MN195001

Single-Chip Fax Engine LSI

Overview

The MN195001 reduces to a single chip CPU functions
related to facsimile control, peripheral device control
functions, and modem functions. The last include
complete fax/modem support for the ITU-T G3
recommandations V.29, V.27ter, and V.21 Channels 1
and 2.

The MN195001 consists of the following blocks: digital
signal processor (DSP), facsimile peripheral circuits,
analog circuits, DTE interface, clock generator, and dual­port RAM. Changing the contents of an external ROM
tailors the chip for a wide variety of facsimile applications.
