STMicroelectronics STSAFE-A110 Authentication IC

STMicroelectronics STSAFE-A110 Authentication IC is a highly secure solution that acts as a secure element providing authentication and secure data management services to a local or remote host. The STSAFE-A110 consists of a full turnkey solution with a secure operating system running on the latest generation of secure microcontrollers. The STSAFE-A110 supports a wide range of security features, including authentication, secure-channel key establishment, signature verification, and symmetric keys. The device comes with a host integration code tested with STM32 microcontrollers. It can also be ported to a wide range of general-purpose microcontrollers or microprocessors. This integration code includes a command wrapper and examples for the most common use cases.

The STMicroelectronics STSAFE-A110 Authentication IC is offered in 8-lead, ECOPACK-compliant, SO8N and UFDFPN packages.
