SC16IS750 Single UART with I2C-Bus / SPI Interface Module
It 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 andsleeping 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£¬ which makes it ideally suitable for 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 SC16IS740/750/760 's internal register set is backward-compatible with the widely used 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. This allows the software to reset the UART at any moment£¬ independent of the hardware reset signal.
