Hello everyone.I am currently considering using the STM32H735 AD converter.As shown in the figure, I have inserted a Schottky barrier diode and a 1kΩ resistor just before the ADC terminal pin for overvoltage protection.I was curious about the input i...

Hello everyone.I want to connect 8 SRAMs (2MB) to STM32H755XIH3 and use them as 16MB work memory.When connecting 8 memories (SRAMs) using FMC (devices more than the number of FMC_NE*), how should I connect and control them? If there are any similar c...

HelloThank you very much for the detailed explanation. And thanks for the link.I understand that I need an address decoder, as @Tesla DeLorean told me.I will continue to consider whether to go with 8 SRAMs or use the HYPERRAM that @LCE told me abou...

Hi LCEThank you very much.I will consider whether HYPERRAM matches our system.It is true that pattern design for 8 SRAM is troublesome.Thank you for the useful information.

Hello Tesla DeLoreanThank you for your reply.The SRAM I'm trying to use has two chip enable terminals.I was thinking of doing it without a decoder. I don't know if that's possible though.

Hello LCEThank you for your reply.It was very helpful for you to share your experience.I will reconsider this over the weekend.
