Description
A0R–A15R
ADSR
Address Inputs (A0–A14 for 32K, A0–A13 for 16K devices).
Address Strobe Input. Used as an address qualifier. This signal must 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.
CE0R,CE1R
CLKR
CNTENR
Chip Enable Input. To select either the left or right port, both CE0 AND CE1 must be asserted to their
active states (CE0 VIL and CE1 VIH).
Clock Signal. This input can be free running or strobed. Maximum clock input rate is fMAX.
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.
CNTRSTR
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.
I/O0R–I/O17R
LBR
Data Bus Input/Output (I/O0–I/O15 for × 16 devices).
Lower Byte Select Input. Asserting this signal LOW enables read and write operations to the lower
byte. (I/O0–I/O8 for × 18, I/O0–I/O7 for × 16) of the memory array. For read operations both the LB and
OE signals must be asserted to drive output data on the lower byte of the data pins.
UBR
OER
Upper Byte Select Input. Same function as LB, but to the upper byte (I/O8/9L–I/O15/17L).
Output Enable Input. This signal must be asserted LOW to enable the I/O data pins during read
operations.
R/WR
Read/Write Enable Input. This signal is asserted LOW to write to the dual port memory array. For
read operations, assert this pin HIGH.
FT/PIPER
Flow Through/Pipelined Select Input. For flow through mode operation, assert this pin LOW. For
pipelined mode operation, assert this pin HIGH.
Ground Input.
No Connect.
Power Input.
