Universal asynchronous receiver/transmitter (UART).

The UART has been around for a long time.
▶
Asynchronous, clock is assumed. No clock domain boundary to
cross!

Usually eight data bits plus optional parity. Two or three support
bits.
▶
There exist “standard” baud (bits/second) rates.
▶
Designed to be robust to clock offset/drift.
