Power supply input for the digital section.
Remocon function input. An high level at this pin is detected as a non pressed key, while a low
level is detected as a pressed key.
Third positive high impedance input to transmit preamplifier for microphone connection.
Third negative high impedance input to transmit preamplifier for microphone connection.

Positive high impedance input to transmit pre-amplifier for microphone connection.
Negative high impedance input to transmit pre-amplifier for microphone connection.
Analog Ground: All analog signals are referenced to this pin. GND and GNDA can be connected
together for low cost applications (see STw5093 Power Supply Notes).
Second Positive high impedance input to transmit pre-amplifier for microphone connection.
Second negative high impedance input to transmit pre-amplifier for microphone connection.
Power supply input for the V
Receive analog extra amplifier complementary outputs. These outputs can drive directly
earpiece transductor of 8Ω or 50nF. The signal at these outputs can be the sum of:
- Receive Speech signal from DR,
- Internal Tone generator,
- Sidetone signal.

A logic 1 written into DO (CR1) appears at LO pin as a logic 0
A logic 0 written into DO (CR1) appears at LO pin as a logic 1.
Pulse width modulated buzzer driver output.
Control Clock input: This clock shifts serial control information into CI and out from CO when the
CS- input is low, depending on the current instruction. CCLK may be asynchronous with the
other system clocks.
Chip Select input: When this pin is low, control information is written into and out from the
STw5093 via CI and CO pins.
Control data Input: Serial Control information is shifted into the STw5093 on this pin when CS- is
low on the rising edges of CCLK.
