SLB9673XU20FW2610XTMA1

Application Specific Microcontrollers Overview

The SLB9673XU20FW2610XTMA1 is an OPTIGA TPM security controller from Infineon Technologies, designed for embedded systems. It implements the Trusted Computing Group (TCG) TPM 2.0 specification and features an I2C interface with a maximum clock frequency of 100 kHz. The device operates within a supply voltage range of 3 V to 3.6 V and supports non-volatile memory storage. It provides symmetric cryptography including SHA-256 and AES-256, as well as asymmetric algorithms such as RSA and ECC. The component is housed in a UQFN-32 package and is certified to FIPS 140-2 Level 2 and Common Criteria EAL4+ standards.

Application Specific Microcontrollers Procurement Notes

Verify the specific firmware version suffix against official Infineon documentation, as variations exist within the SLB9673 family. Confirm interface compatibility and package requirements prior to integration. Check current availability status through authorized distributors, as lead times may vary for this product line.

Application Specific Microcontrollers Selection Notes

Select this component when an I2C interface is required for TPM 2.0 functionality in space-constrained designs. Ensure the host system supports the 3 V to 3.6 V operating voltage range. Compare against SPI-based alternatives like the SLB9672 series if higher data throughput is necessary, noting that the SLB9673 is optimized for lower pin-count applications.

Application Specific Microcontrollers Part Context

This part belongs to the OPTIGA TPM SLB 9673 family, which includes variants with different firmware versions and interfaces. The 'FW26' designation indicates a specific firmware release optimized for embedded systems with post-quantum cryptography protection capabilities. Other family members include SPI-interface models like the SLB9672.

Application Specific Microcontrollers Replacement Considerations

Direct functional substitutes within the same interface type are limited to other SLB9673 variants with compatible firmware. For interface migration, the SLB9672 series offers similar cryptographic capabilities but utilizes an SPI interface instead of I2C.
