描述 Description

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.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)
