NXP Advanced UARTs

SC28L201 and SC28L202

The NXP Advanced UARTs SC28L201

and SC28L202 perform bit-by-bit, real-

time error checking during transmission.

They check data for accuracy as it’s be-

ing sent, so the processor doesn’t have

to review data when it returns.

Data sent by the transmitter is returned

by the remote receiver. During its return,

the data is compared, about one bit-

time later, with the data just sent. The

arbitration block examines all inter-

rupting sources and delivers, based on

highest value or priority, the condition

and identity of each source. Any errors

immediately generate an interrupt.

As a result, the processor doesn’t have

to evaluate transmission status, it simply

reads the dynamic arbitration register.
