The SC16IS752 Serial Adapter 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 SC16IS752 chip enables seamless protocol conversion from I2C-bus/SPI to RS-232/RS-485 and is fully bidirectional.; The SC16IS752 supports SPI clock speeds up to 4 Mbit/s, and the SC16IS752 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.
; Dual full-duplex UART, I2C-bus or SPI interface selectable, 3.3 V or 2.5 V operation, Auto hardware flow control using RTS/CTS, Up to eight programmable I/O pins, Automatic RS-485 support (automatic slave address detection); SC16IS752 Serial Adapter Module 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.
