DA1469x的建议电压

嗨，

我正在寻找一些关于确定DA1469x系列中组件的电源电压的反馈。我知道有最大和最小阈值，但我不确定如何确定我的具体应用程序的最大和最小截止值。为了在更高的层次上提供一些额外的上下文，我的预期应用程序的MCU将使用锂离子电池，它将为显示器、IR接近传感器和MCU的存储器组件供电。我的想法是，我需要先完成我的硬件外设，但我想知道是否有其他方法来确定适当的电源要求。

如果您能帮助我，非常感谢您的回复。

谢谢。

Hi,
Can the DA14580 chip operate using a Zinc-Air battery?
The product catalog (http://www.mouser.com/ds/2/713/da14580-family-product-brief-772320.pdf) states "it can run from voltages as low as 0.9 V: ideal for running from single-cell or Zinc-air batteries." But what about the current. Can the Zinc-Air battery provide enough current to supply the microcontroller?

Assuming no other peripheral devices (i.e. looking only at powering the chip and associated components in boost mode), would the DA14580 be operational using a Zinc-air (A10 size) battery?

Thanks

Hi all，

A 4.7K pull-up resistor is used to connect the GPIO pin P0_2.We set the pin as high level input state,however,the voltage between the pullup resistor is not zero.So the resistor comsumes about 10 uA.
The 4.7K pull-up resistor connecting the GPIO pin P0_4 and P2_0 comsumes no current.

Should I use another pin to decrease the standby current?
