Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'D0' against official STMicroelectronics documentation to confirm package type and temperature grade, as variations exist within the ST33HTPH2X32 series. Ensure compatibility with system voltage requirements of 1.62 V to 3.6 V before procurement.

Application Specific Microcontrollers Selection Notes

Select this component when a TCG-compliant TPM 2.0 solution with SPI connectivity is required. Compare with the ST33HTPH2X32AHE4 variant if reel packaging or different temperature ranges are needed. Confirm that the SC300 core performance meets the application's cryptographic workload demands.

Application Specific Microcontrollers Part Context

This part belongs to the STSAFE-TPM family, which provides standardized security solutions for embedded and PC applications. The ST33HTPH2X32 series variants share the same core architecture but differ in packaging, supply voltage options, and industrial-grade temperature extensions.

Application Specific Microcontrollers Replacement Considerations

The ST33HTPH2X32AHD4 is a confirmed alternative within the same family offering identical functional specifications. Verify pinout and package dimensions (VFQFPN 32) to ensure mechanical compatibility during substitution.
