73K222AU

Single-Chip Modem

Modem with UART

April 2000

DESCRIPTION

The 73K222AU is a compact, high-performance

modem which includes a 8250A/16C450 compatible

UART with the 1200 bit/s modem function on a

single chip. Based on the 73K222L 5V low power

CMOS modem IC, the 73K222AU is the perfect

modem/UART component for integral modem

applications. It is ideal for applications such as

portable terminals and laptop computers. The

73K222AU is the first fully featured modem IC which

can function as an intelligent modem in integral

applications without requiring a separate dedicated

microcontroller. It provides for data communication

at 1200, 600, and 300 bit/s in a multi-mode manner

that allows operation compatible with both Bell

212A/103 and CCITT V.22/V.21 standards. The

digital interface section contains a high speed

version of the industry standard 8250A/16C450

UART, commonly used in personal computer

products. A unique feature of the 73K222AU is that

the UART section can be used without the modem

function, providing an additional asynchronous port

at no added cost. The 73K222AU is designed in

CMOS technology and operates from a single +5V

supply. Available packaging includes 40-pin DIP or

44-pin PLCC for surface mount applications.

FEATURES

•

Modem/UART combination optimized for

integral bus applications

•

Includes features of 73K222L single-chip modem

•

Fully compatible 16C450/8250 UART with

8250B or 8250A selectable interrupt emulation

•

High speed UART will interface directly with

high clock rate bus with no wait states

•

Single-port mode allows full modem and

UART control from CPU bus, with no

dedicated microprocessor required

•

Dual-port mode suits conventional designs

using local microprocessor for transparent

modem operation

•

Complete modem functions for 1200 bit/s (Bell

212A, V.22) and 0-300 bit/s (Bell 103, V.21)

•

Includes DTMF generator, carrier, call-

progress and precise answer-tone detectors

for intelligent dialing capability

•

On chip 2-wire/4-wire hybrid driver and off-

hook relay buffer

•

Speaker output with four-level software driven

volume control

•

Low power CMOS (40 mW) with power down

mode (15 mW)

•

Operates from single +5V supply
