Changing EEPROM component for Jetson Nano Carrier Board?

[jean7]

Hey there,

We’re in the process of manufacturing our own edge devices, powered by Jetson Nano, but there are supply chain concerns around a couple of the components in the Reference design (the Dev Kit), we have a couple ideas that I’m hoping you guys would be able to shed some light on:

Here are the parts we are looking to replace.

EEPROM:
The Reference design specifies this part:

            AT24C02D-MAHM-T       Microchip Technology

            https://ww1.microchip.com/downloads/en/DeviceDoc/AT24C01D-AT24C02D-I2C-Compatible-Two-Wire-Serial-EEPROM-1Kbit-2Kbit-20006100A.pdf

Alternative Part we’re looking at:

            AT34C04-X5M-T                Microchip Technology

            https://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-8827G-SEEPROM-AT34C04-Datasheet.pdf

Our concern here is that the reference part has 2K worth of memory, whereas the alternative has 4K. This could have impacts on page sizes, and a few other areas of operation. Our program is built in Python and sits in Docker containers, so we do not have access to low-level memory management, and rely on Jetpack (the OS) for the low-level management.

So my question is thus:
Will changing the EEPROM component specs affect Jetpack, or can I go ahead with swapping the component?

Any help here would be MASSIVELY appreciated :)

Best,
JV

Hi, we don’t have recommendation on this as it is not validated on devkit. But in general, changing EEPROM should be no problem if you can w/r it correctly. So better to check its datasheet or check with vendor for anything should be noted. For nano, it is just a I2C device attached.
