Nordic intend to use Cortex-M23 and Cortex-M33?

[Carlos Delfino]

I just bought a nrf51 dk to master this wonderful SoC series.

For now I intend to keep my research and studies with Bluetooth 4.1, but would like to prepare for a jump to the next version. And the following doubt arose.

Does Nordic intend to launch some series similar to nRF5 with Cortex-M23 and Cortex-M33 microcontrollers?

Thank you.

Well I'm one of these old-fashion morons who believe that no embedded system should compute trigonometry or other things but if you really need it then yes, M4F has some DSP instructions which can help. Still I estimate this as 1% of so called "IoT" and similar applications, all the rest can and should do data processing elsewhere (in the mobile up or in the backend).

Point is: chips like Nordic's nRF5x has not only ARM Cortex-M architecture but also proprietary RF block design and other HW peripherals. To migrate it to new architecture is already big step so it happens in ~3-year cycles. It must be really strong reason to go to M23/33 (although it would be great to have even more secure HW features not only CryptoCell accelerator...)
