• I2C interface with support for PQC-protected firmware update mechanism
• Certified to FIPS 140-2 Level 2 and Common Criteria EAL 4+
• Supports symmetric algorithms (AES, SHA) and asymmetric algorithms (RSA, ECC)

Application Specific Microcontrollers Applications

• Embedded TPM implementations in IoT devices
• Secure boot and data protection for industrial controllers
• Authentication modules for edge computing platforms

Application Specific Microcontrollers Procurement Notes

Verify the specific firmware version suffix (e.g., FW2610 vs FW2624) against official Infineon documentation to ensure compatibility with required cryptographic standards and update mechanisms. Confirm package availability and lead times through authorized distributors as stock levels vary.

Application Specific Microcontrollers Selection Notes

Select this component when an I2C interface is preferred over SPI for space-constrained embedded designs requiring high-level security certifications. Ensure the host system supports the required voltage levels (3.0V–3.6V) and temperature ranges (-40°C to +105°C). Compare with SLB9670 series if SPI interface or lower power consumption is prioritized.

Application Specific Microcontrollers Part Context

This part belongs to the OPTIGA™ TPM SLB 9673 family, which represents Infineon's latest generation of TPMs featuring post-quantum cryptography protections. It succeeds earlier generations like the SLB9670, offering enhanced security features while maintaining compatibility with standard TPM interfaces.
