| SENT | N | 2 | Single ended | Single conductor, with 5 V power supply and ground | async. transmission, | 5 m | |||
| SPC | Y | 5 | Single ended or | Single conductor, with 5 V power supply and ground, shielded when using higher speeds | sync. and async. transmission, | ~0.5 m | 5 m | same as SENT | |
| I3C | Y | 127 | Single ended or | 12 500 kbits/s | |||||
| SPI | Y | Single ended | variable up to ~10000 kbit/s |
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.
