True Random Number Generator (TRNG) compliant with SP800-90A.
Fully compliant with the Trusted Computing Group (TCG) Trusted Platform Module Library Specification Family 2.0 (Level 00 Revision 1.38 or later). Cryptographic Engine: RSA engine supporting key sizes up to 2048 bits.
The device features dedicated hardware accelerators for both symmetric and asymmetric cryptographic operations: npct750 datasheet
The NPCT750 is supported by the standard Linux TPM driver stack. The Linux kernel includes a TPM driver that automatically detects and interfaces with TPM 2.0 chips via the SPI bus, using a compatible string like 'nuvoton,npct751','nuvoton,npct750' to identify the device.

To integrate into different host architectures, the NPCT750 series is manufactured with specific interface options. When reading the datasheet, pay close attention to the specific suffix of your part number, as it dictates the communication interface: LPC Interface (Low Pin Count)
Integrating the NPCT750 into a hardware blueprint involves both physical routing and software enablement. The device features dedicated hardware accelerators for both
The physical module (often integrated into add-on cards like the ASUS TPM-SPI adapter) uses a 14-pin form factor with one pin removed as a keying mechanism to prevent incorrect insertion.
The NPCT750 is engineered to perform the following essential security operations:
