O/Z
Receive cell available status output signal from UTOPIA Slave.
0
indicates NO space is available to receive a cell from Master ATM Controller

indicates space is available to receive a cell from Master ATM Controller
When the UTOPIA peripheral is disabled (UTOPIA_EN [BEA11 pin] = 0), this pin is tied-off.

I
UTOPIA receive interface enable input signal. Asserted by the Master ATM Controller to indi-
cate to the UTOPIA Slave to sample the Receive Data Bus (URDATA[7:0]) and URSOC signal
in the next clock cycle or thereafter.
When the UTOPIA peripheral is disabled (UTOPIA_EN [BEA11 pin] = 0), this pin is tied-off.
URSOCY
W13
I
h
Receive Start-of-Cell signal. This signal is output by the Master ATM Controller to indicate to
the UTOPIA Slave that the first valid byte of the cell is available to sample on the 8-bit Receive
Data Bus (URDATA[7:0]).
When the UTOPIA peripheral is disabled (UTOPIA_EN [BEA11 pin] = 0), this pin is tied-off.

I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground
IPD = Internal pulldown, IPU = Internal pullup. (These IPD/IPU signal pins feature a 30-k IPD or IPU resistor. To pull up a signal to the opposite
supply rail, a 1-k
resistor should be used.)
§ These pins are multiplexed pins. For more details, see the Device Configurations section of this data sheet.
hExternal pulldowns required: If UTOPIA is selected (BEA11 = 1) and these pins are connected to other devices, then a 10-k resistor must be
used to externally pull down each of these pins. If these pins are “no connects”, then only UXCLK and URCLK need to be pulled down and other
pulldowns are not necessary.
External pullups required: If UTOPIA is selected (BEA11 = 1) and these pins are connected to other devices, then a 10-k resistor must be used
to externally pull up each of these pins. If these pins are “no connects”, then the pullups are not necessary.
ΨThe C6414 device does not support the UTOPIA peripheral; therefore, these standalone UTOPIA pins are Reserved (leave unconnected, do
not connect to power or ground) with the exception of UXCLK and URCLK which should be connected to a 10-k
pulldown resistor (see the
square [
h] footnote).
