The NuMicro® M433 CAN/USB FS series is a high performance, low power microcontroller powered by the Arm® Cortex®-M4F core with DSP instruction and single-precision floating-point unit (FPU) extension. The NuMicro® M433 CAN/USB FS series runs at speeds up to 144 MHz, and the power consumption in the deep power-down mode drops to 350 nA, offering excellent energy efficiency tailored for IoT, industrial, and consumer applications.

The NuMicro® M433 CAN/USB FS series supports operating voltage from 1.8V to 3.6V, and temperature from - 40℃ to 105℃. It provides up to 128 KB Flash memory for code storage and 64 KB SRAM for run time operation. In order to reduce the data access overhead of CPU core to peripherals, 1 set of 9-channel peripheral direct memory access (PDMA) is provided.

The M433 CAN/USB FS series supports plenty of peripherals, including 2 sets of CAN, USB FS OTG, up to 18 channels of 16-bit PWM, 4 sets of UART, 2 sets of SPI/I²S, 1 set of Quad-SPI, 2 sets of I²C, 1 set QEI and 1 set ECAP.

The M433 CAN/USB FS series also provides rich analog peripherals including 2 sets of analog comparators, up to 16 channels of 12-bit SAR ADC.

For the development, Nuvoton provides the NuMaker-M433SE evaluation board, and Nuvoton Nu-Link debugger. The 3rd Party IDE such as Keil MDK, IAR EWARM, Eclippse IDE with GNU GCC compilers are also supported.

The NuMicro M433 CAN/USB FS series supports two package choices.

• LQFP48: Body Size 7 mm x 7 mm, Load Pitch 0.5 mm
• LQFP64: Body Size 7 mm x 7 mm, Load Pitch 0.4 mm
