Audio DAC interface to controller

Other Parts Discussed in Thread: TLV320DAC3100

I am planning to implement Voice guide using TLV320DAC3100 DAC and LPC2138 controller. Voice recognition and mic circuitry is not there since voice will be stored in memory externally and this concept is used as voice assistant while operating instrument.

Above DAC has I2S (Inter IC Sound) interface for exchanging audio from host controller to DAC. Unfortunately,LPC2138 is not I2S supported as per datasheet.

So, Is there any other option to implement Voice guide using LPC2138?

How will be pin mapping in this case? For I2S MCLK,BCLK,WS and SDI pins are required to interface.

Please advise soon. Thank you in advance.
