GENERAL DESCRIPTION

The Z02205 V.22bis Modem Controller serves as the mo-

dem controller in embedded V.22bis modem applications.

A complete modem can be made by adding ZiLOG data

pump (Z02201), phone line interface, and the required DTE

interface. The Z02205 has been designed for low-cost use

and includes a glueless interface to the ZiLOG data pumps.

The Z02205 is ideal for applications where small size and

low power consumption are requirements.

The Z02205 operates over dial-up telephone connections,

provides auto-dial and ring detect, and operates in either

SYNC

or ASYNC modes.

The Z02205 includes AT command and modem control

firmware in on-chip ROM. It also includes enhanced wake-

up circuitry, programmable Watch-Dog Timers (WDT), and

low-noise/EMI options.

AT commands stored on-chip in ROM provide control over

the following modem controller functions:

Call progress monitoring

Handshake negotiation

Dial controls—pulse or tone

S-registers

Auto-answer and auto-dial

Guard tones

On-hook and off-hook

Auto-retrain

Standard Z02205 sample devices and demonstration boards

contain controller code tailored for operation on the North

American phone network. For production usage, customers

must modify the controller code to meet the requirements

of their particular country and application.
