M262ZIAAE

Introduction

The NuMicro® M262ZIAAE from Nuvoton is a powerful and efficient microcontroller designed to meet the requirements of various Internet-of-Things (IoT) applications. As a member of the M261/M262/M263 Series, this device incorporates an Arm® Cortex®-M23 core, maximizing the performance that can be achieved with the Armv8-M architecture, all while maintaining low power consumption.

Functions and Applications

•IoT and Security
The M262ZIAAE is tailored for IoT applications that demand low power usage and robust security features. The variety of power modes, such as Power-down (PD) and Fast Wake-up Power-down (FWPD), ensure efficient resource use, crucial for battery-powered devices. The secure boot function guarantees that the system boots only with trusted software, preventing unauthorized code execution. Furthermore, features like eXecute-Only-Memory (XOM), AES encryption, and unique identifiers bolster the security framework, making it ideal for sensitive applications.

•Rich Peripherals and Interfaces
This MCU boasts a wide array of peripherals and interfaces, such as multiple timer options, Pulse-Width Modulation (PWM) channels, and diverse communication interfaces, which support complex external module integrations and enable versatile deployment in smart homes, industrial automation, electronic payments, and medical devices, among others.

Performance Parameters

Operating at a frequency of up to 64 MHz and equipped with 512 KB of embedded Flash memory and 96 KB of SRAM, the M262ZIAAE offers excellent speed and storage capabilities. The device is engineered to operate within a supply voltage range of 1.8 V to 3.6 V and an extended temperature range of -40 °C to +105 °C.

•Power Efficiency
The MCU shows outstanding power efficiency, with a low operating current of 97 µA/MHz in LDO mode and merely 45 µA/MHz in DC-DC mode. The power-down current goes as low as 2.8 µA in standby mode and less than 2 µA in deep power-down without VBAT.

•Analog and Digital Functions
Included in the MCU are high-performance analog modules like the 12-bit SAR ADC and voltage type DACs, as well as comparators and a temperature sensor. These elements are essential for creating accurate responses to a variety of analog signals.
