M2003 Series

Nuvoton-M2003 Series

M2003 Series – Your Excellent Choice to Upgrade from 8/16-bit to 32-bit MCU.

The NuMicro® M2003 series 32-bit microcontroller is based on Arm® Cortex®-M23 core with 32-bit hardware multiplier/divider. It runs up to 24 MHz and features 32 Kbytes Flash, 4 Kbytes SRAM, 2.4V to 5.5V operating voltage, and -40°C to 105°C operating temperature.

Knowing that the demand to upgrade from 8/16-bit to 32-bit core increases within all applications, Nuvoton offers M2003 series 32-bit microcontroller to upgrade from 8/16-bit microcontroller easily. To fulfill the upgrade requirement, Nuvoton doesn’t only enhance the core to Arm Cortex-M23 core, but also upgrade the IP and keep the pin compatibility with 8-bit solutions.

Enhanced IP compared to NuMicro 1T 8051 series

The M2003 series provides plenty of peripherals including 4 sets of 32-bit Timers, Watchdog Timers, 3-channel enhanced input capture, up to 2 sets of UART, 1 set of I2C and 1 set of Universal Serial Control Interface (USCI) that can be set as UART/SPI/I2C flexibly. Furthermore, all these communication interfaces have the individual FIFO to ensure the integrity of high-speed communication data. The M2003 series also provides rich analog peripherals including 8 single-end analog input channels of 500 ksps 12-bit ADC and 6 channels of 16-bit PWM. The peripherals integrated into the M2003 series offer enhanced functionality compared to the NuMicro 1T 8051 series products.

Pin Compatible with NuMicro 1T 8051 series

The M2003 series with multiple function pins is fully compatible and seamlessly aligned with the Nuvoton N76E003 series, N76S003 series, MS51 series, and MG51 series. This includes compatibility with specific part numbers such as N76E003AT20, N76E003AQ20, N76S003AT20, N76S003AQ20, MS51FB9AE, MS51XB9AE, MG51FB9AE, MG51FC9AE, MG51XB9AE, and MG51XC9AE.
