Single UART with I2C-bus/SPI interface, 64 bytes of transmit and receive FIFOs, IrDA SIR built-in support

The SC16IS741A is a follower I²C-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 I²C-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.
