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:
Issues setting up HyperRAM S70KL1282 with STM32H735 (OP has problems, LCE's boards just worked with minor tweak)

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.
