September 18, 2025 /SemiMedia/ — Renesas Electronics has introduced the RA0L1 microcontroller group, built on the Arm Cortex-M23 core, targeting battery-powered devices, consumer appliances, and industrial controls with low-power and capacitive touch requirements.

The RA0L1 MCUs achieve just 2.9mA in active mode, 0.92mA in sleep mode, and as low as 0.25µA in software standby. An integrated high-speed on-chip oscillator enables rapid wake-up, allowing the devices to cut power consumption by up to 90% compared with conventional solutions.

Designed for cost-sensitive applications, the RA0L1 family supports an operating voltage range of 1.6V to 5.5V, reducing the need for external regulators. It integrates multiple communications interfaces, analog functions, and security features. Packaging options include QFN, LQFP, and LSSOP, with the smallest package measuring 4mm x 4mm.

The devices also bring Renesas’ capacitive touch technology, supporting up to 24 channels with self-capacitance for simplified waterproof design. The solution meets IEC61000 4-3 Level 4 standards, making it suitable for medical and industrial systems requiring high electromagnetic immunity.

RA0L1 MCUs are supported by Renesas’ Flexible Software Package (FSP), providing middleware, connectivity, and security stacks. This enables developers to build applications such as AI, motor control, and cloud connectivity with faster time to market.

The new RA0L1 devices, along with prototyping boards and development kits, are available now through Renesas and its distribution partners. For more information, please visit RA0L1 Group MCUs.
