The NWR-005 Nuvoton is a USB programmer based on the ICP (In-Circuit Programmer) signal interface for the development of the Nuvoton 8051 LPC chip, USB programmer for ISP (In-System Programmer) signal interface for the development of Nuvoton 8051 Standard chips. The NWR-005 is a full-featured programmer with online programming and offline programming. Online programming means that the NWR-005 downloads the firmware of the 8051 LPC series microcontroller to the target chip under the operation of the computer software. Offline programming means that the NWR-005 directly updates the firmware of the 8051 LPC series microcontroller and does not operate via computer software during offline programming. Off-line programming is suitable for mass production; firmware developers do not need to hand over the original code or firmware file to the production line, only need to transfer NWR-005 to mass production.
