DS90UH929-Q1: Recommend EEPROM for using External Local EDID (EEPROM)

Nao,
The EVM user guide provides the socket dimensions for the EEPROM ('U3') but we do not recommend any specific parts. You can check online at sites such as Digikey, Mouser, or Avnet and find a standard part off the shelf.

Hi,

Please tell me the size of eeprom of lowest spec for edid.

Regards,

Nao

The EVM user guide shows the footprint (U3 - check the BOM for 110-13-308-41-001000) for the part and it provides the socket dimensions and the ratings.

I would like to know the memory data size, not foot print size.
Do you have a recommnd EEPRO?

Regards,
Nao

Hi, Palaniappan

I tested External local EDID (EEPROM) by your recommend EEPROM(BR24L64).
But, it does not work.

Did you test this EEPROM?
Could you please share that how to use EEPROM, if yes.

Regards,
Nao

Nao-san,
Can you explain what you mean by it does not work? It does not fit into the EVM or functionally the EEPROM is not working?
As I mentioned earlier we only provide the socket dimensions and the footprint in the EVM user guide, but we do not recommend or test with any specific parts.

Hi, Palaniappan


I confirmed a lot of EEPROMs for EDID.

www.rohm.com/.../plug-and-play

Many EEPROMs for EDID is under 8kbit and the read command is different the under 16K and the over 32k on EEPROM.
So, I guess we need to use the under 16kbit EEPROM.
