STSAFA110S8SPL02

Overview

The STSAFA110S8SPL02 is an authentication chip and IoT secure element manufactured by STMicroelectronics. It operates within a supply voltage range of 1.8 V to 5.5 V and functions in industrial-grade environments across temperatures from -40°C to +105°C. The device utilizes an I2C interface for communication and is housed in an 8-SOIC package with a width of 3.90 mm. It serves as a highly secure solution providing authentication and secure data management services, certified under Common Criteria EAL5+.

Feature Summary

• CC EAL5+ AVA_VAN5 Common Criteria certification for high security assurance
• Supports Elliptic Curve Cryptography (ECC) with NIST or Brainpool 256-bit and 384-bit curves
• Integrated active shield and environmental parameter monitoring for fault protection
• I2C interface operating on 8-SOIC surface-mount package

Applications

• Authentication for consumables and peripherals
• Security for Internet of Things (IoT) connected objects
• USB Type-C power delivery charger authentication
• Qi over-the-air charger security

Procurement Notes

Verify the specific ordering suffix SPL02 against official documentation to confirm packaging details such as tape and reel specifications. Ensure compatibility with the required I2C bus speeds and voltage levels before integration. Confirm that the industrial temperature grade meets the operational requirements of the target environment.

Selection Notes

Select this component when CC EAL5+ certification is mandatory for platform integrity. It is suitable for applications requiring strong device authentication and secure channel establishment via TLS handshake. Consider the 8-SO package constraints and I2C interface limitations compared to SPI alternatives if higher speed is needed.

Part Context

This part belongs to the STSAFE-A110 series, which provides turnkey secure element solutions running on a secure operating system. The series is designed to protect OEMs against cloning and counterfeiting through pre-provisioned secrets and certificates within a trusted supply chain.
