Excessive Safety Integration, Low Energy, and Small Bundle, Offering Price-Efficient RoT
Nuvoton Know-how launched the upgraded NuMicro M2354, tailor-made for purposes resembling server RoT, sensible metropolis, IoT, and sensible metering.
NuMicro M2354 is an Arm TrustZone microcontroller based mostly on the Armv8-M structure and powered by the Arm Cortex-M23 CPU, designed to reinforce IoT safety. It’s appropriate for long-term confidentiality necessities and extremely delicate information safety situations.
The M2354 operates at frequencies as much as 96 MHz, provides a large working voltage vary of 1.7V to three.6V, and a broad working temperature vary of -40°C to +105°C. The ability consumption is 89.3 μA/MHz in LDO mode and 39.6 μA/MHz in DC-DC mode. The Standby Energy-down mode consumes lower than 2 µA, and the Deep Energy-down mode with out VBAT consumes lower than 0.1 µA, successfully extending the gadget’s battery life and assembly the wants of long-term IoT operation.
For Safe FOTA, the M2354 has built-in dual-bank Flash Reminiscence of as much as 1024 KB and 256 KB of SRAM. Along with supporting eXecute-Solely-Reminiscence (XOM) to forestall code theft, it additionally integrates a cryptographic {hardware} accelerator that helps FIPS PUB 197/180/180-2/180-4 and NIST SP 800-38A, in addition to a {hardware} key retailer to guard in opposition to side-channel and fault injection assaults. When it comes to safe boot mechanism, the upgraded M2354 helps the Root of Belief structure based mostly on DICE, applied in Masks ROM, and helps ECDSA P-521. This function robotically generates a singular gadget id and establishes a sequence of belief throughout boot, successfully verifying firmware model and stopping firmware rollback and tampering assaults. Moreover, M2354 is compliant with PSA Stage 3 and SESIP Stage 3 safety certifications, which meet the calls for of the EU’s Cyber Resilience Act (CRA).
M2354 helps a variety of peripherals, together with CAN, USB 2.0 full-speed OTG, PWM, UART, SPI/I2S, Quad-SPI, I²C, and RTC.
M2354 additionally integrates a number of analog parts, together with analog comparators, ADC, and DAC.
The package deal choices embrace LQFP-48, LQFP-64, and LQFP-128. The upgraded M2354 additionally provides a compact WLCSP49 package deal. With help of the SPDM (Safety Protocol and Information Mannequin) safe communication protocol, the upgraded M2354 is well-suited for Root of Belief purposes in server motherboards and daughterboards.
