Based on the proprietary WriteNow! Technology, the WriteNow! Series of In-System Programmers is a breakthrough in the programming industry. The programmers support a large number of devices (microcontrollers, memories, CPLDs and other programmable devices) from various manufacturers and have a compact size for easy ATE/fixture integration. They work in standalone or connected to a host PC (RS-232, LAN and USB connections are built-in), and are provided with easy-to-use software utilities.
The WriteNow! Series of In-System Programmers can be controlled by a host PC through simple, ASCII strings through a standard terminal interface. On top of that, a powerful user interface is provided which allows to setup and control the instruments through easy, graphical procedures. The WriteNow! Project Generator guides you through the creation and debugging of a programming Project in a few guided steps: device selection, source file creation, board parameter settings, programming flow options, upload and run of the Project.
