M032SE3AE

Introduction

The NuMicro® M032 series is a collection of 32-bit microcontrollers developed by Nuvoton. They are based on the Arm® Cortex®-M0 CPU and are equipped with a 32-bit hardware multiplier/divider. Particularly, the M032SE3AE variant has been designed for optimal functionality with an operating voltage spanning from 1.8V to 3.6V, and up to 3.6V tolerance for 5V I/O. This product can operate at temperatures ranging from -40 to 105 ℃, with a maximum frequency of 48/72 MHz.

Function & Applications

The M032SE3AE is an indispensable tool for crystal-less USB applications desiring a 1.8V low-voltage connection interface. It leverages a swift 2 MSPS conversion rate 12-bit ADC and comparators, coupled with a 96/144 MHz PWM control of up to 24 channels—all of which enable rapid, precise data conversion for voltage, current, and sensor data. It then facilitates quick response control to the external device. This microcontroller is capable of accommodating an array of peripherals and supports a flexible Universal Serial Control Interface (USCI) that can be set to UART/SPI/I2C as needed. The product is suitable for applications in Mobile LCD Panel Controller (HMI), IoT Sensing Device, Micro Printer, Gaming Keyboard and Mouse, and TWS Charger among others.

Performance Parameters

The M032SE3AE has a Flash size of 32 KB to 512 KB and a SRAM size of 4 KB to 96 KB. It boasts several key features such as an Operating Characteristics, Core, Memory, and Clocks. To boost its functionality, it includes up to 10 sets of UART, 4 sets of SPI, 4 set I2C, and a 1-wire UART interface for master-slave device data communication. It also supports power management and IEC60730 safety specifications among others.

Package Types, Interface & Pin Configuration

This product is available in the packages of LQFP 64, offering compatibility for different part numbers and system design flexibility. The M032SE3AE features a robust set of communication interfaces, such as 2-set of 6 MHz UART interfaces, 1-set of 24 MHz SPI/I2S interface, and 1-set of USCI interfaces that support UART, SPI, and I2C mode among others. Furthermore, it offers External Bus Interface (EBI), supporting 8-/16-bit data with a maximum external address space of 1MB, along with 51 GPIO.

Reliability & Lifespan

The M032SE3AE provides excellent reliability due to its EFT 4.4 kV and ESD HBM 6 kV characteristics. It's designed for high endurance, with features such as a low-powered operating mode and Power-on Reset functionality, ideal for ongoing long-term usage.

Standards & Certifications

Maintaining adherence to international standards, the M032SE3AE supports IEC60730 safety specifications, providing additional confidence in its safe operation.

Application Cases & Reference Designs

M032SE3AE can be effectively utilized in an array of applications such as Laser Distance Meter, Air Detector/Cleaner, Mobile LCD Panel Controller, Micro Printer, and WPC Wireless Charger. Moreover, for development, Nuvoton has provided evaluation boards and a Nu-Link debugger tool. 3rd Party IDE support is also available (Keil MDK, IAR EWARM, Eclippse IDE with GNU GCC compilers).
