embOS for RENESAS M32C was developed for and with IAR's compiler and supports all memory models offered by this compiler.
embOS for M32C comes with easy to use start projects for M32C and M16C80 CPUs which may be used with IAR's embedded workbench. Software development with PD308 debugger, KD308(3) ROM-Monitor, CSpy ROM monitor driver and CSpy simulator and other debugging tools like E8a is supported.
