Renesas Electronics RH850 32-Bit Automotive MCUs

Renesas Electronics RH850 32-Bit Automotive MCUs offer high-performance balanced with a very low power consumption over a wide, scalable range of products. The RH850 MCUs provide rich functional safety and features embedded security needed for advanced automotive applications. The family offers a range of CPU core structures (single, multiple, lock-step, and combination) to support high-performance, high-reliability requirements.

Features

Scalable CPU core, memory, and peripherals allow the reuse of software resources
- Integrated peripheral function IPs and scalability
- General specifications of basic IPs (serial, counter, etc.) have been refined from existing specifications and will continue to retain compatibility in the future
- Specifications of differentiated IPs (engine control, motor control timer, etc.) have evolved to help increase the competitiveness of the user's product
Greatly improved response performance for frequently used interrupt handling
- Batch save/restore of multiple registers
  - Stop currently running the program in an instant
  - Resume from interrupt handling in an instant
- Branch prediction mechanism that predicts the flow of a program using a learning function
- High-speed flash access, read and run the next program in an instant

Thorough low power capabilities contribute to the reduced overall power consumption of automobiles
- Reduced operating power, use of the 40nm process enables finer circuitry and reduced operating power
- Use of low leak transistor reduces leakage power
- Reduced standby power consumption, cut power to circuits that are idle during standby to reduce power consumption further
Multi-core technology; cores performing functional safety, high-speed calculation, and input/output processing can be combined to achieve a high-performance core configuration
High reliability, support functional safety activities compliant with ISO26262
