TCC76x Description
VDDIO
2.7 ~ 3.3 V
1.8 ~ 3.3 V
Wide range I/O.
VDD_NOR
VDD_OSC
2.7 ~ 3.3 V
X
2.7 ~ 3.3 V or
1.8 V
TBD ~1.8 V
In the TCC76x, there are 2 versions of voltage condition.
One is same as that of the TCC72x and the other is for low-power consumption so it has
lower voltage condition than the former one.
In the TCC72x this pin is contained in VDDI group.
In the TCC76x, it is dedicated for oscillator power for XIN and XTIN pins, so in case of
lowering VDDI than 1.8V, it should be maintained at 1.8V. The voltage level of XIN and
XTIN pins must not exceed VDD_OSC level.

2.7 ~ 3.3 V or
1.8 V
Lower than the TCC72x The lower limit is not yet confirmed.
In the TCC72x this pin is represented as VDDI_aip.
Its function is same except of voltage condition.
In the TCC76x, there are 2 versions of voltage condition.
One is same as that of the TCC72x and the other is for low-power consumption so it has
lower voltage condition than the former one.
VDDC_WF
1.8 ~ 3.3 V TBD ~ 3.3 V Same as the TCC72x but the lower limit below 1.8V will be determined later.
VDDA_PLL
2.5 V
TBD ~ 1.8 V Lower than the TCC72x.
VDDA_ADC
2.5 V
TBD ~ 3.3 V It has higher condition than the TCC72x.
Note: Lower limits for the voltage range under 1.8V are to be determined.
