ML7005 Overview
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.
