Protocol: to digitally communicate over a single cable with single-wire components
Single-wire's 3 components:
an external MCU
wiring and associated connectors
the STOD03AS device with a dedicated single-wire pin.
Fully digital signal
No handshake needed
Protection against glitches and spikes though an internal low pass filter acting on falling
edges
Uses a single wire (plus analog ground) to accomplish both communication and power
control transmission
Simplified design with an interface protocol that supplies control and signaling over a
single-wire connection to set the output voltages.
Single-wire protocol uses conventional CMOS/TTL logic levels (maximum 0.6 V for
logic “zero” and a minimum 1.2 V for logic “one”) with operation specified over a supply
voltage range of 2.5 V to 4.5 V
Both master (MCU) and slave (STOD03AS) are configured to permit bit sequential data
to flow only in one direction at a time; master initiates and controls the device
Data is bit-sequential with a START bit and a STOP bit
Signal is transferred in real time
System clock is not required; each single-wire pulse is self-clocked by the oscillator
integrated in the master and is asserted valid within a frequency range of 250 kHz
(maximum).
The negative output voltage levels are selectable within a wide range (steps of 100 mV)
The device can be enabled / disabled via S
