Nutoton Low-Power IoT MCU Released

Nuvoton Technology Corporation launches a brand new low-power security M261/M262/M263 series microcontroller designed for IoT applications. It is based on Arm® Cortex®-M23 secure core for Armv8-M architecture, running up to 64 MHz with 512 KB Flash in dual bank mode supporting Over-The-Air (OTA) Firmware update and 96 KB SRAM. Nuvoton provides a rich product portfolio for new generation IoT applications.

The brand new M261/M262/M263 series adopts advanced low power and security technology with high-performance connectivity interface. The power consumption in the normal run is down to 45 μA/MHz in DC-DC mode and it implements a secure boot function and hardware crypto acceleration to achieve the security of IoT device. M261/262/263 series satisfies the IoT applications in both low power and security requirements. For IoT connectivity and sensor, it integrates SDHC 2.0, USB 2.0 FS OTG, CAN Bus 2.0B high-performance communication interface, and a 3.76 MSPS ADC for sensing data from sensor devices to fulfill a variety of application scenarios. Those features make it a great choice for smart home and IoT node device product design.

Low power is the major requirement for the Internet of Things (IoT) applications. NuMicro® M261/M262/M263 series provides multiple power modes for different operating scenarios, integrating RTC with independent VBAT to support low power mode. The power consumption in normal run mode is 97 μA/MHz (LDO mode) and 45 μA/MHz (DC-DC mode). Standby power-down current is down to 2.8 μA and Deep power-down current is less than 2 μA. The low power, low supply voltage, and fast wake-up (9 μs from Fast-wakeup Power-down mode) features make M261/M262/M263 series suitable for battery-powered IoT applications.

NuMicro® M261/ M262 / M263 series consists of three series

  • NuMicro® M261 series – suitable for classic IoT node devices and wireless communication modules applications
  • NuMicro® M262 USB 2.0 FS OTG series – integrating 1 set of USB 2.0 FS OTG interface (crystal-less design), suitable for connecting USB host/device for data transfer

NuMicro® M263 USB/CAN series – integrating 1 set of CAN Bus 2.0B and 1 set of USB 2.0 FS OTG interface (crystal-less design), suitable for industrial and automotive applications requiring CAN Bus for data communication.
