12 H8 Family of Microcontrollers Overview SoftwareRenesas and the many third-party suppliers in theH8 community provide a wide range of hardwareand software tools and other support services.Renesas offers products that cover all stages of thedevelopment of embedded systems that use H8microcontrollers.Renesas’ integrated development environment Evaluation—Low-cost or no-cost Renesas toolsmake it easy to discover the capabilities of H8MCUs and test the problem-solving power of thetools themselves, including the High-performanceEmbedded Workshop (HEW) integrated softwaredevelopment and debugging environment. Afreely downloadable evaluation version of HEWlets you evaluate the ability of the Renesas C/C compiler to generate efficient code, andevaluation boards enable you to immediately testthat code on known working hardware. Inaddition, the Renesas Interactive onlineengineering laboratory lets you use your own PCto get hands-on experience with powerfulsoftware and hardware tools and experimentwith MCUs before purchase. Debugging—When you begin working on thedesign of your system, you can develop code usingthe full, unlimited compiler in exactly the sameHEW environment. To track down bugs, useRenesas’ on-chip and full in-circuit emulators,which have powerful specialized debugginghardware for trapping specific conditions andrecording program activity. Final Programming—Use Renesas’ FlashDevelopment Toolkit, which has an easy-to-useinterface, to program your debugged applicationinto any of the many H8 MCUs that incorporateRenesas’ mature on-chip flash memory technology.All the tools required for developing H8-basedapplications are available from Renesas distributors.These tools have been developed by groups withinthe worldwide Renesas organization, experiencedengineers who have access to the designers of thedevices themselves. Their insight and expertiseensures the best possible tool performance andsupport.The High-performance Embedded Workshop (or HEW) is agraphical development environment for C/C compilertoolchains with an industry-standard look and feel.
