Notes:
1. All parameters representing voltages are measured with respect to GND unless otherwise specified.
2. The following 1.5 V supplies should be connected together while following proper noise filtering practices: VCC,
VCC15A, and VCC15ADCx.
3. The Programming temperature range supported is T
ambient
= 0°C to 85°C.
4. VPP
can be left floating during operation (not programming mode).
5. The ranges given here are for power supplies only. The recommended input voltage ranges specific to each I/O
standard are given in Table 2-19 on page 2-23. VCCxxxxIOBx should be at the same voltage within a given I/O bank.
6. The following 3.3 V supplies should be connected together while following proper noise filtering practices: VCC33A,
VCC33ADCx, VCC33AP, VCC33SDDx, VCCMAINXTAL, and VCCLPXTAL.
