Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Renesas Electronics Corporation (Renesas) recently announced the launch of the RA2L2 microcontroller (MCU) product group, taking the lead in supporting the new USB-C Revision 2.4 standard in the industry. This MCU is based on the 48MHz Arm Cortex-M23 processor and has rich functional features, making it an ideal choice for portable devices and personal computers (PCS).

The new USB Type-C cable and connector specification version 2.4 can reduce the voltage detection threshold (0.613V for 1.5A power supply and 1.165V for 3.0A power supply). The RA2L2 MCU is the first in the industry to support this new standard.

The RA2L2 MCU adopts proprietary low-power technology, providing an operating current of 87.5μA/MHz and a software standby current of only 250nA. It also provides an independent working clock for the low-power UART, which can be used to wake up the system when receiving data from Wi-Fi and/or the low-power Bluetooth ® module. Including support for USB-C, these features make the RA2L2 an ideal solution for portable devices such as USB data loggers, charging cases, and barcode scanners.

The new type of MCU not only supports USB-C with CC detection function and up to 15W (5V/3A), as well as USB FS, but also provides LP UART, I3C and CAN interfaces to help designers reduce the number of required components, effectively lower BOM costs, save circuit board space and reduce power consumption.

The RA2L2 MCU is supported by the Renesas Flexible Configuration Software Package (FSP). FSP provides the necessary infrastructure software, including multiple RTOS, BSP, peripheral drivers, middleware, connection and network functions, as well as reference software for building complex AI, motor control and cloud solutions, thereby accelerating the application development speed. It enables customers to integrate their existing code and the selected RTOS with the FSP, providing full flexibility for application development. With the help of FSP, the migration of existing ips between different RA products can be simplified.

Daryl Khoo, Vice President of Embedded Processing Marketing Division at Renesas said: The RA2L2 product group MCU, as our first product that fully supports full-speed USB and USB-Type C connectors, can effectively control the system cost to remain at a low level by reducing external components. At the same time, continuing the low power consumption advantage of Renesas' popular RA2L1 product, these new products demonstrate our strength and commitment to responding quickly to customer needs and providing efficient solutions.
