Hi

I'm designing a PCB using the STM32H735 based on the eval kit STM32H735G-DK.

Since the HyperRAM  S70KL1281 on the eval is EOL I'm looking for an alternative

I have read a few posts with issues on this subject and I'm usure which part i should go with

I have identified following candidates from posts:

S70KL1282 

S27KL0642 (64Mbit)

APS12808L-3OBM

both 128 or 64Mit will be fine. Do you have recommendation on this? 

Thanks

Kristian Vang

    from Infineon AN229785: Migrating from S70KL1281/S70KS1281 to S70KL1282/S70KS1282

    It's a shame Infineon doesn't recommend a replacement part on the product page when they EOL. I thought that was standard practice.

     

    Also look at these threads:

    S70KL1281 is not hard to find

    I had the same problem, I have the selected the S70KL1282, have my custom boards now for 4 weeks.

    I only changed the latency from 6 to 7, everything running smoothly.
