Hardware acceleration for keys up to 2048 bits.
The NPCT750 is part of Nuvoton's lineup of highly integrated, low-power microcontrollers designed to meet the requirements of next-generation IoT, industrial, and consumer applications. These devices are usually equipped with ARM Cortex-M series cores, providing a good balance between performance and power efficiency. The NPCT750 specifically is notable for its rich peripherals, including various communication interfaces (like UART, SPI, I2C, and USB), GPIOs, and often featuring cryptographic acceleration for secure data transactions.
The excels in portable applications due to its sub-10µA sleep current, compact 3x3 mm package, wide industrial temperature range, and robust TPM 2.0 feature set . When designing a battery-powered device that requires hardware root of trust—such as a rugged tablet, medical handheld, or secure laptop—the NPCT750 provides the optimal balance between power efficiency and cryptographic performance.
Security silicon frequently receives minor revisions. Always ensure you are reading the document version that matches the exact stepping of the chip on your board.
The Nuvoton is a specialized hardware security chip, specifically a Trusted Platform Module (TPM) 2.0 . While "portable" can refer to mobile power management in some contexts, for this specific part number, it refers to its role as a security anchor in portable computing devices like notebooks and professional tablets .
