Power-Up Sequence for Silicon Revision 2
Silicon revision 2.0 offers two options for power-up sequencing. Option 1 is backwards compatible with
silicon revision 1.2 and earlier versions of the IC. It should be noted that using option 1 on silicon Rev. 2.0
introduces a slight increase in current drain on IOQVDD when IOQVDD is raised before NVCC21. The
expected resulting increase is in the range of 3 mA to 5 mA, which does not pose a risk to the IC.
Option 2 is an alternative power-up sequence that allows the powering up of NVCC2, NVCC21, NVCC22
with IOQVDD, NVCC1, and NVCC3-10 without producing a current drain increase on IOQVDD.
These two power-up options on the 2.0 silicon allow the user to select the optimum power-up sequence for
their application.

Notes:
1
The board design must guarantee that supplies reach 90% level before transition
to the next state, using Power Management IC or other means.
2
The NVCC1 supply must not precede IOQVDD by more than 0.2 V until IOQVDD
has reached 1.5 V. If IOQVDD is powered up first, there are no restrictions.
3
It is allowable for FVCC, MVCC, SVCC, and UVCC to be up after FUSE_VDD.
