The basic difference between these two chipsets are: with D, means has an internal DDR. This DDR is 1G byte. It is enough for the basic functions. But it is not enough for some functions, like speed cam, and other functions.
We made a following picture to help you understand the difference. And why we use the A7L50, not the A7L50D.
Our solution is based on A7L50 and OV4689. If you need more information. We would be happy to share with you.
Have a good day!
