Overview

Description

The RL78/F24 next-generation super low-power automotive microcontrollers are ideal for realizing future highly reliable smart actuators and sensors, as well as low-end body ECUs. As an innovative prolongation of the known RL78/F1x MCUs, the RL78/F24 can cover prospective market requirements. With its increased CPU performance, high-temperature capability, and enhanced peripheral feature set, the RL78/F24 is a perfect fit for various applications.

RL78/F2x products are designed according to ISO 26262 and support functional safety (FuSa) up to ASIL B. They support up to the EVITA-Light security standard or more. An AES crypto module can handle key lengths of up to 256 bits and supports secure boot and authentication. To further boost the calculation performance for BLDC (FOC) motor control and DC/DC control systems, RL78/F2x is equipped with the unique application accelerator IP to offload complex trigonometric and arithmetic processing.

To respond to the new E/E automotive architecture trend, the RL78/F24 is equipped with a CAN FD interface. RL78/F2x MCUs are fully hardware and software compatible with RL78/F1x, enabling software reuse.

RL78/F24 Motor Control IP BlockSet

We are developing a Simulink model of the peripheral functions mounted in the target device.

Target peripherals:
  • Timer RDe (TRD)
  • 12-bit A/D Convertoer (AD)
  • Application Accelerator Unit (AAU)

Provide simulation blocks that reproduce hardware for motor/inverter control with high accrracy.

By combining this lockset and user model, it is possible to examine and check the operation an actual system on the model.
