1. Introduction

1.1

Scope

This document defines and describes all hardware functions of the MFC2000 chip. The MFC2000 design is based

on the MFC1000 design with many minor modifications/enhancements. It has several new key functions to

accomplish the following:

•

Support a full color MFP

•

Enhance connectivity to the PC

•

Provide an internal Fax Modem

•

Connect to external Conexant video chips

1.2

System Overview

The Conexant Multi-Functional Peripheral Controller 2000 (MFC2000) device set hardware, core code,

application code, and evaluation system comprise a full color Multi-Functional Peripheral (MFP) system

−needing

only a power supply, scanner, printer mechanism, and paper path components to complete the machine. The

standard device set hardware includes Conexant’s MFC2000 chip, Conexant’s SmartDAA or IA chip, and a

Printer Interface chip. Optionally, a Conexant video chip with VIP interface can be used to support the video

capture function. If V.17 or V.34 faxing without voice is required, the internal V.17/V.34 Fax Modem in the

MFC2000 chip is used and the MFC2000 is connected to the external Conexant SmartDAA or IA chip. If the

voice/speech function is required, the external Voice Fax Modem device from Conexant will be needed. Any other

external interface device can be supported by using the external ARM for CPU and DMA accesses or by using

the internal serial interface. An MFP system-level block diagram using the MFC 2000 is illustrated in Figure 1-1.
