I guess this micro-controller is so popular that it was just a question of time until it was ripped-off. | I guess this micro-controller is so popular that it was just a question of time until it was ripped-off. | ||
To check if this is a complete clone you could decapsulate the chip and compare the silicon die, or check the errata behaviour (I can't imagine they re-implemented it themselves, up to the mistakes). | To check if this is a complete clone you could decapsulate the chip and compare the silicon die, or check the errata behaviour (I can't imagine they re-implemented it themselves, up to the mistakes). | ||

+ | I'm a bit sad because the CS32F103C8 really only has the advertised 64 KB of flash, while the STM32F103C8 actually has 128 KB (e.g. what the STM32F103CB has), and when you have a lot of debugging strings in your firmware, you very soon reach the limit of the 64 KB. | ||
