ST33HTPH2X32AHD4

Application Specific Microcontrollers Overview

The ST33HTPH2X32AHD4 is a flash-memory-based Trusted Platform Module (TPM) compliant with TCG TPM Library specifications 2.0, Level 0, Revision 159. It integrates an Arm SecurCore SC300 processor and operates within a supply voltage range of 1.62 V to 3.6 V. The device supports SPI interfaces at speeds up to 33 MHz and features fault-tolerant firmware loading for self-recovery. It includes hardware protection mechanisms such as active shields and environmental sensors, targeting certifications including Common Criteria EAL4+ and FIPS 140-2 Level 2.

Application Specific Microcontrollers Feature Summary

• Compliant with TCG TPM 2.0 specifications and SP800-193 standards
• Integrated Arm SecurCore SC300 core with flash-based non-volatile memory
• SPI interface supporting up to 33 MHz operation
• Self-recovering firmware loader ensuring continuous functionality during interruptions

Application Specific Microcontrollers Applications

• Embedded computing platforms requiring hardware-rooted trust
• Mobile devices needing secure authentication services
• PC client systems adhering to specific TPM platform specifications

Application Specific Microcontrollers Procurement Notes

Verify the package designation VFQFPN 32 (5x5x1.0 mm) and industrial grade classification against project requirements. Confirm RoHS compliance via Ecopack2 standards. Check current availability status as inventory levels fluctuate. Ensure ordering quantities align with reel or cut tape packaging options provided by distributors.

Application Specific Microcontrollers Selection Notes

Select this component when TCG TPM 2.0 compliance is mandatory for system certification. The extended temperature range option (-40 °C to 105 °C) requires verification of the specific voltage configuration (3.3 V). Evaluate the need for SPI versus I2C interfaces based on host controller capabilities and pin count constraints.

Application Specific Microcontrollers Part Context

This part belongs to the STSAFE-TPM family from STMicroelectronics, designed for standardized security solutions in embedded and mobile applications. It shares architectural similarities with other ST33TPHF series devices but differs in interface type and specific certification revisions. The AHD4 suffix denotes specific packaging and commercial/industrial grade variations within the broader STSAFE portfolio.

Application Specific Microcontrollers Replacement Considerations

Direct substitutes include other ST33TPHF series variants with compatible interfaces. Verify pin compatibility and firmware command set equivalence before swapping. Cross-reference TCG certification levels to ensure regulatory compliance remains intact after replacement.
