适用小家电、智能家居、智能玩具、工业控制、医疗监护等广泛的物联网领域。

1.2管脚定义下图为Air103管脚定义，所有GPIO如果芯片内部配置为上拉，上拉电阻典型值为40K，如果配置为下拉，下拉电阻典型值值为49K。

注：SPI0与SPI1是同一个SPI控制器，仅能选一种使用；PWM脚的命名数字分2位：XY，其中Y相同的PWM脚，只能选取一个，不能同时使用，例如PWM01与PWM11不能同时生效。

二、外围电路设计2.1复位电路复位电路建议设计为RC电路，上电自动复位，同时按键按下为低电平复位。

当电平值低于2.0v时，芯片处于复位状态。

复位时低电平需持续100us以上。

2.2时钟电路参考时钟选用40MHz频率，根据实际产品需求选用不同温度等级、稳定度、负载电容值的晶体。

晶体两端所接负载电容根据不同厂家晶体及频偏情况需要调整。

晶体摆放尽量靠近芯片，走线尽量短，并且远离干扰源，时钟周围多地孔隔离。

时钟下面各层禁止其它走线穿过，防止干扰时钟源。
