RH850 Family Features

1、High Scalability

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

High-performance CPU core

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

Low power consumption

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

Multi-core technology

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.
