FEATURES

The NuMicro® M2354 Series is a TrustZone® for Arm®v8-M architecture empowered microcontroller series focusing on IoT Security based on Arm® Cortex®-M23 CPU core technology. It runs up to 96 MHz with 1024 Kbytes embedded Flash memory and 256 Kbytes SRAM, supporting Flash in dual-bank mode, secure firmware OTA (Over-The-Air) update, ultra-low power consumption in normal run with 89.3 uA/MHz in LDO mode, 39.6 uA/MHz in DC-DC mode and an 8x40 COM/SEG LCD driver inside. Besides the fundamental microcontroller security features, it further enhances the chip-level security in covering side-channel attacks mitigation to crypto hardware engine, fault injection mitigation for operating voltage and clock as well as active shield to cryptographic key storage. The series supports power supply voltage from 1.7V ~ 3.6V in operating temperature range from -40°C to 105°C, and is equipped with both LDO and DC-DC power supply functionalities. The M2354 Series is quite competitive for those devices that need more secure, fast computing and low power in the IoT market.
