Supports Secure Boot and Secure Key Storage functions

[Donald Song]

NRF52832, nRF52840 is under consideration for development.
Because of the implementation of Secure Boot and Secure Key Storage capabilities, we want to choose the nRF52840 product.

1. nRF52840 product is supported by trust zone, please check if both Secure Boot and Secure Key Storage are supported.
For your reference, ST is specified in the product spec as below.

2. Can't nRF52832 products implement Secure Boot and Secure Key Storage? If it's possible, please let me know the document you want to guide.

Hello, 

The nRF52-series does not support Trust Zone. Currently Nordic Semiconductor provides two Arm Cortex M33 (Armv8-M architecture) devices, which support TrustZone, the nRF9160 and the nRF5340.

More information on the nRF9160 can be found here:

• Working with the nRF9160
• nRF9160 Product Specification

And more information on the nRF5340 can be found here:

• Working with nRF5340
• nRF5340 Product Specification

Samples for both products can be found in samples in our nRF Connect SDK (NCS). 

Kind regards,
Øyvind
