Description

Analog 1.8 V core power supply: This is the power supply

voltage for internal circuitry. This should be nominally the

same voltage as VDD(1V8) but should be isolated to minimize

noise and error.

3.3 V pad power supply: This is the power supply voltage for

the I/O ports.

Analog 3.3 V pad power supply: This should be nominally

the same voltage as VDD(3V3) but should be isolated to

minimize noise and error.

[1] 5 V tolerant pad providing digital I/O functions with TTL levels and hysteresis and 10 ns slew rate control.

[2] 5 V tolerant pad providing digital I/O functions with TTL levels and hysteresis and 10 ns slew rate control. If conï¬gured for an input

function, this pad utilizes built-in glitch ï¬lter that blocks pulses shorter than 3 ns.

[3] Open drain 5 V tolerant digital I/O I2C-bus 400 kHz speciï¬cation compatible pad. It requires external pull-up to provide an output

functionality.

[4] 5 V tolerant pad providing digital I/O (with TTL levels and hysteresis and 10 ns slew rate control) and analog input function. If conï¬gured

for a digital input function, this pad utilizes built-in glitch ï¬lter that blocks pulses shorter than 3 ns. When conï¬gured as an ADC input,

digital section of the pad is disabled.

[5] 5 V tolerant pad with built-in pull-up resistor providing digital I/O functions with TTL levels and hysteresis and 10 ns slew rate control.

The pull-up resistorâs value ranges from 60 kâ¦ to 300 kâ¦.

[6] 5 V tolerant pad providing digital input (with TTL levels and hysteresis) function only.

[7] Pad provides special analog functionality.
