Renesas introduces new MCU family

Based on an 80MHz Arm Cortex M33 processor with TrustZone support, the new MCUs from Renesas deliver a desirable combination of performance, features and power savings that enable designers to address a myriad of applications, including water meters, smart locks, and IoT sensors.

The RA4L1 MCUs employ proprietary low-power technology that delivers 168 µA/MHz active mode at 80MHz and standby current of just 1.70 µA with all the SRAM retained. They also are available in very small packages including a 3.64 x 4.28mm Wafer-Level Chip-Scale Package (WLCSP), addressing the requirements of products such as portable printers, digital cameras and smart labels.

The RA4L1 MCUs are supported by Renesas’ Flexible Software Package (FSP). The FSP enables faster application development by providing all the infrastructure software needed, including multiple RTOS, BSP, peripheral drivers, middleware, connectivity, networking, and TrustZone support as well as reference software to build complex AI, motor control and Cloud solutions. It enables customers to integrate their own legacy code and choice of RTOS with FSP, thus providing full flexibility in application development. The FSP eases migration of existing IP to and from either RA6 or RA2 Series devices.

“Renesas’ RA2L1 Group MCUs have seen remarkable market success since their launch in 2020, addressing a diverse range of low-power applications requiring capacitive touch. Built on the same low-power technology, the RA4L1 Group is our response to customers who require the unique combination of ultra-low power with better CPU performance, segment LCD support and advanced security,” said Daryl Khoo, Vice President of Embedded Processing Marketing Division, Renesas.
