I am looking for MCU with high speed function

[HHo.2]

I found that the ST72681 8-bit MCU has HS function. Is there any support for this MCU? Or is there a related follow-up product?

ST72681 dose not seem to be a STM product.

It was a STM product

>>Or is there a related follow-up product?

That's a bit vague. What's the end goal/product here? The Flash market has evolved a bit in the last 15 years.

Unlikely to be a drop-in replacement. There are perhaps some low cost Chinese or Taiwanese USB Flash drive type parts. Perhaps something from SMSC / Microchip?

Can you use eMMC memories, and STM32F723 ?
