IWR1843: Pin out verification

Part Number: IWR1843
Other Parts Discussed in Thread: AWR1843

Hi,

Good day.

Our customer is using the IWR1843 and they found an error on the datasheet and they need verification on it. The pin SPIA_CS_N is said to be located on C13 (based on the pin attributes, page 15) however on the drawing it is located on E15. I would appreciate if you could let us know which is correct.

Thank you.

Regards,

Cedrick

Cedrick,

E15 is correct for SPIA_CS_N, C13 is the ADC channel. It has been corrected in AWR1843 but need to be corrected in IWR1843.

Thanks and regards,
