1. Introduction:

The SC16IS740/750/760 is a single channel high performance UART from the I2C bus/SPI interface. It provides data rates up to 5 megabits per second and guarantees low operating and sleep currents. The SC16IS750 and SC16IS760 also provide eight additional programmable I/O pins for the application. The device has very small hvqfn24, tssop24 (sc16is750/760) and tssop16 (sc16is740) packages, which makes it ideal for handheld and battery operated applications. This family of products implements 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 of up to 15 Mbit/s instead of the 4 Mbit/s supported by the SC16IS750, and in all other respects it supports IRDA SIRs up to 1.152 Mbit/s. The SC16IS760 is identical in function and electrical to the SC16IS750. The SC16IS740 is identical in function and electrical to the SC16IS750 except for the programmable I/O pins present on the SC16IS750. The SC16IS740/750/760's internal register set is back-to-back with the widely used and popular 16C450. This allows software to be easily written or ported from another platform.

The SC16IS740/750/760 also offers other advanced features such as automatic hardware and software flow control, automatic RS-485 support, and software reset. This allows the software to reset the UART at any time without being affected by the hardware reset signal.
