Nuvoton Technology's Arm® Cortex®-M23 Core M2003 Series Helps Upgrade from 8-bit to 32-bit, Balancing Performance and System Cost

The 5V operating voltage and high interference immunity, along with the 20-pin small package design, optimize system cost. 

Taiwan Hsinchu－2024/8/21－With continuous advancements in semiconductor technology, the performance of 32-bit microcontrollers has been steadily improving while costs have been decreasing, making them the mainstream choice in the market. The rapid growth in applications such as AIoT, industrial automation, smart homes, energy storage, and automotive electronics has placed higher demands on microcontroller performance. Traditional 8-bit microcontrollers often fall short in various applications, driving the widespread adoption of 32-bit microcontrollers. To address these market challenges, Nuvoton Technology has launched the new M2003 series of 32-bit microcontrollers based on the Arm® Cortex®-M23 core. This series not only features fast computing capabilities and an integrated hardware divider but also supports 5V operating voltage and high interference immunity. The 20-pin small package design meets the market's needs for both performance and optimized system cost. 

The M2003 series adopts the Arm® Cortex®-M23 core and is a 32-bit microcontroller with an operating frequency of up to 24 MHz. It includes a 32-bit hardware multiplier/divider, offers 32 KB of Flash memory, 4 KB of SRAM, and operates within a voltage range of 2.4V to 5.5V, with an operating temperature range of -40°C to 105°C. 

To meet diverse performance design requirements while reducing size and cost, the M2003 series supports 4 sets of 32-bit timers, 1 watchdog timer, a 3-channel enhanced input capture timer, 2 UARTs, 1 I²C, and 1 universal serial control interface (USCI), which can be flexibly configured as UART/SPI/I²C. Additionally, all communication interfaces are equipped with independent FIFO to ensure data integrity during high-speed communication. This series also provides rich analog peripherals, including an 8-channel 12-bit 500 ksps ADC and a 6-channel 16-bit PWM. The series offers small package sizes in TSSOP20 and QFN20 (3 x 3 mm). 

The M2003 series comes equipped with the NuTool - CodeGenerator tool. Developed in-house by Nuvoton, this tool can quickly generate initialization projects and integrates peripheral, pin, and clock configuration functions. Users can easily set system parameters through an intuitive interface, and the generated code is fully compatible with Keil, IAR, and NuEclipse, helping to reduce setup time and improve development efficiency. The M2003 series supports both ISP and IAP upgrade methods, simplifying system and software update processes, allowing developers to fully utilize the numerous features of the M2003 series. Combined with the NuMaker-M2003FC development board and Nu-Link debugger, it supports Keil MDK, IAR EWARM, and NuEclipse IDE, and uses the GNU GCC compiler, providing a complete development ecosystem.
