Npct750 Datasheet //top\\ Today

Nuvoton NPCT750 is a highly secure Trusted Platform Module (TPM) 2.0

Key features

  • Core: 32-bit ARM Cortex-M0+ (single core) running up to ~48 MHz (typical for M0+ class).
  • Memory: On-chip flash (commonly 32–128 KB range) and SRAM (commonly 4–16 KB); exact sizes vary by NPCT750 variant.
  • Peripherals: Multiple UART/USART, I2C, SPI, PWM, ADC (10–12 bit), and timer/counter modules for real-time tasks.
  • Low-power modes: Several sleep and deep-sleep modes to minimize battery drain in portable designs.
  • Security: Basic hardware security features (secure boot, flash protection, option bytes/lock bits); may include cryptographic accelerators on some variants.
  • Package options: Small-outline packages (QFN, LQFP) suitable for compact PCBs.
  • Operating voltage: Typical single-supply range around 1.8–3.6 V.
  • Temp range: Industrial and commercial options (e.g., –40 °C to +85 °C for industrial).
  • Dropout Voltage: It is not a "super low dropout" regulator compared to some modern DC-DC converters. You need about 200mV to 600mV headroom depending on load. If you are trying to step 3.3V down to 3.0V at high current, this might run out of headroom.
  • Thermal Constraints: Like all linear regulators, it dissipates power as heat. The datasheet highlights the QFN package, which has a thermal pad. If you are dropping 12V down to 3.3V at 500mA, you will need a copper pour or a heatsink. The datasheet thermal resistance specs (θJA) are optimistic if you don't follow the layout guidelines.
  • Bypass Pin: You must pay attention to the NR/SS (Noise Reduction/Soft Start) pin. The datasheet specifies a capacitor here to filter internal reference noise. Omitting this degrades performance significantly.

Overview of NPCT750

Security Certifications: Common Criteria EAL 4+ and FIPS 140-2 Level 2. Interface: Serial Peripheral Interface (SPI). Supply Voltage ( VCCcap V sub cap C cap C end-sub ): 3.3V. Nuvoton NPCT750 is a highly secure Trusted Platform

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.

Secure Boot: It ensures that only signed, trusted firmware is executed during the boot process.
