NXP SC16IS740IPW,112

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, which makes it ideally suitable for handheld, battery operated applications. This family of products enables seamless protocol 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 to 15 Mbit/s instead of the 4 Mbit/s supported by the SC16IS750, and in that 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'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 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.
