NuMaker-PFM-NUC472

The NuMaker Platform is an Internet of Things (IoT) application focused platform specially developed by Nuvoton. It supports ARM mbed OS 5.0 as well as Arduino interface, and is ideal for arrays of IoT application development for prototype development designs with sensors and wireless modules.

The NuMaker-PFM-NUC472 is also equipped with plenty of peripheral devices, such as timers, watchdog timers, RTC, PDMA, EBI, UART, smart card interface, SD host, SPI, I²C, I²S, PWM, GPIO, LIN, CAN, PS/2, 12-bit ADC, analog comparator, operational amplifier, temperature sensor, low voltage reset controller and brown-out detector.

The NuMaker-PFM-NUC472 also provides Ethernet 10/100 MAC with MII and RMII interface, USB 2.0 FS device/host/OTG, USB 2.0 HS device and security functions such as tamper detection, symmetric cryptographic accelerator and secure Hash function accelerator.

The NuMaker-PFM-NUC472 has been designed by Nuvoton in collaboration with mbed for prototyping all sorts of devices, especially those requiring the size and excellent price performance ratio offered by Cortex-M4®. It is packaged as a development board with connectors to break out to strip board and breadboard.
