Built-in logic that locks or exponentially delays authentication if consecutive incorrect authorization values are supplied to TPM entities (such as PINs or passwords). 6. Implementation Reference: UEFI and OS Integration
Nuvoton engineers the NPCT750 with physical counter-measures to achieve Common Criteria (CC) EAL4+ (and higher depending on exact firmware certification) security baselines:

R2 should be between 1kΩ and 10kΩ to minimize noise while avoiding excessive current draw.
The chip is commonly integrated as a discrete component on motherboards, often found in ASUS TPM-SPI modules, industrial systems from manufacturers like AAEON, and various server platforms.
One of the standout features of the NPCT750 is its adherence to stringent security standards. It holds the following key certifications: Try again later
Extracting the maximum PSRR and lowest noise from the NPCT750 depends heavily on PCB layout. The datasheet will emphasize these points:
The SPI traces between the PCH (Platform Controller Hub) and the NPCT750 must be closely matched in length to prevent skew, adhering to standard high-speed digital design constraints.
The Nuvoton NPCT750 datasheet reveals a chip designed for high-assurance environments where security cannot be compromised. Whether you are building a rugged industrial computer or ensuring a fleet of corporate laptops meets modern security standards, the NPCT750 provides the necessary hardware-based "Root of Trust."
