Asus Tpm-spi Trusted Platform Module (tpm) Chip: Nuvoton Ncpt 750 Tcg
The datasheet details several package formats depending on the target form factor. The most common package for motherboard integration is the low-profile or TSSOP-28 . Essential Pin Descriptions for SPI/LPC Variants
Reduce (VIN-VOUT) or add a heatsink. For large differentials, consider a switching preregulator.
Example: VIN = 12V, VOUT = 5V, IOUT = 500mA → PD = (12-5)*0.5 = 3.5 Watts. npct750 datasheet
Supports high-speed Serial Peripheral Interface (SPI).
The NPCT750 implements the specification, which represents a significant evolution over earlier TPM 1.2 devices:
Typically available in TSSOP (Thin Shrink Small Outline Package) or QFN (Quad Flat No-lead) packages. Asus Tpm-spi Trusted Platform Module (tpm) Chip: Nuvoton
Typically LQFP/TSSOP (depending on specific revision). Applications of the NPCT750
Usually ranges from 28 pins (for LPC variants) to 16 or fewer pins (for SPI/ I2Ccap I squared cap C variants). Electrical and Thermal Characteristics Supply Voltage ( VCCcap V sub cap C cap C end-sub ): Operates on a standard power rail.
The NPCT750 is a part of the Nuvoton NPCT7xx family of TPM devices. It acts as a dedicated microcontroller designed to secure hardware through integrated cryptographic keys. As a TPM 2.0 compliant chip , it enables advanced security functions such as integrity measurement, secure storage, and cryptographic authentication. For large differentials, consider a switching preregulator
If "npct750" refers to a specific obscure transistor, LCD component, or a game item (New California Republic Playable Characters, etc.), please clarify the manufacturer or context so I can provide the specific technical review you need.
Community developers have successfully added the NPCT750 to custom carrier boards for the Raspberry Pi Compute Module 4 (CM4). By writing a custom device tree source (DTS) file with the "nuvoton,npct75x" compatible string, the Linux kernel properly initializes the TPM over SPI, enabling security features on the popular single‑board computer.
