96-bit Unique id of STM8AF52xx

[raja1]

Hello.

I want to read the 96 bit unique id of STM8AF5288TCY microcontroller.

I have gone through some resources like the data sheet of stm8s105c4.

This mentions that the unique id is present 0x48CD address.

I want to know the address at which it is present for STM8AF5288TCY microcontroller as the datasheet does not specify it.

I want to read it as :

#define SERIAL_NUM_ADDR 0x49CD

const uint8_t * const serial= (uint8_t *)SERIAL_NUM_ADDR;

Please help me in identifying this unique id for STM8AF5288TCY

Welcome, @raja, to the community!

simple reason: there is no 96bit unique identifier in the STM8AF52xx.

Hello @Peter BENSCH​ . Thank you.

My work requires me to provide a serial number for the ECU. I thought of using a serial number like this. Is there any other way to have a serial number from STM8AF52xx ?

In my opinion, you would have to take care of this yourself, e.g. by storing a serial number in EEPROM.

I would like to take this opportunity to point out again that the STM8A have been on NRND since 2021, so they will only be produced for a limited time. We strongly advise against using STM8A for new automotive projects.
