SC16IS741

www.DataSheet4U.com SC16IS741 Single UART with I2C-bus/SPI interface, 64 bytes of transmit and receive FIFOs, IrDA SIR built-in support Rev. 01 — 29 April 2010 Product data sheet 1. General description The SC16IS741 is a slave 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 SC16IS741’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 SC16IS741 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. 2.
