I use stm32l476rg and ST25 as tags. I need to use the read and write end to collect energy to make the low power control chip L4 work. Will this work successfully? |

ST25R3911B-DISCO开发板上的LC滤波电路为啥配置的截止频率是11.75MHZ?我们的NFC频率是13.56MHZ,是不是设置的比较低?
NFC 相互通信,并且要对通用设备不可见
The ST25DV04KC has an energy harvest pin which has about 5mA output power(Depends on the field from reader). If you have higher energy harvesting, you need the NFC WLC solution.
NFC for wireless charging - STMicroelectronics
So can I use energy harvest pin to make the low power control chip L4 work? I think it's the low power MCU
[md]It's not possible to power the L4 with ST25DV V_EH feature. You need to use the NFC WLC circuits to powe the MCU. For the NFC WLC please contact the distributors or local marketing.
