IWRL6432: What is the Silicon Revision for my IRWL6432BOOST?

Part Number: IWRL6432
Other Parts Discussed in Thread: AWRL6432,

Tool/software:

I'm trying to determine what silicon revision is on my IWRL6432BOOST board, ES1.0 or ES2.0. I'm having trouble running the AWRL6432 In-Cabin Sensing demo.

Here is a photo of the markings on my board.I tried using the device errata page, but the numbers there do not seem to match up to mine.

Thanks.

Hi,

This is the TM4C programming chip on-board, not the IWRL6432. The IWRL6432 is on the other side of the board connected to the antennas.

Best,

Nate

Added an FAQ page as a result.

Hi Nate,

Thanks for your reply. It appears that mine is completely devoid of any markings.

Hi,

The markings on some chips can be quite feint. Try focusing the light on the IC.

When did you purchase the board too? If it was recently, it's quite unlikely to be ES1.

Best,

Nate
