1 / 22 page FEDL7012-04-01 1Semiconductor This version: Sep. 2000 ML7012-04 2400 bps Single Chip Full Duplex Data Modem with Protocol 1/22 GENERAL DESCRIPTION The ML7012-04 is a single chip modem LSI device that enables data communication conforming to ITU-T recommendations V.22bis, V.22, and V.21. This device is equipped with the error correction protocol function conforming to MNP Class 4. (The MNP Class 4 can be used for V.22bis or V.22.) The ML7012-04 consists of high speed DSP, analog front end, and digital logic circuit. In addition, this device provides local analog loop testing, synchronous/asynchronous switching, dialing, and auto answering functions. The ML7012-04 has a serial interface as an external 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 ML7012-04 can easily implement a modem that can be controlled through the RS-232C interface. FEATURES • Conforming to ITU-T Recommendations V.22 bis, V.22, and V.21: Asynchronous • Error correction function conforming to MNP Class 4 • Serial interface: V.24 interface • AT commands (excluding automatic command speed detection) • Terminal data speed between DTE and DCE: 9600 bps, 2400 bps, 1200 bps, 300 bps • Character format: 10 bit/character • DTMF sending function • Pulse-dial control signal output • Call progress tone • Auto answering function • Built-in electronic HYB circuit (a line transformer can be directly coupled) • Single +3 V power supply • Power consumption: Typ. = 35 mA (V DD = 3.3 V) • Package: 64-pin plastic QFP (QFP64-P-1414-0.80-BK) (Product name: ML7012-04GA) * MNP is a registered trademark of Microcom Inc. |
