Notes:
1.
Descriptions of the symbols used in this table are as follows:
VCCO – the supply voltage for output drivers
VREF – the reference voltage for setting the input switching threshold
VIL – the input voltage that indicates a Low logic level
VIH – the input voltage that indicates a High logic level
2.
The VCCO rails supply only output drivers, not input circuits.
3.
For device operation, the maximum signal voltage (VIH max) may be as high as VIN max. See Table 72 in DS312.
4.
There is approximately 100 mV of hysteresis on inputs using LVCMOS33 and LVCMOS25 I/O standards.
5.
All Dedicated pins (PROG_B, DONE, TCK, TDI, TDO, and TMS) use the LVCMOS25 standard and draw power from the VCCAUX rail (2.5V).
The Dual-Purpose configuration pins use the LVCMOS standard before the User mode. When using these pins as part of a standard 2.5V
configuration interface, apply 2.5V to the VCCO lines of Banks 0, 1, and 2 at power-on as well as throughout configuration.
