Nuvoton NPCT750

The is a discrete Trusted Platform Module (TPM) 2.0 IC designed to provide a hardware-based "root of trust" for computing platforms. It is commonly found on 14-1 pin vertical daughtercards used in motherboards from manufacturers like ASUS . Core Specifications

Low-voltage supply domain(s) (e.g., core VDD, I/O VDD)
Multiple serial interfaces: I2C master/slave, SPI, UART
General-purpose I/O (GPIO) with configurable direction and interrupt capability
ADC channels for monitoring voltages/temperatures
Integrated watchdog and reset logic
Power sequencing and supervisory signals (e.g., S5/S3/S0 control lines)
Sleep/low-power modes with wake sources (timer, GPIO, serial activity)
Package options and pin count (list common package(s): e.g., QFN48, TQFP32 — confirm exact package from datasheet)

Nuvoton NPCT750
