Smart Home Audio(325)



The NuMicro® M2003XC1AE 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.

Enhanced IP compared to NuMicro 1T 8051 series

The M2003XC1AE 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 M2003XC1AE 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 M2003XC1AE offer enhanced functionality compared to the NuMicro 1T 8051 series products.

Pin Compatible with NuMicro 1T 8051 series

The M2003XC1AE with multiple function pins is fully compatible and seamlessly aligned with the Nuvoton N76E003AQ20, N76S003AQ20, MS51XB9AE, MG51XB9AE, and MG51XC9AE. (see the tables below)
