SLB9672XU20FW1612XTMA1

Application Specific Microcontrollers Overview

The SLB9672XU20FW1612XTMA1 is an OPTIGA TPM security controller from Infineon Technologies, designed for embedded systems requiring robust authentication and data integrity. It implements the Trusted Computing Group (TCG) TPM 2.0 specification to protect computing platforms. The device features a 32-bit architecture with non-volatile memory storage for cryptographic keys and platform configuration registers. It supports I2C interface communication with a maximum clock frequency of 100 kHz. Operating within a voltage range of 3 V to 3.6 V, it functions reliably across temperatures from -40 °C to +85 °C. The component is housed in a UQFN-32 package, providing a compact solution for IoT and industrial applications.

Application Specific Microcontrollers Procurement Notes

Verify the specific firmware revision suffix against official Infineon documentation to ensure compatibility with required security protocols. Confirm that the UQFN-32 package dimensions match the target PCB footprint design. Check for any specific ordering suffixes that may indicate different packaging options or regional compliance variations. Ensure supply chain sources are authorized distributors to guarantee component authenticity and traceability.

Application Specific Microcontrollers Selection Notes

Select this model when an I2C interface is preferred over SPI for system integration constraints. The 100 kHz I2C speed is suitable for low-to-medium throughput security operations. Consider the UQFN-32 package size relative to available board space compared to VQFN alternatives. Verify that the 3V to 3.6V operating voltage aligns with the host system's power rails without requiring additional level shifting.

Application Specific Microcontrollers Part Context

This part belongs to the OPTIGA TPM SLB 9672 family, which offers variants with both SPI and I2C interfaces. The 'XU' designation typically indicates the UQFN-32 package and I2C interface combination. Other family members like the SLB9672AU20 series share similar core functionalities but may differ in interface type or specific firmware versions. This component serves as a hardware root of trust for modern embedded computing architectures.

Application Specific Microcontrollers Replacement Considerations

Direct replacements must maintain TCG TPM 2.0 compliance and identical interface specifications. The SLB9672XU20FW1613XTMA1 is a related variant within the same product line; verify if firmware differences impact application requirements. Cross-reference pinouts and electrical characteristics carefully before substituting any other security IC.
