1. General description
The SC16IS741A
1
is a slave I
2
C-bus/SPI interface to a single-channel high performance
UART. It offers data rates up to 5 Mbit/s and guarantees low operating and sleeping
current. The device comes in the TSSOP16 package, which makes it ideally suitable for
handheld, battery operated applications. This device enables seamless protocol
conversion from I
2
C-bus or SPI to and RS-232/RS-485 and are fully bidirectional.
The SC16IS741A’s internal register set is backward-compatible with the widely used and
widely popular 16C450. This allows the software to be easily written or ported from
another platform.
The SC16IS741A also provides additional advanced features such as auto hardware and
software flow control, automatic RS-485 support, and software reset. This allows the
software to reset the UART at any moment, independent of the hardware reset signal.
