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.

Just a footnote (before you get answer from Nordic support team that Nordic never discus future products and roadmaps openly on this forum;): nRF51 is 5-6 years old design on ARM Cortex-M0, you should already now move to nRF52 which is ARM Cortex-M4F. Hard to say what would be the benefits of utilizing new super duper M23/33 but upcoming nRF52840 (still on ARM Cortex-M4F but with USB, full BT5 LE radio PHY feature set and IEEE 802.15.4 and ARM TrustZone CC310) - which has engineering samples out there for almost a year and should have production version with volumes in the distribution channels almost every day - seems to satisfy all the needs of low-power non-wifi radio chip today (in my opinion).
