Address Inputs (A
Address Strobe Input. Used as an address qualifier. This signal should be asserted LOW to
assert the part using the externally supplied address on Address Pins. To load this address into
the Burst Address Counter both ADS and CNTEN have to be LOW. ADS is disabled if CNTRST
is asserted LOW
Chip Enable Input.
Clock Signal. This input can be free-running or strobed. Maximum clock input rate is f
Counter Enable Input. Asserting this signal LOW increments the burst address counter of its
respective port on each rising edge of CLK. CNTEN is disabled if CNTRST is asserted LOW.
Counter Reset Input. Asserting this signal LOW resets the burst address counter of its
respective port to zero. CNTRST is not disabled by asserting ADS or CNTEN.
Data Bus Input/Output.
Output Enable Input. This signal must be asserted LOW to enable the I/O data pins during read
operations.
Read/Write Enable Input. This signal is asserted LOW to write to the dual port memory array.
For read operations, assert this pin HIGH.
Flow-Through/Pipelined Select Input. For flow-through mode operation, assert this pin LOW.
For pipelined mode operation, assert this pin HIGH.
Byte Select Inputs. Asserting these signals enable read and write operations to the corre-
sponding bytes of the memory array.
Select Pins for Bus Matching. See Bus Matching for details.
Big Endian Pin. See Bus Matching for details.
