ML7005 - DTMF Transceiver

General Description

The ML7005 is a multi-functional DTMF transceiver LSI with built-in a DTMF signal generator, a DTMF signal receiver, a call progress tone generator, a call progress tone detector, and a FAX (FX) signal detector.

Key Features

  • Wide range of power supply voltage : +2.7 V to +5.5 V.
  • Low power consumption Operating mode : 4.0 mA (VDD = 3 V) Typ. Operating mode : 5.0 mA (VDD = 5 V) Typ. Power down mode : 1 mA Typ.
  • The 4-bit processor interface supports both the Intel processor mode in which a read signal and a write signal are used independently of each other, and the Motorola processor mode in which a read signal and a write signal are used in common.
  • The DTMF receiver can select ei.

FEDL7005-01 Issue Date: Oct. 18, 2011 ML7005 DTMF Transceiver GENERAL DESCRIPTION The ML7005 is a multi-functional DTMF transceiver LSI with built-in a DTMF signal generator, a DTMF signal receiver, a call progress tone generator, a call progress tone detector, and a FAX (FX) signal detector. Each functional block can be controlled by an external MCU via a 4-bit processor interface. The ML7005 does not contains a modem. However, the DTMF system data transmission is possible at less than 66 bps by setting the DTMF receiver to the high-speed detection mode. The ML7005 operates with low-power consumption and is suitable for remote control systems, especially for ACR (Automatic Cost Routing) controllers. FEATURES • Wide range of power supply voltage : +2.7 V to +5.
