RH850/C1M-Ax Microcontroller

Renesas RH850/C1M-Ax in-vehicle microcontroller is specialized for traction motor control in hybrid electric vehicles (HEV) and electric vehicles (EV).

Model-Based Development (MBD) Solution for RH850/C1M-Ax 

Renesas provides model-based development software products that use MathWorks MATLAB®, Simulink® and others as MBD solutions for the RH850/C1M-Ax. This product is currently available for purchase in two versions which are Renesas IP Models for MILS and Motor SW Driver Model. 

The Renesas IP Model for MILS is a simulation model that reproduces the motor control timer (TSG3) and enhanced motor control unit (EMU3) installed in RH850/C1M-Ax under the Simulink environment. The register can be set exactly the same as in the actual microcontroller and its behavior can be observed by a PC. 

The Motor SW Driver Model is a simulation model that consists of an IP model, SW driver model and sample application model, providing auto code generation function. Aside from TSG3 and EMU3, A/D converter, R/D converter (RDC3A), and timer option (TAPA) drivers are also prepared, and the parameters of each driver function can be easily set by using physical values of floating point and constant. Furthermore, the C source of the sample application model can be automatically generated by auto code, thus making it possible to be executed immediately on the actual machine. 

These model products are available as paid/free versions.
In case you want to buy the paid version software package, please contact us.
