Overview

The RL78/F23 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/F23 can cover prospective market requirements. With its increased CPU performance, high-temperature capability, and enhanced peripheral feature set, RL78/F23 is a perfect fit for various applications.

RL78/F2x products are designed according to ISO 26262 and provide functional safety (FuSa) support 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 off-load complex trigonometric and arithmetic processing.

RL78/F2x MCUs are fully hard- and software upwards compatible to RL78/F1x, enabling software reuse.
