Digital I/Os

SD2 provides firmware controlled pull-up or pull-down resistors

internally on all digital I/O pins. The pins can be pulled high

through an internal 50-k

 resistor or can be pulled low through

an internal 10-k

 resistor to prevent the pins from floating. The

I/O pins may have the following states:

■ Tristated (High-Z)

■ Weak pull-up (through internal 50 k)

■ Pull down (through 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 based on each interface.

EMI

SD2 meets EMI requirements outlined by FCC 15B (USA) and

EN55022 (Europe) for consumer electronics. SD2 can tolerate

reasonable EMI, conducted by aggressor, outlined by these

specifications and continue to function as expected.

System Level ESD

SD2 has built-in ESD protection on the D+, D–, 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.

The S0/S1_INS have up to ±2.2 KV HBM internal ESD

protection.
