to be programmed at any time. All devices are shipped in
the erased state from the factory.
Applying power to a blank part might result in a higher cur-
rent flow as the part initializes. This behavior is normal and
might persist for approximately 2 seconds, depending on
the power supply ramp.
If the device is programmed, the device inputs and outputs
take on their configured states for normal operation. The
JTAG pins are enabled to allow device erasure or bound-
ary-scan tests at any time.

assign input and output voltages to a bank with V
the voltage range of that input or output voltage. The V
(internal supply voltage) for a CoolRunner-II CPLD must be
maintained within 1.8V ±5% for correct speed operation and
proper in system programming.
Mixed Voltage, Power Sequencing, and
Hot Plugging
As mentioned in I/O Banking, CoolRunner-II CPLD parts
support mixed voltage I/O signals. It is important to assign
signals to an I/O bank with the appropriate I/O voltage. Driv-
ing a high voltage into a low voltage bank can result in neg-
ative current flow through the power supply pins. The power

I/Os are active. CoolRunner-II CPLDs can reside on boards
where the board is inserted into a “live” connector (hot
plugged) and the parts will be well-behaved as if powering
up in a standard way.
Development System Support
Xilinx CoolRunner-II CPLDs are supported by all configura-
tions of Xilinx standard release development software as
well as the freely available ISE WebPACK software avail-
able from www.xilinx.com. Third party development tools
include synthesis tools from Cadence, Exemplar, Mentor
Graphics, Synplicity, and Synopsys.
ATE Support
Third party ATE development support is available for both
programming and board/chip level testing. Vendors provid-
ing this support include Agilent, GenRad, and Teradyne.
Other third party providers are expected to deliver solutions
in the future.
