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
The Z02205 includes
firmware in on-chip ROM. It also includes enhanced wake-
up circuitry, programmable Watch-Dog Timers (
low-noise/EMI options.
AT commands stored on-chip in ROM provide control over
the following modem controller functions:

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.
