Product data sheet
5 V tolerant pad (no built-in pull-up resistor) providing digital I/O (with TTL levels and hysteresis and 10 ns slew rate control) and analog
input function. If configured for an 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 (no built-in pull-up resistor) providing digital I/O (with TTL levels and hysteresis and 10 ns slew rate control) and analog
output function. When configured as the DAC output, 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 typically ranges from 60 k to 300 k .
Pad is designed in accordance with the Universal Serial Bus (USB) specification, revision 2.0 (Full-speed and Low-speed mode only).
5 V tolerant pad providing digital input (with TTL levels and hysteresis) function only.
Pad provides special analog functionality.
