Common Criteria EAL 4+ and FIPS 140-2 Level 2. Interface: Serial Peripheral Interface (SPI). Supply Voltage ( VCCcap V sub cap C cap C end-sub ): 3.3V.
The Nuvoton NPCT750 is a reliable, high-performance TPM 2.0 device that forms the backbone of security for modern systems. Whether for secure boot, data encryption, or platform authentication, its adherence to strict standards makes it an ideal choice.
Master In, Slave Out. Sends data from the TPM back to the host CPU/chipset.
Both are TPM 2.0 devices with the same core functionality. The difference lies in packaging, pinout, or temperature grade. The AADYX variant is used in Tyan’s 11‑pin SPI modules, while AABWX is the standard 48‑pin QFN chip. npct750 datasheet
Uses PCRs (Platform Configuration Registers) to "measure" the state of the system and detect unauthorized changes. Finding the Official Datasheet
CLKRUN# : Clock run signal used in LPC-based power management schemes.
The NPCT750 datasheet highlights its physical defense mechanisms. Because the TPM stores highly sensitive data like BitLocker encryption keys and platform configuration registers (PCRs), the physical chip is built to resist tampering. Security Defenses Common Criteria EAL 4+ and FIPS 140-2 Level 2

The is a popular SKU in this series. It is frequently sourced through major distributors like DigiKey , providing a trusted platform module solution for manufacturers needing to implement TPM 2.0 functionality. Manufacturer: Nuvoton Technology Corporation. Function: Trusted Platform Module (TPM).
When deployed on desktop motherboards via a standard 14-1 pin breakout header, the chip maps across the following hardware lanes: Pin Number Signal Name Description SPI Clock input driven by the host controller 2 Power and Signal Ground reference 3 Chip Select (Active Low) activation lane 4 Master In Slave Out data lane 5 Master Out Slave In data lane 6 Primary VCC power supply voltage input 7 Hardware Reset pin (Active Low) 14 Blank/Missing index pin to prevent incorrect orientation 3. Cryptographic Capabilities & Algorithms NPCT7xx TPM 2.0 FIPS 140-2 Security Policy The Nuvoton NPCT750 is a reliable, high-performance TPM 2
Used in IPCs (Industrial PCs) and IoT devices to ensure that the software and firmware running on the hardware are authentic and haven't been tampered with 1.2.4. Advantages of Nuvoton TPM Technology
Certified to FIPS 140-2 Security Level 2 , confirming physical security, defined role-based authentication, and structural integrity.
This article explores the technical parameters, architectural details, and hardware integration steps typically documented across the official Nuvoton Technology Corporation datasheets, security targets, and reference guides. 1. Core Specifications & Certifications
IBM’s Rainier server platform, used in the OpenBMC project, integrates the NPCT750A device on the 13th I²C bus. The device tree inclusion proves that the NPCT750 is fully compatible with the standard tcg,tpm-tis-i2c driver, demonstrating its suitability for large‑scale server deployments.
