Zilog has been made its Developer Studio II (ZDS II) software available free of charge via download. ZDS II is a Integrated Development Environment that provides a suite of software tools that support development with Zilog's eZ80Acclaim, Z8 Encore!, Z8 Encore! XP, Z8 Encore! MC, and Crimzon product lines. Included in ZDS II are a Microsoft Windows-based project environment, editor, project manager, C compiler, assembler, linker, librarian, simulator, and debugger.

Teachers and professors, for example, can use ZDS II as a tool for developing classes and workshops. Students can download the software to their home machines and/or laptops for class work or projects, whilst design engineers can evaluate the tools and silicon features without the expense of buying a C Compiler upfront. Zilog's software and tools are supported by a technical support desk. The company requests that users register their tool if they require support .
