Nuvoton Technology has launched a new series of highly anti-interference NuMicro® M451. The whole series is based on ARM® Cortex®-M4F. The specifications are based on the industry's wide voltage 2.5V~5.5V power supply and 5V I/O specifications. Reliability, providing industrial operating temperature, minimum -40 ° C, up to 105 ° C, full-temperature full-voltage high-precision internal RC oscillation 22.1184MHz +/- 2%, external 32.768KHz crystal can be automatically calibrated to full temperature error to less than +/- 0.25%, powerful to improve the system's anti-interference ability and fully meet the requirements of communication accuracy specifications, especially suitable for high-performance precision applications such as industrial control, automation systems, safety monitoring, automotive electronics, digital power supplies. Specially designed Voltage Adjustment Interface (VAI), the system can independently adjust the I/O voltage level (1.8V~5.5V), no need to adjust the interface voltage difference for peripheral components and add extra cost, and I/ O input design 5V tolerance capability, greatly improving system integration and stability.
Nuvoton Technology has launched a full range of 33 models, including M451 basic series, M452 USB function series, M453 CAN bus series and M451M series of Cortex®-M0 microcontroller M051. The new Tang technology is complete. The product line can fully meet the needs of Cortex®-M4F at all levels, practice the full-scale assistance of customers, enhance the long-term competitiveness, and fully meet the customer's current development needs and innovative imagination for the future.
NuMicro® M451's full range of ARM® Cortex®-M4F cores with built-in Digital Signal Processor (DSP) and FloaTIng Point Unit (FPU) for high computational efficiency up to 72 MHz Built-in 256/128/72/40K Bytes program memory (Flash ROM), 32/16K Bytes data memory (SRAM), in accordance with InternaTIonal Electrotechnical Commission (IEC) 60730 standard, memory parity check (Parity Check), Hardware Cyclic Redundancy Check (CRC); built-in online upgrade program (Boot ROM) can update the program area (AP Flash ROM) independently, and configure additional independent 4K Bytes online upgrade memory area (In- System Programming Flash ROM), users can develop more flexible and support a variety of peripheral UART, SPI, I2C, CAN and USB online upgrade program code. In addition, the external bus interface (EBI) is supported to make the external memory more flexible. The specifications of the full range of configurations are excellent: 4 sets of 32-bit timers (TImer), dual watchdogs, nested interrupt vector controllers ( Nested Vectored Interrupt Controller (NVIC), integrated rich interface devices, such as Peripheral Direct Memory Access (PDMA), Real Time Clock (RTC), and 5 groups of communication interfaces (UART) support 16 layers of advanced First in First out (FIFO), three sets of four-wire serial bus interface (SPI) support four-wire mode (Quad Mode), two sets of I2C support SMBus and PMBus, two sets of I2S, two groups LIN, CAN bus, ISO-7816-3 interface, full-speed USB OTG, full-speed USB device, 1 MSPS high conversion speed 16-channel 12-bit analog-to-digital converter (ADC), built-in reference voltage (Voltage Reference, Vref) generation circuit Features such as 12-bit digital-to-analog converters (DACs), 2 sets of analog comparators, and temperature sensors, which require developers to have high integration requirements. M451 full range and high resolution 144MHz PWM pulse width modulation, fast motor control timer, resolution "7ns, with drive analog-to-digital converter (ADC), with hardware brake protection and pulse capture, saving microcontroller computing burden The high-order calculations required for efficient motor control are highly advantageous in applications such as industrial automation and motor control. In terms of chip security, the M451 series is designed to protect customers' intellectual property rights. It has designed a wall of iron wall, including Flash security lock, tamper-proof detection pin, 96-bit chip unique serial number (Unique Identification, UID) and 128 unique customer serial number (Unique Customer Identification, UCID), provides multiple protections for development programs.
In terms of development tools, Xintang provides an easy-to-operate and fully functional NuTiny-SDK-M451 software and hardware development environment to facilitate customers to develop new products using the M451 full range in the IAR EWARM and KeilTM RVMDK development environments. Customers can use the exclusive ISP (In System Program), IAP (In Application Program) or ICP (In Circuit Program) provided by Xintang to directly update the system online or offline, increasing the flexibility of production and Design convenience.
At present, the full range of the new Tang M451 has been mass-produced, and the products are packaged in LQFP48 (7mm x 7mm), LQFP64 (10mm x 10mm) and LQFP100 (14mm x 14mm).
Nuvoton Technology will continue to expand its microcontroller product line to provide a competitive, low-power, cost-effective 32-bit microcontroller to meet the needs of our customers.
18V Desktop Switching Power Supply
A 18V Desk-top power supply can be battery charger for your laptop/ CCTV Cameras, or power backup for your bluetooth speaker/stage lighting, or external power source for your massage chair, or charger for your electrombile/electronic vehicle. A desktop power adaptor can be used widely in your life. With the over-current protection/over-load protection/over-voltage protection and short circuit protection, our desktop power supply assured you a perfect safety usage. At the same time, every piece of power adaptor that we produced, was get through 100% full-load burning test for at least 2 hours, and 3000Vac withstanding voltage test for 1 minutes. The conversion rate of our desktop power supplies is 85%, which is much higher than other factories.
