M23 Low-Power

The NuMicro M261/M262/M263 series, developed by Nuvoton, is a family of low-power microcontrollers that run on an Arm Cortex-M23 core with Armv8-M architecture, ideal for Internet of Things (IoT) applications. It operates at a frequency of up to 64 MHz and features 512 KB embedded flash memory in dual bank mode, 96 KB embedded SRAM, a voltage range of 1.8 - 3.6V, and an operating temperature range of -40 to +105°C. One of the key features of this series is its low power consumption, with different power modes available for diverse operating scenarios. It also supports secure boot, a process for verifying software identity and integrity, and integrates several key peripherals such as Secure Digital Host Controllers, IoT node devices, communication interfaces, RTC, Timers, PDMA, and more. The M261 series is suitable for classic IoT node devices, the M262 series for USB host/device data transfer, and the M263 series for industrial and automotive applications requiring CAN Bus for data communication. These microcontrollers are available in different package types, including QFN33, LQFP64, and LQFP128, and come with support for major third-party IDEs such as Keil MDK, IAR EWARM, and NuEclipse IDE with GNU GCC compilers. In summary, the NuMicro M261/M262/M263 series provides a robust solution for IoT applications, combining low power consumption, secure boot and execution environment, and versatile peripheral support to bring a high level of performance and security to smart home, industrial control, smart city, and other IoT devices.
