–
Addresses: These inputs are registered and must meet
the set-up and hold times around the rising edge of CLK.
The burst counter generates internal addresses
associated with A0 and A1, during burst cycle and wait
cycle.
Byte Write Enables: A byte Write enable is LOW for a
Write cycle and HIGH for a Read cycle. BWa controls DQa.
BWb controls DQb. Data I/O are high impedance if either
of these inputs are LOW, conditioned by BWE being LOW.
Write Enable: This active LOW input gates byte Write
operations and must meet the set-up and hold times
around the rising edge of CLK.
Global Write: This active LOW input allows a full 18-bit
Write to occur independent of the BWE and WEn lines and
must meet the set-up and hold times around the rising
edge of CLK.
Clock: This signal registers the addresses, data, chip
enables, Write control and burst control inputs on its rising
edge. All synchronous inputs must meet set-up and hold
times around the clock’s rising edge.
Chip Enable: This active LOW input is used to enable the
device and to gate ADSP.
Data Inputs/Outputs: First Byte is DQa. Second Byte is
DQb. Third Byte is DQc. Fourth Byte is DQd. Input data
must meet set-up and hold times around the rising edge
of CLK.
IEEE 1149.1 Test Inputs: LVTTL-level inputs. Not
available for A package version.
IEEE 1149.1 Test Output: LVTTL-level output. Not
available for A package version.
Ground: GND.
Power Supply for the I/O circuitry
No Connect: These signals are not internally connected.
User can leave it floating or connect it to V
