Renesas RL78 Low Power 16-Bit MCUs for Automotive

Known for super low power consumption

The Renesas RL78/F1x 16-bit MCUs are AEC-Q100 automotive-qualified and provide super low power consumption. The large MCU portfolio is scalable from 8 to 512KB flash / 0.5 to 32KB RAM, and from 20 to 144-pins (QFN, LQFP, SSOP packages) to provide optimal coverage for a range of application demands.

The RL78 microcontrollers also feature high temperature support up to 150°C, BLDC / FOC motor control, CAN, LIN, UART, CSI, I2C interfaces and hardware / software compatibility across the family. The MCUs are supported by a full library of design tools, documentation and an extensive ecosystem.

The innovative RL78/F1x MCUs are ideal for all kinds of highly reliable automotive actuators and sensors, as well as low-end ECUs in body and instrument cluster areas.

The RL78/F1x portfolio of AEC-Q100 MCUs provides ultra-low power consumption with widely scalable memory and package options to provide optimal coverage for a range of automotive application requirements.
