LMP91000 I2C interface pins

Other Parts Discussed in Thread: LMP91000

Hi,

I am in need to identify which pins specifically are the SCL, SDA, and MENB on your LMP91000 board. Our group cannot read this from the users guide (or the board) and this is not listed in the data sheet.

We are looking to connect this board with another I2C interface board. Can someone from TI please let us know.

Best.

Hi Marie,

there are two possibilities.

You can find these 3 signal as test points in the lower right corner of the board, labeld TP_SCL, TP_SAD and R_MENB (the left pin).

Alternatively they are also connected to the 16 pin header (lower right corner), pin 12 = SCL and pin 11 SDA.

Hope this helps

Andreas

Could you be more specific regarding location of R_MENB? When you state the left pin, in what orientation are you looking at the board?

Hi Marie,

I am looking to the board, so you can ready the text printed on it.. The 4 BNC connectors are on the top and the two connectors for the ADC board on the right side of the board.
