ML7005
DTMF Transceiver
FEDL7005-01
Issue Date: Oct. 18, 2011
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 +5.5 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 either the high-speed detection mode (signal repeat time: more than
60 ms) or the normal detection mode (signal repeat time: more than 90 ms).
• Built-in call progress tone generator
• Built-in FAX signal (FX: 1300 Hz) detector
• The DTMF signal generator, DTMF signal detector, call progress tone generator, and call progress
tone detector can operate concurrently.
• Built-in 3.579545 MHz crystal oscillator circuit
• Package :
32- pin plastic SSOP (SSOP32-P-430-1.00-K) (Product name: ML7005MB)
