Npct750 Datasheet Verified //free\\ Review

Nuvoton NPCT750 is a high-security, single-chip Trusted Platform Module (TPM)

2.0 designed to meet the rigorous standards for PC-client platforms, industrial, and automotive security. Verified technical details and security certifications confirm its compliance with the TCG TPM 2.0 specification. Core Technical Specifications The NPCT750 belongs to the Nuvoton SafeKeeper™ family and is frequently used in daughterboard modules like the ASUS TPM-SPI 14-1 pin TPM Standard: Fully compliant with TCG Version 2.0 (Revisions 1.16, 1.38, and 1.59). Host Interface: Primarily uses the Serial Peripheral Interface (SPI) , though the wider NPCT7xx series also supports Pin Configuration: Common module implementations use a Operating Temperature: (Commercial grade). Verified Security Features

The Nuvoton NPCT750 is a Trusted Platform Module (TPM) chip designed to provide hardware-based security for computing platforms. npct750 datasheet verified

A key feature of the NPCT750 is its compliance with the TCG TPM 2.0 standard (Revision 1.38), which includes the following security and interface capabilities:

SPI Interface Support: It is commonly found in modules (like the ASUS TPM-SPI) that use a 14-1 pin SPI (Serial Peripheral Interface) to communicate with the motherboard's chipset.

High-Level Security Certifications: The chip is FIPS 140-2 certified and carries a Common Criteria EAL4+ rating, ensuring it meets rigorous international security standards for cryptographic modules. Checksum Match: The file hash matches the manufacturer’s

Cryptographic Engine: It features a dedicated hardware engine for RSA (up to 2048-bit) and ECC (Elliptic Curve Cryptography), along with support for SHA-1 and SHA-256 hashing algorithms.

Platform Integrity Protection: It supports PCR (Platform Configuration Register) sets that allow the system to verify the integrity of the boot process (Measured Boot). NPCT7xx TPM 2.0 FIPS 140-2 Security Policy

1. Verification Protocol

Before designing or troubleshooting, confirm the "Verified" status. In engineering contexts, "verified" usually means one of three things: Action Item: Ensure the document revision code on

• Checksum Match: The file hash matches the manufacturer’s original release.
• Errata Check: The datasheet includes or has been cross-referenced with the latest errata sheet (fixing known silicon bugs).
• Sample Confirmation: Physical samples have been tested against the document parameters.

Action Item: Ensure the document revision code on the datasheet matches the latest revision listed on the manufacturer's portal.

5. Software & Firmware

• Firmware – Field-updatable via TPM vendor-specific command (TPM2_FieldUpgrade)
• OS support – Windows (10/11, Server), Linux (kernel TPM drivers), UEFI, ChromeOS
• Driver – Uses standard TCG TPM 2.0 stack (no custom driver required)

Key features

• Low-power operation with multiple sleep and wake modes for modern laptops and low-energy devices.
• Integrated keyboard matrix controller and GPIOs for system I/O.
• Hardware-accelerated crypto primitives (e.g., AES, SHA) for secure firmware and verified boot.
• Multiple serial and parallel host interfaces: LPC, SPI, I2C, UART.
• Embedded flash or external flash support for firmware storage and update.
• Watchdog timer, real-time clock (RTC), and power-management timers.
• Hardware reset control, power sequencing, and power-button/lid/presence detection.
• Secure boot and measured boot support with firmware authentication (PKI-based), rollback protection, and firmware integrity checks.
• Temperature and voltage monitoring inputs; ADC channels for sensor integration.
• DMA controller and interrupt controller for responsive peripheral handling.
• Battery-backed RAM/RTC support for state retention.

3. Electrical Characteristics & Timing

This section dictates how the NPCT750 talks to the rest of your system.

• Logic Levels:
  • Check $V_IH$ (Input High Voltage) and $V_IL$ (Input Low Voltage). Ensure your driving microcontroller or FPGA can swing voltages that the NPCT750 recognizes as a valid logic 0 or 1.
• Current Consumption:
  • Look for Quiescent Current ($I_Q$) for sleep/idle modes.
  • Look for Max Operating Current to size your power supply regulator and decoupling capacitors.
• Timing Diagrams:
  • If the NPCT750 uses SPI, I2C, or a parallel bus, verify Setup Times ($t_SU$) and Hold Times ($t_H$). If your clock speed is too fast, the NPCT750 will miss data bits.
