The NPCT750 is a specialized integrated circuit manufactured by . It is a hardware-based security chip that implements the Trusted Computing Group (TCG) TPM 2.0 specification. Unlike general-purpose microcontrollers, the NPCT750 is architected specifically for security functions, including:
Often integrated into a 14-1 pin keyed header module. Cryptographic Features
In today's digital landscape, hardware-based security is more important than ever. The is a dedicated Trusted Platform Module (TPM) 2.0 chip designed to provide a robust foundation for platform integrity and cryptographic operations. This article serves as a comprehensive guide to understanding the NPCT750, its specifications, and how to effectively use it in your systems. npct750 datasheet
The NPCT750 is not just a storage chip; it performs critical cryptographic operations in a secure, isolated environment. Key features include:
VBAT : Battery back-up power for the internal RTC/monotonic counters (if utilized). SPI_CLK : Serial Clock input from the host chipset. SPI_MISO : Master In Slave Out data line. SPI_MOSI : Master Out Slave In data line. SPI_CS# : Chip Select (active low). System Control Pins:

RSA (up to 2048-bit keys) for digital signatures and encryption.
The NPCT750 is a TPM 2.0 device, compliant with the TCG specification Family “2.0” Rev1.38. It is not backward compatible with TPM 1.2 without software emulation. It is a hardware-based security chip that implements
For new designs, the Infineon SLB 9670 or STMicroelectronics ST33TPM12LPC are recommended, as they are actively manufactured and have current datasheets readily available.
The NPCT750 is frequently found on specialized add-on cards, such as the ASUS TPM-SPI module NewHail TPM modules , which use a 14-1 pin SPI interface to connect directly to motherboards. Common applications include: Windows 11 Readiness
The datasheet is comprehensive and the silicon delivers. It is more expensive than generic LDOs (like the 1117 series), but for precision analog work, the cost is justified by the elimination of "mystery noise" in your signal chain.
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.
