Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Renesas Electronics Corporation today announced the launch of the RA4L1 microcontroller (MCU) product group, which includes 14 new products that integrate ultra-low power consumption, advanced safety features and segment code LCD support. Based on the TrustZone-enabled 80MHz Arm Cortex-M33 processor, the new MCUS deliver industry-leading performance, functionality and energy savings, providing designers with superior solutions for water meters, smart locks, iot sensor applications and more.

The RA4L1 MCU uses proprietary low-power technology with a power consumption of 168μA/MHz in 80MHz operating mode. With all of the SRAM retained, the standby current is only 1.70μA. In addition, the new products are available in ultra-small packages, including a 3.64 x 4.28 mm wafer-scale chip package (WLCSP), to meet the needs of products such as portable printers, digital cameras and smart labels.

The RA4L1 MCU is powered by the Renesas Flexible Configuration Package (FSP). FSP provides all the infrastructure software you need, including multiple RTOS, BSPS, peripheral drivers, middleware, connectivity, networking, and TrustZone support, as well as reference software for building complex AI, motor control, and cloud solutions to speed up application development. It allows customers to integrate their own existing code and selected RTOS with the FSP, creating full flexibility for application development. In addition, FSP simplifies the migration of existing IP between RA6 or RA2 series products.

Daryl Khoo, Vice President of Embedded Processing Marketing Division at Renesas said: "The Renesas RA2L1 MCU product family has achieved significant success in the market since its launch in 2020, meeting the market demand for low-power applications with capacitive touch capabilities. Our customers have been expecting a unique combination of ultra-low power consumption, more powerful CPU performance, segmental LCD support, and advanced security features. In order to meet this demand, we have launched the RA4L1 product group based on the same high efficiency and low power technology, which is also a positive response and commitment to our customers."
