LM3880-Q1: Logic Bearing Device?

Go Bravos

Part Number: LM3880-Q1

Team,

Is the LM3880QMF-1AE/NOPB logic bearing?

I believe the reason for this question is because if it is programmable then there is a supply chain risk that my customer needs to manage/mitigate.

Thank you.

The sequencing order is stored inside the EPROM with polarity bit for the ATE test.

What kind of supply chain risk do you refer here?

Yihe,

Thank you. I believe the risk that they have to consider is that of intentional insertion of malicious hard/soft coding or defect to enable or cause failure, backdoors, etc.

Hello

The EPROMs used on our analog/mixed signal processes are “free”. They are created from process layers already existing in the process. As such, they are not optimized devices, which results in them being more radiation tolerant than a stand alone, optimized EEPROM.

We haven't heard a single case related to what they concerns.

Yihe
