FEATURES

DESCRIPTION

The 73M2901/5V is a single-chip modem that

combines all the controller (DTE) and data pump

functions necessary to implement an intelligent

V.22bis data modem. This device is based on TDK

Semiconductor’s implementation of the industry

standard 8032 microcontroller core with a proprietary

multiply and accumulate (MAC) coprocessor; Sigma-

Delta A/D and D/A converters; and an analog front

end. The ROM and RAM necessary to operate the

modem are contained on the device. Additionally,

the 73M2901/5V provides an on-chip oscillator and

Hybrid driver.

Low overall system chip count. True one

chip solution for embedded systems

Low operating power (~250mW

5V,

automatic low power standby and power

down options available)

Internal ROM and RAM for normal operation

On chip optional hybrid driver

Designed for +5 volts (+/-10%)

Data speeds:

V.22bis – 2400bps

V.22, Bell 212 – 1200bps

V.21, Bell 103 – 300bps

The 73M2901/5V is a high performance, low

voltage, low power, single chip modem capable of

data transmission and reception through 2400bps.

The 73M2901/5V is intended for embedded

applications and battery operation. This device

offers options for a low power conventional 5 volt

design with optional internal hybrid and country

specific call progress support.

V.23 – 1200/75bps (w/ turnaround (PAVI))

Bell 202 – 1200bps

Bell 202 and V23 4-wire operations

Dynamic Range: -9dBm to –43 dBm

“AT” command set

Host access to modem port pins via AT

commands for custom I/O expansion

DTMF tone generation and detection

Call progress support with multinational

options (FCC68, CTR21, JATE…)

Caller ID capability

Blacklisting capability

Packaging: 32 pin PLCC or 44 pin TQFP
