LC73701M

Serial Interface Dialler

• The dial pulse make ratio can be specified to be either

33 or 39%.

• Wide operating voltage range

Overview

The LC73701M is a DTMP/pulse output dual-system

dialer CMOS LSI for use in push-button telephones. It

provides an on-chip serial interface and operates under the

control of data sent over that serial interface. The

LC73701M can be easily controlled by the system CPU

using this dedicated interface.

Pulse mode: V = 1.5 to 5.5 V

DTMF mode: V = 2.0 to 5.5 V

Package Dimensions

unit: mm

Functions

3095-MFP18

• Functions as a dialer that is controlled over a serial

interface.

[LC73701M]

• The built-in oscillator circuit (f

= 4.19 MHz) can use

OSC

either a crystal oscillator or a ceramic resonator as its

oscillator element.

• The adoption of a high-precision (±0.04%) DTMF

signal frequency divider circuit allows a ceramic

resonator to be used as the oscillator element.

• The buffer memory can store up to 32 digits of 5-bit

data.

• Mode change and pause commands can also be stored as

data in the buffer memory.

• Pauses can be inserted automatically on mode changes

(auto-pause).

• A pause can be cancelled during that pause.

• The mode change function supports changing from pulse

to tone (single direction).

SANYO: MFP18

• Generates all 16 DTMF signals.

• The pulse dialer output can be turned on or off

arbitrarily.

• The pulse dialer output circuit can be selected to be

either an n-channel open drain or a complementary

circuit.

• The pulse dialer muting function can be turned on or off

arbitrarily.

• A redial function is provided.

• Flash operation is supported. (Data can be received

during flash operation.)

• The flash time can be switched to be either 277 or 707

ms.

• The pause time can be switched to be either 2 or 4

seconds.

• Hooking pause operation is supported. (1.2 s or 801 ms)

• The dial pulse rate can be specified to be either 10 pps

or 20 pps.
