The RA2L2 group is the RA Family’s entry-level single-chip microcontroller based on the 48MHz Arm® Cortex®-M23 core and up to 128KB code flash and 16KB SRAM memory. The optimized processing and Renesas' low-power process technology make it the industry's most energy-efficient ultra-low power MCU. The RA2L2 group supports a wide operating voltage range of 1.6V to 5.5V, and it has rich serial communication functions such as I3C, SSI, low power UART, CAN, USB Full-Speed (FS) without crystal, and USB Type-C interface. The RA2L2 provides pin and peripheral compatibility with the RA2L1 group, RA2E1 group, and RA2A1 group and is ideal for battery-operated applications and other systems requiring high performance and low-energy consumption in space-constrained applications.
