Thanks for reply. Only issue is both DDR2/DDR3 don't have good life cycle and many manufacturers are obsoleting them. Hence wanted to double check as some other QorIQ series does support. Is there any part similar to P1021 with DDRL support.
Try to check the datasheet of the DDR3L devices you are going to use. As far as I know, most of the DDR3L memory devices (if not all) support 1.5V supply. This means that DDR3L can be used with the P1021, however power dissipation will be higher.
