SLB9670XQ20FW760XUMA1

Application Specific Microcontrollers Overview

The SLB9670XQ2.0 is a Trusted Platform Module (TPM) compliant with TCG Family 2.0 specifications, designed for computing platforms and embedded systems. It features an SPI interface supporting transfer rates up to 43 MHz at VDD = 3.3V or 22.5 MHz at VDD = 1.8V. The device provides hardware-based security including a Random Number Generator (RNG) per NIST SP800-90A, 24 PCRs using SHA-1 or SHA-256, and minimum 6962 bytes of free NV memory. It supports up to 64 active sessions and includes built-in Linux Kernel support. Certified under FIPS 140-2 Level 2 and Common Criteria EAL4+, it operates in the enhanced temperature range of -40°C to +85°C within a PG-VQFN-32-13 package.

Application Specific Microcontrollers Procurement Notes

Verify the specific firmware version associated with the XQ2.0 suffix against the manufacturer's current documentation. Confirm that the enhanced temperature rating (-40°C to +85°C) aligns with the target application environment requirements before finalizing procurement.

Application Specific Microcontrollers Selection Notes

Select the SLB9670XQ2.0 over the standard VQ2.0 variant when operation in temperatures below -20°C is required. Ensure the host system supports the SPI interface mode 0 and can provide the necessary voltage levels (1.8V or 3.3V). Verify compatibility with existing BIOS/UEFI implementations for platform qualification.

Application Specific Microcontrollers Part Context

The SLB9670XQ2.0 belongs to the OPTIGA™ TPM SLB 9670 product family from Infineon Technologies. It serves as a standardized security controller for identifying and authenticating computing platforms. The 'X' designation specifically indicates the enhanced temperature grade compared to the standard 'V' grade within the same package footprint.

Application Specific Microcontrollers Replacement Considerations

The SLB9670VQ2.0 is pin-compatible but offers a standard temperature range (-20°C to +85°C). For direct replacement in environments requiring lower temperature operation, only the SLB9670XQ2.0 variant is suitable. No other cross-model substitutes are documented.
