Cortex M0 MCU
Introduction & Functionality & Applications:
The Nuvoton NuMicro M031 series microcontrollers, specifically model number M031TD2AE, are designed to deliver high functionality and performance in a low-voltage operational environment. They embed the Arm Cortex-M0 core with a 32-bit hardware multiplier/divider, making it possible for these microcontrollers to operate at frequencies up to 48 MHz within a broad temperature range from -40℃ to +105℃.
These microcontrollers have been engineered specifically to provide solutions around fast data conversions accompanied by swift response control for external devices. They find significant applications that necessitate a 1.8V low-voltage interface connection. This can be seen in fields such as industrial control and consumer applications, which require precise data conversions of voltage, current, and output from various sensor devices. They're designed for use in applications such as Laser Distance Meters, Air Detectors/Cleaners, Mobile LCD Panel Controllers, Micro Printers, and WPC Wireless Chargers.
NuMicro M031TD2AE offers up to 10 sets of UART, along with 4 sets of SPI and I2C, adding to its functional versatility. The Flash size provided ranges from 16KB to 512KB, and the SRAM size varies from 2KB to 96KB. On-chip features include a 2 MSPS ADC, 96 MHz PWM, 24 MHz SPI, 6 MHz UART. They also ensure power efficiency with power-down modes that support wake-up functions. Additionally, it comes with built-in bandgap voltage value storage, enabling voltage estimation at different temperature ranges.
Package Types, Interface & Pin Configuration:
The M031 series is available in the package - small form factor QFN33. The M031TD2AE specifically comes in a QFN33 (4x4 mm) package. These varying pin-compatible packages facilitate system design alteration and part replacement.
Reliability & Lifespan:
The M031TD2AE promises a robust lifespan with an operating voltage variation between 1.8 to 3.6V while operating within a temperature range of -40℃ to +105℃. These microcontrollers come with power management features integrated with Power-on Reset, Brown-out Detect, and Low Voltage Reset, ensuring their continued performance in varying conditions.
Standards & Certifications:
Nuvoton's M031/M032 series microcontrollers arrive with sundry certifications that make them suitable for industrial applications. They comply with IEC60730 safety specifications, pertinent for M031xI/M031xG Series, making them optimal for their target applications.
Application Cases & Reference Designs:
These 32-bit microcontrollers have been successfully deployed in applications such as Laser Distance Meters, Air Detectors/Cleaners, Mobile LCD Panel Controllers, IoT Sensing Devices, HMI Controller, Micro Printer, Gaming Keyboard and Mouse, and WPC Wireless Chargers. This broad spectrum of applications underscores the versatility and efficiency of the M031TD2AE and, by extension, the M031 series. Nuvoton also provides a series of NuMaker evaluation boards and Nuvoton Nu-Link debugger for developers, facilitating the design process from inception to completion.
