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.

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 k to 300 k .
5 V tolerant pad providing digital input (with TTL levels and hysteresis) function only.
Pad provides special analog functionality.

Description
PLL analog ground: 0 V reference. This should nominally be the same
voltage as V
1.8 V core power supply: This is the power supply voltage for internal
circuitry.
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
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 V
