80MHz Arm Cortex-M33 Based Low Power MCU with TrustZone, Segment LCD Controller and Advanced Security

The Renesas RA4L1 MCU group features low-power, 32-bit microcontrollers (MCUs) based on the Arm® Cortex®-M33 (CM33) core with TrustZone®, delivering an ideal balance of low voltage operation, low power consumption, and high performance. The RA4L1 offers operation down to 1.6V combined with a low-power standby current of as little as 1.65µA and a multitude of low-power features enabling the user to dynamically optimize power/performance to their application requirements.

These MCUs include low-power features such as segment LCD display drive and an advanced security engine, as well as RTC, ADC, and timers. These MCUs integrate communications interfaces such as CAN FD, USB 2.0 FS without the need of a crystal, I2C/I3C, and low-power UARTs making these devices ideal for many industrial automation, home appliances, smart home, consumer, building/home automation, and medical/healthcare applications.

The RA4L1 comes in a wide variety of standard LQFP and QFN package options as well as a range of space-saving BGA and CSP options and offers support for operating temperatures of -40 °C to 125 °C. The RA4L1 MCUs are fully supported by the Renesas Flexible Software Package and a comprehensive set of hardware and software development tools.
