750 SC16IS750 Single UART With I2C-Bus/SPI Interface For Industrial ControlSC16IS750 Single UART with I2C-bus/SPI interfaceThe SC16IS740/750/760 is a slave I2C-bus/SPI interface to a single-channel highperformance UART. It offers data rates up to 5 Mbit/s and guarantees low operating andsleeping current. The SC16IS750 and SC16IS760 also provide the application with 8additional programmable I/O pins. The device comes in very small HVQFN24, TSSOP24(SC16IS750/760) and TSSOP16 (SC16IS740) packages, which makes it ideally suitablefor handheld, battery operated applications. This family of products enables seamlessprotocol conversion from I2C-bus or SPI to and RS-232/RS-485 and are fully bidirectional.The SC16IS760 differs from the SC16IS750 in that it supports SPI clock speeds up to15 Mbit/s instead of the 4 Mbit/s supported by the SC16IS750, and in that it supportsIrDA SIR up to 1.152 Mbit/s. In all other aspects, the SC16IS760 is functionally andelectrically the same as the SC16IS750. The SC16IS740 is functionally and electricallyidentical to the SC16IS750, with the exception of the programmable I/O pins which areonly present on the SC16IS750.The SC16IS740/750/760s internal register set is backward-compatible with the widelyused and widely popular 16C450. This allows the software to be easily written or portedfrom another platform.The SC16IS740/750/760 also provides additional advanced features such as autohardware and software flow control, automatic RS-485 support, and software reset. Thisallows the software to reset the UART at any moment, independent of the hardware resetsignal.
