ST33HTPH2E28AHD0

Application Specific Microcontrollers Overview

The ST33HTPH2E28AHD0 is a Trusted Platform Module (TPM) microcontroller from STMicroelectronics, supporting both TPM 1.2 and TPM 2.0 specifications. It features an integrated SPI interface compliant with TCG standards for secure communication. The device includes non-volatile FLASH memory for key storage and cryptographic operations. It is housed in a 28-TSSOP package with a width of 4.40mm. The component is designed for high-security applications requiring robust authentication and data integrity protection.

Application Specific Microcontrollers Feature Summary

• Supports dual compliance with TPM 1.2 and TPM 2.0 standards for versatile security implementation.
• Integrates a TCG-compliant Serial Peripheral Interface (SPI) for reliable host communication.
• Includes internal FLASH memory to securely store cryptographic keys and platform state information.

Application Specific Microcontrollers Applications

• Desktop and laptop computer platform security
• Server and data center hardware authentication
• IoT device identity and secure boot processes

Application Specific Microcontrollers Procurement Notes

Verify the current lifecycle status before integration, as this component may be designated as Not Recommended for New Designs (NRND). Confirm that the specific package variant matches the PCB footprint requirements. Ensure the design supports the required SPI voltage levels and timing constraints defined in the official datasheet. Check for any recent product change notifications that might affect long-term availability or pin compatibility.

Application Specific Microcontrollers Selection Notes

Select this component when a system requires certified TPM 2.0 functionality alongside legacy TPM 1.2 support. It is suitable for designs needing a dedicated security coprocessor with SPI connectivity rather than I2C or UART interfaces. Consider the 28-TSSOP package size constraints during layout planning. Evaluate the need for external flash if internal storage capacity is insufficient for specific application key loads.

Application Specific Microcontrollers Part Context

This part belongs to the ST33TPHF2ESPI series of security ICs from STMicroelectronics. It is categorized under Security ICs and Authentication ICs. The series focuses on providing hardware-rooted trust for embedded systems. The ST33HTPH2E28AHD0 specifically addresses the market demand for standardized platform security modules in consumer and industrial electronics.

Application Specific Microcontrollers Replacement Considerations

Check for direct substitutes within the ST33TPHF2ESPI family that offer different memory sizes or package options. Verify compatibility with existing firmware drivers when swapping between TPM versions. Consult official distribution channels for updated lifecycle status to avoid obsolescence risks in production runs.
