June 10, 2025 /SemiMedia/ — Renesas Electronics Corp. has introduced its RA2L2 microcontroller family, featuring ultra‑low power consumption and industry‑first compliance with USB‑C Revision 2.4 – a notable step forward for semiconductor-based peripheral solutions.
Built around a 48 MHz Arm Cortex‑M23 core, the RA2L2 MCUs support the new USB‑C spec’s lower voltage detection thresholds (0.613 V at 1.5 A, 1.165 V at 3 A), enabling precise connector handling in semiconductor peripherals. With active-mode current at just 87.5 µA/MHz and software-standby as low as 250 nA, plus a dedicated low-power UART clock for waking via Wi‑Fi or Bluetooth LE, the RA2L2 targets battery‑powered semiconductor devices such as data loggers, charge cases and barcode readers.
In addition to full-speed USB‑C CC detection up to 5 V/3 A (15 W) and USB‑FS support, the MCU integrates I³C, CAN, LP‑UART, SPI, I²S and a 12‑bit ADC with 17 channels. This rich peripheral set helps reduce component count, board footprint, and system costs in semiconductor-based designs.
The RA2L2 family is supported by Renesas’ Flexible Software Package (FSP), which provides infrastructure for RTOS, BSP, peripheral drivers, middleware, connectivity and cloud, plus reference code for AI, motor control and cloud implementations. FSP enables easy migration of legacy RA‑series IP and supports customers’ preferred real-time OS.
“Our RA2L2 MCUs are the first in our lineup to offer full-speed USB with USB‑C connector support, while maintaining the low‑power and cost benefits of the RA2L1 series,” said Daryl Khoo, VP of Embedded Processing Marketing at Renesas. “These devices reflect our commitment to rapidly delivering semiconductor solutions tailored to customer needs.”
The RA2L2 MCU series is now available, along with evaluation kits and FSP software.For more information, please visit RA2L2 MCUs.
