32-bit external device connection issue

Hi,

I am new to RZ family MPUs. I am designing high speed data acquisition board.

I want to write data from external 32-bit ADC (dual channel 2x16bit, parallel interface) at 65 MHz frequency rate via DMA into MPU's internal RAM (bare metal programming). Is it possible to implement with RZ/A1L group MPUs?

I have assumed that for such a purpose the MPU should have a 32-bit wide external bus interface. Do I have to connect the external ADC to AHB32IC3 bus or I could use two other peripherial 16-bit wide buses for high-speed simultanious data transmission?

In other words, do I have to connect the ADC to 32-bit wide data bus in place of parallel SDRAM?

Thank for your help
