Description

The RL78/F22 next-generation super-low power automotive microcontrollers are ideal for realizing future highly reliable smart actuators and sensors, as well as low-end body electronic control units (ECUs). As an innovative prolongation of the known RL78/F1x MCUs, the RL78/F22 can cover prospective market requirements. With its increased CPU performance, high-temperature capability, and enhanced peripheral feature set, the RL78/F22 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 field-oriented control (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. RL78/F22 is equipped with a capacitive touch sensing unit (CTSU2SLa).

RL78/F2x MCUs are fully hardware and software upward-compatible with RL78/F1x, enabling software reuse.
