73K224L

V.22bis/V.22/V.21/ Bell 212A/Bell 103

Single-Chip Modem

April 2000

DESCRIPTION

The 73K224L is a highly integrated single-chip

modem IC which provides the functions needed to

construct a V.22bis compatible modem, capable of

2400 bit/s full-duplex operation over dial-up lines. The

73K224L offers excellent performance and a high

level of functional integration in a single 28-pin DIP

and 44-pin TQFP package. This device supports

V.22bis, V.22, V.21, Bell 212A and Bell 103 modes of

operation,

allowing

both

synchronous

and

asynchronous communication. The 73K224L is

designed to appear to the systems designer as a

microprocessor peripheral, and will easily interface

with popular single-chip microprocessors (80C51

typical) for control of modem functions through its 8-

bit multiplexed address/data bus or via an optional

serial control bus. An ALE control line simplifies

address demultiplexing.

Data

communications

normally occur through a separate serial port. The

73K224L is pin and software compatible with the

73K212L and 73K222L single-chip modem ICs,

allowing system upgrades with a single component

change.

The 73K224L operates from a single +5V supply for

low power consumption.

The 73K224L is ideal for use in either free-standing or

integral system modem products where full-duplex
