Digital I/Os

SX3 has internal firmware-controlled pull-up and pull-down

resistors on all digital I/O pins. An internal 50-k

 resistor pulls

the pins high, while an internal 10-k

 resistor pulls the pins low

to prevent them from floating. The I/O pins may have the

following states:

■ Tristated (High-Z)

■ Weak pull-up (via internal 50 k)

■ Pull-down (via internal 10 k)

■ Hold (I/O hold its value) when in low-power modes

All unused I/Os should be pulled high by using the internal

pull-up resistors. All unused outputs should be left floating. All

I/Os can be driven at full-strength, three-quarter strength,

half-strength, or quarter-strength. These drive strengths are

configured separately for each interface.

GPIOs

SX3 supports seven GPIOs. They can be configured to one of

the pre-defined Input or Output function using the SX3

Configuration utility. All general configurable interface pins and

GPIO pins support an external load of up to 16 pF for every pin.

EMI

SX3 meets EMI requirements outlined by FCC 15B (USA) and

EN55022 (Europe) for consumer electronics. SX3 can tolerate

EMI, conducted by the aggressor, outlined by these specifica-

tions and continue to function as expected.

System-level ESD

SX3 has built-in electrostatic discharge (ESD) protection on the

D+, D–, and GND pins on the USB interface. The ESD protection

levels provided on these ports are:

■ ±2.2-kV human body model (HBM) based on JESD22-A114

Specification.

■ ±6-kV contact discharge and ±8-kV air gap discharge based

on IEC61000-4-2 level 3A.

■ ± 8-kV Contact Discharge and ±15-kV Air Gap Discharge based

on IEC61000-4-2 level 4C.

This protection ensures the device continues to function after

ESD events up to the levels stated in this section.

The SSRX+, SSRX–, SSTX+, and SSTX– pins only have up to

±2.2-kV HBM internal ESD protection.
