SC9200
DTMF GENERATOR WITH MICRO-PROCESSOR INTERFACE
DESCRIPTION
The SC9200 tone generators are designed for µC interfaces. They can
be instructed by a µC to generate 16 dual tones and 8 single tones from
the DTMF pin. The SC9200A/AS provides a serial mode whereas the
SC9200B/BS contains a selectable serial/parallel mode interface for
various applications

Chip enable, active low.
The system oscillator consists of an inverter, a bias resistor, and the
required load capacitor on chip. The oscillator function can be
implemented by Connect a standard 3.579545MHz crystal to the X1 and
X2 terminals.
Negative power supply.
No connection.
Data inputs for the parallel mode.
When the IC is operating in the serial mode, the data input terminals
(D0~D3) are included with a pull-high resistor. When the IC is operating
in the parallel mode, these pins become floating.
Operation mode selection input
S/P =”H”: Parallel mode
S/P =”L”: Serial mode
Data synchronous clock input for the serial mode. When the IC is
operating in the parallel mode, the input terminal (CLK) is included with
a pull-high resistor. When the IC is operating in the serial mode, this pin
becomes floating.
Data input terminal for the serial mode. When the IC is operating in the
parallel mode, the input terminal (DATA) is included with a pull-high
resistor. When the IC is operating in the serial mode, this pin becomes
floating.
Output terminal of the DTMF signal.
Positive power supply, 2.0V~5.5V for normal operation.
