Nuvoton Technology Corporation launched new parts of NuMicro® M480 series features dual ADC and the camera interface. The new M483KGCAE2A microcontroller in M480 series is empowered by Arm® Cortex®-M4F with DSP instruction and FPU and runs up to 192 MHz. The M483KGCAE2A microcontroller provides two independent 12-bit, three sets of CAN Bus 2.0B interfaces for robust industrial communication, 5 MSPS ADCs for simultaneous data sampling in motor control applications, and a camera interface with 1-bit luminance calculation for fast image recognition. The new microcontroller also offer two independent high-speed ADCs having up to 24 channels with the quadrature encoder interface (QEI), and up to 16-ch 192 MHz PWM making M483KGCAE2A able to obtain the position feedback from mechanical devices.


The camera interface in M483KGCAE2A supports CCIR656 and CCIR601 video transmission and offers hardware 1-bit luminance calculation to reduce the usage of SRAM. M483KGCAE2A can recognize patterns shown in images using the digital pattern recognition algorithm ideal for applications such as smart water meter, smart electricity meter or license plate number identification. The three sets of CAN Bus 2.0B interfaces in M483KGCAE2A connects up to three same types or different types of CAN devices. The M483KGCAE2A works as an CAN bridge allowing a flexible design of the network topology making it an ideal solution on the charging station or industrial control with robust communication requirement.


The M483KGCAE2A microcontroller offers the security features for system integrity such as Secure Boot to protect the content in flash memory from malicious attack. The Secure Boot will allow verifying the content of flash memory during every boot-up process. Along with this, the M483KGCAE2A also features AES-256 and true random number generator for data encryption/decryption and provides up to 6 tamper detection pins for system protection, 128-bit unique customer identification (UCID), 96-bit chip unique identification (UID).

  • Operating Voltage: 1.8V to 3.6V
  • Operating Temperature: -40°C to 105°C
  • Flash Memory: 256 KB
  • SRAM: 128 KB
  • Operating frequency: 192 MHz
  • Communication Interfaces: USB full-speed OTG, 8 sets of 17 Mbps low-power UART, 1 sets of 3.4 MHz Smart Cards, 3 sets of 3.4 Mbps I²C, 2 set of 48 MB/s Quad-SPI, 3 sets of composite SPI/I²S running up to 96 Mbps or 192 kHz/16-bit I²S, 1 set of 192 kHz/32-bit I²S, and 1 set of SDIO
  • Integrated Analog Circuits: 12-bit 1 MSPS DAC, Two Comparators


For development, the Nuvoton have released NuMaker-M483KG development board supports the image capture interface, two independent 5 MSPS ADCs, and 3 sets of CAN Bus 2.0B interfaces. NuMaker-M483KG supports Arduino module and provides FreeRTOS and Arm® Mbed™ OS with reference program including interface drivers, libraries, and sample programs. Nuvoton also provides versatile hardware and software development tools, such as Nu-Link/Nu-Link-Pro programmer, which supports advanced debug function, PinView software for monitoring pin status in real time, PinConfig software for multi-function pin configuration, sample codes and BSP driver. For debugging, tracing, and analysing the program on development board, the microcontroller supports IDEs such as Keil MDK, IAR EWARM and NuEclipse (GCC).


The new NuMicro M480 series microcontroller comes in several packages including QEN33, LQFP48, LQFP64, and LQFP128 has been put into mass production and samples are available now.
