Renesas RA2L2 – The first low-power MCU with USB-C Revision 2.4 support

Renesas RA2L2 is the world’s first low-power MCU to support the USB-C Revision 2.4 standard with 15W CC detection, USB FS support. It also offers support for CAN Bus, I3C, and low-power UART. The announcement follows other devices from the Renesas RA series, such as the RA2A2 Arm Cortex-M23 MCU introduced in 2024, and the RA4L1 ultra-low-power MCU unveiled earlier this year with just 168 µA/MHz operation, dual-bank flash, and capacitive touch. The RA2L2 Cortex-M23 microcontroller also embeds up to 128KB of code flash, 16KB SRAM, and 4KB data flash for EEPROM-like storage. It supports a wide 1.6V to 5.5V supply voltage and an industrial-grade -40°C to +125°C temperature range. The MCU also integrates a ±1% high-accuracy on-chip oscillator, multiple timers including 16-bit and 32-bit PWM and low-power asynchronous timers, a 12-bit ADC, a real-time clock, and an internal temperature sensor. It’s available in 32- to 64-pin packages and offers […]
