PI7C9X760ACLEX

The PI7C9X760 is a I2C-bus/SPI to a single-channel high performance UART bridge controller. It offers data rates up to 33 Mbps and guarantees low operating and sleeping current. The PI7C9X760 also has up to 8 additional programmable general purpose I/O [GPIO] pins. The device comes in very small TSSOP24 packages, which makes it ideally suitable for cost efficient, handheld, battery operated applications. These UARTs provide a bridge for protocol conversion from I2C -bus or SPI to and RS-232/RS-485 and are fully bidirectional. The PI7C9X760 supports SPI clock speeds up to 33 Mbps and IrDA SIR up to 1.152 Mbit/s. PI7C9X760’s internal register set is backward-compatible with the widely used and widely popular 16C450 UART. The PI7C9X760 also provides additional advanced features such as auto hardware and software flow control, automatic RS-485 support, support for fractional baud rates and software reset. This allows the software to reset the UART at any moment, independent of the hardware reset signalThis allows the software to reset the UART at any moment, independent of the hardware reset signal.
