Hello expert,

I found pin 51-59 position mismatch between 2 figure in the following document

CC2651R3SIPA SimpleLink Multiprotocol 2.4 GHz Wireless System-in-Package Module with integrated Antenna & 352-KB Memory datasheet (Rev. B)PDF|HTM

P7 figure shows

P75 figure shows

Which is the correct one?

Hi Fujinaka-san,

Both figures are correct. P7 shows the pins as if you were looking down at the chip. P75 show the pins as if you were picking up the part and looking up at it from the bottom.

Best regards,

Hello Bun,

No , your answer is not correct. For example, P7 shows vertically 51, 52, 53 but P75 shows horizontally 51,52,53...

Hi Fujinaka-san,

Pins 51-59 are GND pins (p8 in the datasheet), so the horizontal/vertical order of the diagram is not crucial - it is something that could be modified in the next revision for consistency, though.

Hello Zack,

I understand all pins are GND pins, so it it not crucial. However , customer needs define the pins , so please clarify now how TI will modify it.

I'll submit a ticket to have the drawing changed and be more consistent.

Hi Fujinaka-san,

Please tell the customer to follow P75 as P7 will be changed to match it to be consistent, but since it is all ground pads the numbering does not really matter.

Best regards,

Bun
