ST-LINK/V3 ?

photovore:
When updating my IAR compiler service pack I saw that ST-LINK V3 support was one of the new features. Is there any info concerning this new version of the debugger? I quite enjoy the integrated UART in the ST Dev Boards and was wondering when they would add the feature to their official hardware.  Higher SWD speeds also wouldn't hurt.

Looks like it's already for sale: https://www.aliexpress.com/item/New-STLINK3-st-link3-st-link-V3-STM32-STM8-emulator/32815460150.html :-DD

andersm:
The STM32CubeProgrammer manual gives 24000kHz SWD and 21333kHz JTAG frequencies for the ST-Link v3 (via).

That usually means 96MHz or higher core clock. What for?

It appears this is now in stock at both digikey and mouser:

https://nz.mouser.com/ProductDetail/511-STLINK-V3SET

Here is a recently added technical doc that was added to ST's website explaining the differences in the different ST-link versions, it includes info about the ST-Link V3:

Headline features:
Based on STM32F723IE processor
USB 2.0 HS interface (rather than FS on all older stlinks)
Integrated VCP port with frequency up to 15MHz (assuming this means up to 15mhz uart)
USB Bridge interface with support for: SPI/UART/I2C/Can?GPIO

In addition to this the STCubeProgrammer has been updated to V1.2 which apparently now fully supports the V3 hardware.
Assuming the 24MHz SWD frequency still stands, but cant find any more info on this.
