TMS320 clones: has anyone tried them

[uer166]

Per title, has anyone tried to do anything with TMS320 clones such as :

They seem to be neat parts that can do lots of good stuff on the cheap, and wonder if it's similar to the Gigadevice/ST situation? Or something else (die copy instead of a re-implementation?). What do the tools look like? Is it binary compatible with TI?

Do you mean the chip like in the attachment?

Thats an actual TI part, or is trying to be, the parts OP is talking about are something else: https://lcsc.com/product-detail/Digital-Signal-Processors-Controllers-DSPs-DSCs_Haawking-HXS320F28034PNT_C2859021.html

It says RISCV so it might be equivalent to how the GD32VF103 is to the GD32F103 and STM32F103. In that its quite a change, and likely won't be binary compatible.

Nay. Even the Chinese datasheets are inconvenient enough for me.

They seem to churn even more of C2000 look a likes with Risc-V core.

These are interesting.
I'm not sure what the use case for them would be, since they use different core architectures and the C2000 has a very odd core (16-bit is the smallest addressable unit, etc...) which would mean code is extremely unlikely to work without a lot of checking and work.

Footprint compatibility, featureset compatibility (ePWM, HRPWM, etc.). Even if they have to rewrite most of the code, its worth it for some people.

TMS320F2802PZA seems to go for ~$8. So if you produce enough product using them, it might be worth it to port.
Dave recently had a teardown with a microinverter using TMS320. I'm sure they make massive quantities of those, its a huge market.
