SC16IS752IBS,128

SC16IS752IBS,128 is an I2C-bus/SPI bus interface to a dual-channel high performance UART offering data rates up to 5 Mbit/s, low operating and sleeping current; it also provides the application with 8 additional programmable I/O pins. This chip enables seamless protocol conversion from I2C-bus/SPI to RS-232/RS-485 and is fully bidirectional. It supports SPI clock speeds up to 4Mbit/s. The SC16IS752’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. It 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. Typical applications include factory automation and process control, portable and battery operated devices and cellular data devices.
