Cwire Serial Interface
AnalogicTech's S
2
Cwire serial interface is a propri-
etary high-speed single-wire interface available
only from AnalogicTech. The S
2
Cwire interface
records rising edges of the EN/SET input and
decodes into 16 different states. Each state corre-
sponds to a voltage setting on the FB2 pin.

Cwire Serial Interface Timing
The S
2
Cwire serial interface has flexible timing.
Data can be clocked-in at speeds up to 1MHz. After
data has been submitted, EN/SET is held high to
latch the data for a period T
LAT
. The output is sub-
sequently changed to the predetermined voltage.
When EN/SET is set low for a time greater than
T
OFF
, the AAT1232 is disabled. When disabled, the
register is reset to the default value, which sets the
FB2 pin to 0.6V if EN is subsequently pulled high.
