ML7012-06
2400 bps Single Chip Full Duplex Data Modem with Protocol
FEDL7012-06-02
Issue Date: Jun. 28, 2004
GENERAL DESCRIPTION
The ML7012-06 is a single chip modem LSI device that enables data communication conforming to ITU-T
recommendations V.22bis, V.22 and V.21. This LSI is also equipped with the error correction protocol function
complying with MNP-class 4. (The MNP-class 4 is available in V.22bis or V.22 mode.)
The ML7012-06 consists of high speed DSP, analog front end, and digital logic circuit. In addition, this device
provides local analog loop testing, synchronous/asynchronous converter, dialing, and auto answering functions.
The ML7012-06 has an external serial interface. When integrated into the system, it is controlled from a control
CPU through a serial interface (e.g. UART). By connecting a level converter, the ML7012-06 can easily
implement a modem that can be controlled through the RS-232C-interface.
