SC16IS752IBS

The SC16IS752IBS is a Dual UART with I²C-bus/SPI interface, 64 bytes of transmit and receive FIFOs, IrDA SIR built-in support. It offers data rates up to 5Mbps, low operating and sleeping current, it also provides the application with 8 additional programmable I/O pins. The device is ideally suitable for hand-held, battery-operated applications. This chip enables seamless protocol conversion from I²C-bus/SPI to RS-232/RS-485 and is fully bi-directional. The 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.

• Dual full-duplex UART
• Baud rates up to 5Mbps in 16x clock mode
• Auto hardware flow control using RTS/CTS
• Auto software flow control with programmable Xon/Xoff characters
• Single or double Xon/Xoff characters
• Automatic RS-485 support
• Built-in IrDA encoder and decoder interface
• Transmitter and receiver can be enabled/disabled independent of each other

Applications

Automation & Process Control, Portable Devices, Consumer Electronics

Warnings

All input and output pins are protected against ESD under normal handling. When handling ensure that the appropriate precautions are taken.
