Key Technical Specifications
The NPCT750 datasheet outlines a versatile security solution designed for broad compatibility:
Compliance: Implements TCG TPM 2.0 (Rev 1.38/1.59) and is FIPS 140-2 Level 2 and Common Criteria (CC) EAL4+ certified.
Interface: Utilizes an SPI (Serial Peripheral Interface) or I2C, making it easy to connect with minimal interference. The Nuvoton NPCT750 is a single-chip Trusted Platform
Cryptographic Support: Features hardware accelerators for RSA (digital signatures, encryption/decryption) and ECC (Elliptic Curve Cryptography).
Form Factor: Available in multiple package options including QFN32 (3x3mm for IoT), TSSOP28, and UQFN16.
Operating Range: Supports a wide temperature range from 0°C to 70°C (standard) or -40°C to 105°C for industrial applications. User Experience & Reliability
Reviews from retailers like Amazon and Newegg highlight its practicality:
This is the simplest implementation for a regulated 3.3V rail from a 5V or 9V input. Circuit A: Fixed Output (3
Components:
Formula: None needed. Connect VOUT directly output load.
The heart of any datasheet lies in its absolute maximum ratings and recommended operating conditions. For the NPCT750, these tables are non-negotiable. Absolute maximums define the destruction limits—exceed 4.0V on a 3.6V-tolerant I/O, and the chip releases its magic smoke. Operating conditions, meanwhile, guarantee function: a supply voltage of 3.0V to 3.6V, with typical current consumption of 12 mA at 50 MHz. The datasheet might also include timing diagrams for serial buses, showing setup and hold times. If the NPCT750 is a sensor, the datasheet would list offset error, gain error, and nonlinearity—specifications that determine if the device can measure a 1 mV signal amidst 5V of noise.
A subtle but vital inclusion is the typical performance characteristics graphs. These curves (e.g., supply current vs. frequency, output voltage vs. load current) are not guaranteed but are invaluable for predictive design. For the NPCT750, a graph showing ADC effective number of bits (ENOB) versus sampling rate might reveal that 12-bit performance collapses at rates above 100 kSPS—information that never appears in the main tables.
The NPCT750 is widely deployed across various sectors, including:
The NPCT750 is a low-voltage current transformer (CT) manufactured by GE (General Electric), designed for use in electrical power monitoring and metering applications. As a member of the "N" series, this device is engineered to transform high primary currents into standardized low-level secondary currents, making it safe and practical for measurement instruments, protective relays, and energy management systems to read power consumption data.
