Address Inputs (A
Address Strobe Input. Used as an address qualifier. This signal should be asserted LOW to
access the part using an externally supplied address. Asserting this signal LOW also loads the
burst counter with the address present on the address pins.
Chip Enable Input. To select either the left or right port, both CE
their active states (CE
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 ADS or CNTRST are 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 (I/O
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.
