I need to use the I2S of uC to communicate the Codec with the full duplex mode.Can I use the two half-duplex I2S in STM32F07X (e.g., STM32F071CBT7TR) to get that? I know that in the STM32F4 series, this function can be achieved with two half-duplex I2S.

Yes. Use one as master, the other as slave, connect both clocks externally.

Thanks,
But why modify the SPI/I2S resource for this functionality in the STM32F4x family?(The means of provision can be internal connect I2S_SCK, I2S_WS of 2 I2S together)
In my opinion, Other than that ( connect both clocks externally), STM32F07x ( implements a full duplex I2S in the same way as STM32F4x. What else am I getting wrong?

Yes, it's a missed opportunity that woul make the 'F0 family better, but it is what it is.
