ST33HTPH2032AHD1

Application Specific Microcontrollers Overview

The ST33HTPH2032AHD1 is a flash-memory-based Trusted Platform Module (TPM) 2.0 device from the STSAFE-TPM family, manufactured by STMicroelectronics. It integrates an Arm SecurCore SC300 processor and provides hardware security services compliant with TCG TPM Library specifications 2.0 Level 0 Revision 138. The component supports SPI communication at frequencies up to 33 MHz and includes Common Criteria EAL4+ and FIPS 140-2 Level 2 certifications. It operates within a supply voltage range of 1.8 V or 3.3 V and functions across an extended temperature range of −40 °C to +105 °C.

Application Specific Microcontrollers Feature Summary

• Compliant with TCG TPM 2.0 specifications and certified under Common Criteria (EAL4+) and FIPS 140-2 Level 2.
• Integrates an Arm SecurCore SC300 32-bit RISC core with active shield and environmental sensors for fault injection protection.
• Supports cryptographic algorithms including RSA (1024/2048 bits), AES (128/192/256 bits), ECC, and SHA-256.
• Features firmware upgradeability via a persistent Flash-memory loader application.

Application Specific Microcontrollers Applications

• Embedded computing platforms requiring hardware root of trust.
• PC and mobile devices needing secure boot and data storage capabilities.
• Applications requiring compliance with Intel TXT and Microsoft Windows 8.1/10 security standards.

Application Specific Microcontrollers Procurement Notes

Verify that the specific ordering code matches the required package type, as the ST33HTPH2032AHD1 designation corresponds to the VFQFPN32 package variant. Confirm the preloaded firmware version against project requirements, noting that older firmware versions may be classified as NRND. Ensure power supply filtering meets the mandatory capacitor values specified in the integration guidelines.

Application Specific Microcontrollers Selection Notes

Select this model when a VFQFPN32 package is required for the design. Compare against the ST33HTPH2028AHD1 if a TSSOP28 package is preferred instead. Consider the operating voltage constraints: 1.8 V is suitable for the commercial temperature range, while 3.3 V is necessary for the extended temperature range of −40 °C to +105 °C.

Application Specific Microcontrollers Part Context

This component belongs to the ST33TPHF20SPI product family, which offers standardized TPM solutions for embedded and computing applications. The ST33HTPH2032AHD1 specifically denotes the version packaged in a 32-lead very thin fine pitch quad flat pack no-lead (VFQFPN32) format, distinguishing it from the 28-lead TSSOP28 variant.

Application Specific Microcontrollers Replacement Considerations

The ST33HTPH2028AHD1 serves as a direct functional substitute if the TSSOP28 package is acceptable. For designs requiring different firmware revisions, check compatibility with other ST33HTPH2Exx series codes, ensuring the target firmware image is supported by the existing hardware markings.
