Supported I/O Standards
The XC95288XV CPLD features both LVCMOS and LVTTL
I/O implementations. See Table 1 for I/O standard voltages.
The LVTTL I/O standard is a general purpose EIA/JEDEC
standard for 3.3V applications that use an LVTTL input
buffer and Push-Pull output buffer. The LVCMOS2 standard
is used in 2.5V applications.
XC9500XV CPLDs are also 1.8V I/O compatible. The
X25TO18 setting is provided for generating 1.8V compatible
outputs from a CPLD normally operating in a 2.5V environ-
ment. The ISE software automatically groups outputs with
matching IOSTANDARD settings into the same V
CCIO
bank
when no location constraints are specified. The default I/O
Standard for pads without IOSTANDARD attributes is
LVTTL for XC9500XV devices.

Notes:
1. Maximum DC undershoot below GND must be limited to either 0.5V or 10 mA, whichever is easier to achieve. During transitions, the
device pins may undershoot to –2.0V or overshoot to +3.6V, provided this over- or undershoot lasts less than 10 ns and with the
forcing current being limited to 200 mA.
2. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress
ratings only, and functional operation of the device at these or any other conditions beyond those listed under Operating Conditions
is not implied. Exposure to Absolute Maximum Ratings conditions for extended periods of time may affect device reliability.
