5 m
SPC[disambiguation needed][6] Y 5 Single ended or

Open collector

Single conductor, with 5 V power supply and ground, shielded when using higher speeds sync. and async. transmission,

variable up to ~150 kbit/s

~0.5 m 5 m same as SENT
I3C Y 127
SPI Y variable up to ~10000 kbit/s

(depends stronly on physical setup)

ZZ ZZ 9999999 ZZ ZZ 9999999 9999999

The number of nodes can be limited by either number of available addresses or bus capacitance. None of the above use any analog domain modulation techniques like MLT-3 encoding, PAM-5 etc.

PSI5 designed with automation applications in mind is a bit unusual in that it uses Manchester code.
