Main differences between ESP32-S3 Rev. 0 and Rev. 1?

Hi all,

I would like to know what's the major differences between ESP32-S3 Rev. 0 and Rev. 1? It seems like the development boards I've got is Rev. 0. If I use these development boards and develop firmware for Rev. 1 silicon, is there anything I need to be specifically taken care of?

If you use devboards, there's nothing in particular you need to worry about: the rev0 and rev1 variations are mostly optimizations in the analog circuitry.

Thanks. Are you sure there's no breaking changes or significant difference particularly on SDMMC, PSRAM, RMT, DMA and LCD?

The reason I need to know this is because I am working on some projects that are highly rely on RAM performance and timing control. If there are any differences on those peripherals then we might need to prepare some workarounds.
