UART IO Expander

Other Parts Discussed in Thread: TCA9535

Hi,

I can find the I2C IO expander like TCA9535.  How about UART IO EXPANDER?  Does TI have UART IO EXPANDER?  Please let me know.

Thanks and best regards,
M. HATTORI

    Hattori-san,

    Unfortunately I do not know of a device like this, although a lower-end MCU could be programmed for this purpose.  Generally I don't see much advantage to UART control verus I2C since both would use at least two communication wires (SDA/SCL vs. TX/RX, plus interrupt line if needed), and the I2C implementation is usually simpler.  May I please ask the reason why you are looking for UART control instead?

    Thank you,
