3. Introduction
This document states engineering specifications of both hardware and firmware of
DVDR520H.
DVDR520H adapts LSI DMN8652 chip, DMN-8652 is a single chip dual drive
(HDD/DVD) recorder processor. DMN-8602/DMN-8652 will be the evolutionary
product family after DMN-8600 and DMN-8650. In this sense, DMN-8602/8652 will
offer the same features as their predecessors, allow cost saving at the system level
due to integration, and offer more features at the C-Ware level.
