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?

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.

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.
