According to the datasheet, the chip achieves its processing boundaries through an embedded . This architecture allows the chip to offload computing-heavy math equations from the CPU, such as verifying complex asymmetric keys or digital signatures, without degrading system performance. Hardware Core Architecture & Cryptographic Engine
The NPCT750 is explicitly supported by , a portable TPM 2.0 library from wolfSSL. This library provides additional capabilities beyond the standard TPM 2.0 feature set, leveraging the NPCT750's secure GPIO functionality.
Certified to FIPS 140-2 Security Level 2 , confirming physical security, defined role-based authentication, and structural integrity. npct750 datasheet
The NPCT75x family is and supports both I²C and SPI interfaces. The kernel’s TPM subsystem automatically probes for the chip when the device tree includes the following node:
The system firmware communicates with the NPCT750 using ACPI tables (specifically the TPM2 ACPI table). During the boot sequence, the BIOS measures components (bootloader, kernel, firmware) and hashes them into the NPCT750’s PCRs. According to the datasheet, the chip achieves its
When evaluating the NPCT750 datasheet, several key parameters define its performance, electrical characteristics, and deployment capabilities. Interface Options
