Renesas Electronics has announced the new RH850/C1x series of 32-bit microcontrollers (MCUs), designed for motor control in hybrid and electric vehicles.

The new RH850/C1x devices can be used with the RAA270000KFT RH850 family power supply management IC (PMIC), which integrates into one device all the power supply systems required for MCU operation, two external sensor power supply tracks, and a full complement of monitoring and diagnostic functions, reducing the user burden associated with power supply system design.

According to Renesas, today’s higher-performance applications require MCUs with greater processing capabilities for efficient motor control, challenging system designers to reduce costs and increase performance. By integrating hardware peripherals into the MCU, designers can reduce overall system costs and meet performance requirements.

Hybrid and EV systems are now being designed to meet ISO 26262 functional safety standards, driving semiconductor products to incorporate a number of embedded features that allow system designers to meet their safety goals.

Key Features of the RH850/C1H and RH850/C1M MCUs:

• Incorporation of large memory capacities achieved through 40 nm MONOS process technology
• Extensive set of peripheral functions for hybrid/EV motor control
• Single and dual motor control support, which can be selected according to the application structure
• Diverse set of safety functions for functional safety (ISO 26262) support
