Nuvoton Technology has announced a new member of its NuMicro M480 series, the M483KGCAE2A with dual ADCs and a camera interface. The M483KGCAE2A MCU is based on an Arm Cortex-M4F core with DSP instructions and FPU. The device runs up to 192 MHz and provides two independent 12-bit, 5 MSPS ADCs for simultaneous data sampling in motor control applications, a camera interface with 1-bit luminance calculation for fast image recognition and three sets of CAN Bus 2.0B interfaces for robust industrial communication. Along with the MCU, Nuvoton has released its NuMaker-M483KG development board (shown) to support development based on the M483KGCAE2A.
The two independent high-speed ADCs offer up to 24 channels with the quadrature encoder interface (QEI) and up to 16-channels of 192 MHz PWM. The M483KGCAE2A is able to obtain position feedback from mechanical devices, which realize the precise control of 3-phase servo moto. Multiple channels of ADC are also applied on multiple data sensing in power system applications including UPS and PDU. The MCU can meet IEC-60730 requirements for Class B security.
The camera interface supports CCIR656 and CCIR601 video transmission and provides hardware 1-bit luminance calculation to reduce the usage of SRAM. With the digital pattern recognition algorithm, M483KGCAE2A can recognize patterns shown in images. This makes it well suited for smart water meter, smart electricity meter or license plate number identification applications. M483KGCAE2A is equipped with three sets of CAN Bus 2.0B interfaces, the robust vehicle bus standard, connecting up to three of same types or different types of CAN devices. M483KGCAE2A works as a CAN bridge and allows a flexible network topology design.
M483KGCAE2A runs up to 192 MHz, providing 256 KB Flash memory and 128 KB SRAM. The embedded flash memory supports an eXecute-Only Memory (XOM) feature for securing the sensitive data or algorithms. The SRAM supports full or partial content retention in standby mode for reducing the power usage. When running at 192 MHz, the dynamic power consumption can be down to 130 μA/MHz; whereas in power-down mode, the power consumption of RTC with independent VBAT can be less than 500 nA.
In terms of system integrity, M483KGCAE2A support Secure Boot feature to protect the content in flash memory from malicious attack. With the Secure Boot functionality, M483KGCAE2A will verify the content of flash memory during every boot-up process. M483KGCAE2A also supports AES-256 and true random number generator for data encryption/decryption. Furthermore, M483KGCAE2A provides up to 6 tamper detection pins for system protection, 96-bit chip unique identification (UID), and 128-bit unique customer identification (UCID).
M483KGCAE2A supports 1.8 V to 3.6V operating voltage, -40°C to 105°C operating temperature, 5 V-tolerant I/O pins and up to 3 kV ESD. Communication interfaces comprise 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 include 12-bit 1 MSPS DAC and two comparators.
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 emWin, the GUI software library for an embedded system, to easily and quickly develop and design fluent yet high quality human machine interface.
