RH850 Family Features

1､High Scalability

Scalable CPU core, memory, and peripherals allow 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 been evolved even further to help increase the competitiveness of the customer's product

PWM: Pulse Width Modulation

LVD: Low Voltage Detection

CAN: Control Area Network

LIN: Local Interconnect Network

FlexRay: An in-vehicle network (in-vehicle LAN) standard

2､High Performance

Greatly improved response performance for frequently used interrupt handling

• Batch save/restore of multiple registers
  Stop currently running program in an instant
  Resume from interrupt handling in an instant

• Branch prediction mechanism
  Predict 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 reduced overall power consumption of automobiles

• Reduced operating power
  Use of 40nm process enables finer circuitry and reduced operating power

• Reduced leakage power
  Use of low leak transistor reduces leakage power

• Reduced standby power consumption
  Cut power to circuits that are idle during standby to further reduce power consumption

Low power consumption and high performance are realized using multi-core technology.

• Cores performing functional safety, high-speed calculation, and input/output processing can be combined to achieve a high-performance core configuration.
