Address 0 - 7 (5V Tolerant Input): These lines provide the A0 to A7
address lines to the internal memories.
Data Strobe (5V Tolerant Input): This active low input works in
conjunction with CS to enable the read and write operations.
Read/Write (5V Tolerant Input): This input controls the direction of
the data bus lines (D0-D15) during a microprocessor access.
Chip Select (5V Tolerant Input): Active low input used by a
microprocessor to activate the microprocessor port.
Data Bus 0 -15 (5V Tolerant I/O): These pins form the 16-bit data bus
of the microprocessor port.
Data Transfer Acknowledgment (5V Tolerant Three-state Output):
This active low output indicates that a data bus transfer is complete. A
pull-up resistor is required to hold a HIGH level when the pin is tri-
stated.
Serial Input Streams 0 to 3 (5V Tolerant Inputs): In 2Mb/s or
Subrate Switching mode, these inputs accept data rates of 2.048 Mb/s
with 32 channels per stream. In 8Mb/s mode, these inputs accept data
rates of 8.192 Mb/s with 128 channels per stream.
Serial Input Streams 4 to 11 (5V Tolerant Inputs): In 2Mb/s or Sub-
rate Switching mode, these inputs accept data rates of 2.048Mb/s
with 32 channels per stream.
Serial Input Streams 12 (5V Tolerant Input): In 2Mb/s mode, this
input accepts data rate of 2.048Mb/s with 32 channels per stream
respectively. In Sub-rate Switching mode, this pin accepts 2.048Mb/s
with 128 channels per stream for Sub-rate switching application.
these inputs accept a data rate of 2.048Mb/s with 32 channels per
stream.
Output Drive Enable (5V Tolerant Input): This is the output enable
control for the STo0 to STo15 serial outputs and STio0 to STio31 serial
bidirectional outputs.
Serial Output Streams 0 to 3 (5V Tolerant Three-state Outputs): In
2Mb/s or Sub-rate Switching mode, these outputs have data rates of
2.048 Mb/s with 32 channels per stream respectively. In 8Mb/s mode,
these outputs have data rates of 8.192 Mb/s with 128 channels per
stream
Serial Output Streams 4 to 11 (5V Tolerant Three-state Outputs):
In 2Mb/s or Sub-rate Switching mode, these outputs have data rates of
2.048Mb/s with 32 channels per stream
