Additional embedded secure element (eSE)

The ST4SIM-200M is able to combine the eSIM solution with an embedded secure element (eSE) section inside

the same chip.

This eSE section is used to provide secure storage, cryptographic services, and so on via Java® Card applets.

The eSE section is accessible through a dedicated serial peripheral interface (SPI) protocol and the eSIM uses

the ISO/IEC 7816 protocol in parallel. Consequently, the eSE is only available on WLCSP packages including ISO

and SPI protocols.

The embedded secure element is optional and configurable.

Contact the local STMicroelectronics sales office for more details on the pin configuration.
