The NuMicro® CM2003CF3AE 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 KB Flash Memory, 4 KB SRAM, 2.4V ~ 5.5V operating voltage, and -40°C ~ +105°C operating temperature.

Enhanced IP compared to NuMicro 1T-8051 series

The CM2003CF3AE 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 CM2003CF3AE also provides rich analog peripherals including 8 single-end analog input channels of 500 ksps 12-bit ADC and 6-channel 16-bit PWM. The peripherals integrated into the CM2003CF3AE offer enhanced functionality compared to the NuMicro 1T-8051 series products.

Pin Compatible with NuMicro 1T-8051 series

The CM2003CF3AE with multiple function pins is fully compatible and seamlessly aligned with the Nuvoton CM1003 series. This includes compatibility with specific part numbers such as  CM1003BF2AE, CM1003BF3AE, CM1003CF2AE, and CM1003CF3AE .
