750 SC16IS750 Single UART With I2C-Bus/SPI Interface For Industrial Control SC16IS750 Single UART with I2C-bus/SPI interface The SC16IS740/750/760 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 SC16IS750 and SC16IS760 also provide the application with 8 additional programmable I/O pins. The device comes in very small HVQFN24, TSSOP24 (SC16IS750/760) and TSSOP16 (SC16IS740) packages, making it ideally suitable for handheld, battery-operated applications. This family of products enables seamless protocol conversion from I2C-bus or SPI to RS-232/RS-485 and is fully bidirectional. The SC16IS760 differs from the SC16IS750 in that it supports SPI clock speeds up to 15 Mbit/s instead of the 4 Mbit/s supported by the SC16IS750, and it supports IrDA SIR up to 1.152 Mbit/s. In all other aspects, the SC16IS760 is functionally and electrically the same as the SC16IS750. The SC16IS740 is functionally and electrically identical to the SC16IS750, with the exception of the programmable I/O pins, which are only present on the SC16IS750. The SC16IS740/750/760 internal register set is backward-compatible with the widely used 16C450 UART. This allows software to be easily written or ported from another platform. The SC16IS740/750/760 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.
