CPU_PLL_AVDD
CORE_PLL_AVDD
1.7 1.8 1.9 V Analog supply for the internal PLL
SSCG_AVDD 1.7 1.8 1.9 V Analog supply for:
Internal Spread Spectrum Clock
Generator
VDD_GE_A
VDD_GE_B
3.15 3.3 3.45 V I/O voltage for:
RGMII(10/100 RGMII only)/
GMII/MII/MMII/SMI interfaces
1.7 1.8 1.9 V I/O voltage for:
RGMII/SMI interfaces
VDD_M 1.7 1.8 1.9 V I/O voltage for:
SDRAM interface
VDDO 3.15 3.3 3.45 V I/O voltage for:
MPP, TWSI, JTAG, SDIO, I
2
S, SPI,
TS, and TDM interfaces
VHV (during eFuse
Burning mode)
2.375 2.5 2.625 V I/O voltage for eFuse burning
NOTE: If the VHV voltage is higher
than VDD voltage (burning
mode), VDD must be
powered before VHV, to
prevent the fuse from being
accidentally burned.
VHV (during eFuse
Reading mode)
0.95 1.0 1.05 V I/O voltage for eFuse reading
NOTE: It is recommended that if
only a read operation is
required, VHV would be
connected to the device
VDD power.
