Part Number: TCA8424

Hello,

Our customer asked us to implement the programming support of TCA8424 to our programming tools. Could you send me the specification for burning the OTP memory?

Thank you in advance.

Hi Frantisek,

This document goes over how to create the OTP memory. This document has an example keyboard map on page 5. It also shows how the memory should be laid out.

Let me know if you have any questions.

Best,

Chris

Hi Chris,

Thank you for response. I know this document, but there is not described how to burn the data into OTP memory (used I2C commands, etc.), I need exactly this description.

Best regards,

Frantisek

Hi Frantisek,

Are you using the EVM perchance? If you are can you tell me which MSP device you are using and which version of the EVM you are using. I can bring this into the lab and try to write up a guide for you on how to write to the OTP.

In the meantime I am looking for documentation on how to set this up. It seems like since this device is NRND we haven't made too much documentation on it.

Best,

Chris
