1.  Supply voltage: 1.7 V to 3.8 V. The supply voltage of GR5515I0ND/GR5515I0NDA (when the external Flash ofGR5515I0NDA supplied by high voltage) shall equal the working voltage of external QSPI Flash

2.  I/O voltage: 1.8 V to 3.3 V (Typical) (for GR5515I0ND/GR5515I0NDA/GR5515IENDU/GR5513BENDU Flashusing high voltage, the VIO_LDO_OUT shall be connected to VBATL in schematic circuit.)
