The NuMaker-PFM-M487 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-M487 also provides Ethernet 10/100 MAC with RMII interface, USB 2.0 FS device/host/OTG, USB 2.0 HS device/host/OTG and security functions such as tamper detection, symmetric cryptographic accelerator and secure Hash function accelerator. The NuMaker-PFM-M487 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.

ICE Firmware Update¶
DAP Link Interface Firmware Update
The Nuvoton mbed PFM boards is fitted with an NUC12SRE3DE MCU running the DAPLink interface firmware to provide three main functions over a single physical USB connection.
- USB disk “drag and drop” programming – ideal for fast prototyping or in-field upgradable products.
- Debug interface using the Nu-Link – provides full debug capability with tools like Keil MDK.
- USB serial interface between the host computer and the target.
Currently no update required.
- Set MSG switch (No.4 of ISW1 on ICE) to ON. (It should be default at ON position)
- Download NuMaker ICE firmware file Download
- There is ICE firmware file "NuLink1FW.bin"
- Keep pressing DAP button and connect the USB port to your PC. A Nu_Link drive will be mounted. (Not Mbed drive)
- Copy the "NuLink1FW.bin" to the Nu_Link drive.
- When copy done, disconnect USB.
