TCA8424

Other Parts Discussed in Thread: TCA8424, LM8333

Dear all,

One of my customer would like to know additional information on the TCA8424,

• Does it integrated a detection function Keypad Overrun? (As does the LM8333)

• What is the size of the FIFO

• Can be used without having programmed by OTP?

• What information to be programmed by OTP?

Thanks for your support

  • Hi,

    • Does it integrated a detection function Keypad Overrun? (As does the LM8333)

    • TCA8424 does not have the Keypad overrun feature integrated

    • What is the size of the FIFO

    • There is no FIFO on this device

    • Can be used without having programmed by OTP?

    • To use TCA8424with the built-in drivers of Windows 8, the OTP needs to be programmed. If custom drivers are being developed, then OTP programming may not be necessary

    • What information to be programmed by OTP?

    • Please refer to the app note 

    Thanks,

    Rajan
