The VCCINT pins must always be connected to a 2.5-V power supply.
With a 2.5-V V
V, and 5.0-V inputs. The VCCIO pins can be connected to either a 2.5-V or
3.3-V power supply, depending on the output requirements. When the
VCCIO pins are connected to a 2.5-V power supply, the output levels are
compatible with 2.5-V systems. When the VCCIO pins are connected to a
3.3-V power supply, the output high is at 3.3 V and is therefore compatible
with 3.3-V or 5.0-V systems. Devices operating with V
than 3.0 V achieve a faster timing delay of t

Open-drain output pins on ACEX 1K devices (with a pull-up resistor to
the 5.0-V supply) can drive 5.0-V CMOS input pins that require a higher
V
When the pin is inactive, the resistor will pull up the trace to 5.0 V, thereby
meeting the CMOS V
low or tri-state; it will never drive high. The rise time is dependent on the
value of the pull-up resistor and load impedance. The I
specification should be considered when selecting a pull-up resistor.
Because ACEX 1K devices can be used in a mixed-voltage environment,
they have been designed specifically to tolerate any possible power-up
sequence. The V

Signals can be driven into ACEX 1K devices before and during power up
without damaging the device. Additionally, ACEX 1K devices do not
drive out during power up. Once operating conditions are reached,
ACEX 1K devices operate as specified by the user.
