The Nu-Link ICP Programmer is a versatile and reliable in-circuit tool from Nuvoton, designed for both development and production of NuMicro ARM and 8051-based microcontrollers. Acting as a debugger, emulator, and programmer, it supports online and offline firmware programming, reducing your dependence on a connected PC during mass-production. Through its SWD interface and USB connectivity, it provides seamless integration with popular IDEs like Keil, IAR, and CoIDE. The device includes status LEDs to show operation states, and a dedicated offline programming button, enabling you to trigger firmware loading stored inside the tool itself. With unlimited flash breakpoints, memory read/write capabilities, terminal emulation, and serial debug output, the Nu-Link enables efficient debugging and testing. Its plug-and-play USB HID design means no driver hassle, while firmware updates can be carried out automatically, ensuring you always run the latest version. Features: Supports Keil, IAR, CoIDE, and other major IDEs. SWD-based ICP (In-Circuit Programming) for direct programming without removing the chip. Offline programming capability via built-in SPI flash, suitable for mass production. Unlimited flash breakpoints (both in ROM and RAM) for powerful debugging. Memory read/write, terminal emulation, and serial debug output during runtime. USB HID interface — plug-and-play, no driver installation required. Automatic firmware updates for seamless tool maintenance. Status LEDs and a dedicated offline-programming button for intuitive control. Package Includes: 1 x Nu-Link Red Upgrade – Standard Programmer and Debugger for Nuvoton ARM/511 x USB Cable1 x Flat Rebbon Cable5 x Jumper Wire
