Power Sequencing
The maximum voltage that you can you drive into an I/O with the device powered or
unpowered, is limited to the Vi/Vin parameter in the family data sheet.

•
In terms of current, the absolute maximum current that should be applied to an
unpowered part is 100mA to the whole part.
Before the device is configured and for unprogrammed devices, the status of the I/Os are
disabled and terminated with a weak pull-up.
The following list indicates whether or not devices are hot-swappable:

XC9500 has clamp diodes to V
CoolRunner-II devices do not.
Some of the CPLD families have multiple voltage rails. V

supplies power to JTAG pins on the CoolRunner-II. In previous families the JTAG pins
were powered by V
CoolRunner-II CPLDs have three separate voltage rails: V
XC9500, XC9500XL, and XC9500XV have two separate voltage rails; V
CoolRunner-II devices are guaranteed to work under all power sequences. However, the

comes alive before the I/Os, or if the I/Os are to come alive before the CPLD logic.

XC9500: You can drive into an unpowered I/O, provided Vin does not exceed the Vin
limits of the CPLD.
XC9500XL: You can drive into an unpowered I/O, provided Vin does not exceed
V
XC9500XV: You can drive into an unpowered I/O, provided Vin does not exceed the
Vin limits of the CPLD.
CoolRunner XPLA3: You can drive into an unpowered I/O, provided Vin does not
exceed V
CoolRunner-II: You can drive into an unpowered I/O, provided Vin does not exceed
the Vin limits of the CPLD.
CoolRunner-II: Yes
CoolRunner XPLA3: Yes
XC9500XL: Yes
XC9500XV: Yes
XC9500: No
