750 SC16IS750 Single UART With I2C-Bus/SPI Interface For Industrial Control<br> <br> SC16IS750 Single UART with I2C-bus/SPI interface<br> The SC16IS740/750/760 is a slave I2C-bus/SPI interface to a single-channel high<br> performance UART. It offers data rates up to 5 Mbit/s and guarantees low operating and<br> sleeping current. The SC16IS750 and SC16IS760 also provide the application with 8<br> additional programmable I/O pins. The device comes in very small HVQFN24, TSSOP24<br> (SC16IS750/760) and TSSOP16 (SC16IS740) packages, which makes it ideally suitable<br> for handheld, battery operated applications. This family of products enables seamless<br> protocol conversion from I2C-bus or SPI to and RS-232/RS-485 and are fully bidirectional.<br> The SC16IS760 differs from the SC16IS750 in that it supports SPI clock speeds up to<br> 15 Mbit/s instead of the 4 Mbit/s supported by the SC16IS750, and in that it supports<br> IrDA SIR up to 1.152 Mbit/s. In all other aspects, the SC16IS760 is functionally and<br> electrically the same as the SC16IS750. The SC16IS740 is functionally and electrically<br> identical to the SC16IS750, with the exception of the programmable I/O pins which are<br> only present on the SC16IS750.<br> The SC16IS740/750/760s internal register set is backward-compatible with the widely<br> used and widely popular 16C450. This allows the software to be easily written or ported<br> from another platform.<br> The SC16IS740/750/760 also provides additional advanced features such as auto<br> hardware and software flow control, automatic RS-485 support, and software reset. This<br> allows the software to reset the UART at any moment, independent of the hardware reset<br> signal.<br> <br>
