Dear IPMC support,

I would like to test the EEPROM (AT24C64D) which is on the testPAD. What is its I2C address?

Cheers,

Fatih

Hello Fatih,

In the document “Schroff Pigeon Point Management Mezzanine, (PPMM-700R) Bench Top Carrier, Technical Specification ” the address 0xAE is mentioned but I am all but certain that this is the correct source of information. Ralf and Stefan will be back from vacation in ~one week. Maybe they can give you an answer with a higher level of confidence.

Cheers,

Markus

Hi Markus,

It seems plausible, the high nibble is 1010 (Ah) (i.e. device type Identifier)

May be, by looking at the IPMC testPAD schematic, you could tell me how the A0, A1 and A2 pins of the EEPROM are hard-wired?

Cheers,

Fatih

Hello Fatih,

Here is the part of the schematics that I could find:

Does that help?

Hi Markus,

Yes, that helps me.

Thanks.
