RTC

83

RTC_IO

OD

RTC 唤醒

32K 时钟输出

OD 输出，外部需上拉电阻，上拉电压不能超过 5 V。

84

RTC_VCOIN

POWER

-

若不考虑掉电保持可悬空，内部有二极管从 3.3 V 取电，外挂供电需接 RC 延迟上电 (10 KΩ/ 0.1 uF)。

85

RTC_XO

OUTPUT

-

接 32.768 KHz 无源晶振，若不使用 RTC 功能可悬空。

86

RTC_XI

INPUT

-

接 32.768 KHz 无源晶振，若不使用 RTC 功能可悬空。

SYS

67

RESETN

INPUT

系统复位

内置约 30 ㏀ 上拉电阻和去抖滤波，不使用可直接悬空，若外挂电容建议不超过 4.7 uF。

81

PLL_XO

OUTPUT

-

接 24 MHz 无源晶振。

82

PLL_XI

INPUT

-

接 24 MHz 无源晶振。
