Does i.MX27 support the 512Mbit LPDDR SDRAM W949D2DBJX5E?

Hello, I have used the SDRAM MT46H16M32LFB5-6 IT which is a 512Mbit, clock rate 166MHz, 4 Meg x 32bit x 4 banks LPDDR in my design previous, but now it is no stock. So I have to change it by using the W949D2DBJX5E as a replacement. The processor in my design is i.MX27, does it works when I connect to the W949D2DBJX5E which is a 512Mbit, clock rate 200MHz, 4 Meg x 32bit x 4 banks LPDDR?

In the other hand, do you have a list of SDRAM componet models or manufacturers that is supprted by i.MX27?

The SDRAM should be 512Mbit, 4 Meg x 32bit x 4 banks and the power supply is 1.8V.

If I change the clock rate from 166MHz to 200MHz, what changes should I do in my code?

Thanks a lot!
