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.
