M463 CAN FD/USB HS Series

M463 CAN FD USB HS Series

The NuMicro M463 CAN-FD/USB HS series is a 32-bit microcontroller based on Arm Cortex-M4F core, with DSP instruction set and single-precision floating-point unit (FPU), -40°C to 125°C wide operating temperature, targeted for IoT, Industrial, and consumer applications. The M463 CAN-FD/USB series runs up to 200 MHz and features 1.7V to 3.6V wide operating voltage, a variety of packages choice, and excellent high immunity characteristics by ESD HBM 2 KV and EFT 4.4 KV.

As the new smart function added on home appliances, the M463 CAN-FD/USB HS series provides up to 256 KB Flash memory for code storage and 128 KB SRAM for run time operation. Additionally, in response to the code security requirements, the M463 CAN-FD/USB HS series supports Execute-Only Memory (XOM) function to protect confidential program code information from stealing in the run-time. In order to reduce the data access overhead of CPU core to peripherals, 1 set 16 channels of peripheral direct memory access (PDMA) is provided.

The M463 CAN-FD/USB HS series supports plenty of peripherals, including hardware crypto engine, key store, true random number generator (TRNG), 2 sets of CAN FD, USB HS OTG, up to 24 channels of 16-bit PWM, 8 sets of UART, 4 sets of SPI/I2S, 2 set of Quad-SPI, 5 sets of I²C, and a real-time clock (RTC).

The M463 CAN-FD/USB HS 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-M463GC 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.
