Cortex M0 MCU
Introduction & Function & Applications
The Nuvoton NuMicro® M032 series, which includes the product M032LC2AE, essentially offers a robust collection of 32-bit microcontrollers, integrating the technological sophistication of the Arm® Cortex®-M0 CPU upgraded with a 32-bit hardware multiplier/divider. These microcontrollers facilitate smooth operation at 1.8V ~ 3.6V voltage, exhibiting 5V I/O tolerance and achieving operational speeds up to 48/72 MHz within a broad temperature spectrum of - 40~105 ℃.
Specially designed to cater to Crystal-less USB applications seeking 1.8V low-voltage interface connections, the M032 series is enhanced with a 12-bit ADC boasting a high-speed 2 MSPS conversion rate, comparators, and an impressive 24-ch 96/144 MHz PWM control. It is optimized for swift and accurate data conversion catering to voltage, current, and sensor parameters and prompt control response to external entities. Among other various peripherals, the M032 series also comprises the Universal Serial Control Interface (USCI), which can comfortably alternate between UART/SPI/I2C, making it suitable for versatile data communication between master and slave devices. The series can be deployed in a wide array of applications, including Mobile LCD Panel Controllers (HMI), IoT Sensing Devices, Micro Printers, Gaming Keyboards, Mice, and TWS Chargers.
These microcontrollers come powered with a Flash size ranging between 32 KB to 512 KB along with an SRAM size from 4 KB to 96 KB. They also house an enhanced crystal-less USB 2.0 full-speed device feature, which makes them significantly beneficial for various USB-related applications.
Package Types, Interface & Pin Configuration
As for the packaging, the supported form factors is LQFP48 with pin-compatibility spanning multiple part numbers for convenient system design and easy part replacements.
Reliability & Lifespan
Balancing the Extreme Field Transient (EFT) and Electrostatic Discharge (ESD) Human Body Model (HBM) at 4.4kV and 6kV respectively, the M032 series offers robust reliability over a wide temperature range from -40℃ to 105℃.
Standards & Certifications
From a standards and certification standpoint, these controllers support IEC60730 safety specifications, thus ensuring the reliability and safety of the devices over their lifespan.
Application Cases & Reference Designs
