MT46H32M16LFCK-6 IT

Product Summary

The MT46H32M16LFCK-6 IT is a 512mb mobile DDR. This document describes critical product differences associated with the 512Mb Mobile (LP) DDR SDRAM product as it transitions from 95nm process technology to 78nm process technology. Micron makes every effort to ensure that new replacement products have full functional compatibility with previous products. The MT46H32M16LFCK-6 IT is accomplished through design, ATE characterization, and target system validation when possible. It is therefore unlikely that a system that has been designed with a Micron LP DDR SDRAM product will have any problems with a Micron replacement product. Micron does recommend, however, that the MT46H32M16LFCK-6 IT design be fully evaluated with the final version of the new product prior to conversion.

Parametrics
