Electrical Characteristics

4.6.1

XTALI and RTC_XTALI (Clock Inputs) DC Parameters

Table 22 shows the DC parameters for the clock inputs.

NOTE

The Vil and Vih specifications only apply when an external clock source is

used. If a crystal is used, Vil and Vih do not apply.

4.6.2

General Purpose I/O (GPIO) DC Parameters

Table 23 shows DC parameters for GPIO pads. The parameters in Table 23 are guaranteed per the

operating ranges in Table 8, unless otherwise noted.

XTALI input leakage current at startup

IXTALI_STARTUP

Power-on startup for

0.15msec with a driven

24 MHz clock at 1.1 V.2

2 This current draw is present even if an external clock source directly drives XTALI. The 24 MHz oscillator cell is powered from

NVCC_PLL_OUT.
