’s and DQPg. BWh enables WRITEs to DQh’s and DQPh. DQPa-DQPh are avail-
able on the x72 version. 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.
