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 V
DD(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.

5 V tolerant pad providing digital I/O functions with TTL levels and hysteresis and 10 ns slew rate control.
5 V tolerant pad providing digital I/O functions with TTL levels and hysteresis and 10 ns slew rate control. If configured for an input
function, this pad utilizes built-in glitch filter that blocks pulses shorter than 3 ns.
Open drain 5 V tolerant digital I/O I

C-bus 400 kHz specification compatible pad. It requires external pull-up to provide an output
functionality.
5 V tolerant pad providing digital I/O (with TTL levels and hysteresis and 10 ns slew rate control) and analog input function. If configured
for a digital input function, this pad utilizes built-in glitch filter that blocks pulses shorter than 3 ns. When configured as an ADC input,
digital section of the pad is disabled.
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 resistor’s value ranges from 60 kΩ to 300 kΩ.
5 V tolerant pad providing digital input (with TTL levels and hysteresis) function only.
Pad provides special analog functionality.
