TXS4555: TXS4555

Part Number: TXS4555
Other Parts Discussed in Thread: MSP430FR4133

Hi everyone,

in the implementation phase of one of our projects, I need to connect the TXS4555 component with the MSP430FR4133 microcontroller.

It is true that in the TXS4555 datasheet there are the three pins I/O, RST and CLK but I could not understand how to connect them to the MSP430FR4133 microcontroller.

  1. Is it possible to connect these two components?
  2. If yes, which pin of the microcontroller should I use?

Thanks for your collaboration.

Best regards

Davide Ciannamea

    Hi David,
    Welcome to e2e.

    Is this a generic voltage translation application?
    What are the voltage levels on the MCU and the peripheral?
    TXS4555 is a application specific device used for SIM card connectivity.
    There are other voltage translation devices available for generic usage. Please let me know more details about the system and your interface used.

    Hi Shreyas,
    thank you for your response.

    Is this a generic voltage translation application? No
    What are the voltage levels on the MCU and the peripheral? 3.7 V

    I want to allow our remote systems to be able to communicate with the device through the SIM card and send it appropriate AT commands, according to the ETSI standard.

    Best regards

    Hi Davide,

    This device is used for intefacing with the SIM(3G) card and the baseband processor. The SIM card has these 3 signals which is used to connect with the corresponding pins in the baseband processor(SOC).
    A MCU is a generic processor and may not have these specific signals for SIM card interconnectivity. You could use TXS0104 as a generic level translator for interfacing.
