MCUs with high-resolution analog, over-the-air update support energy conservation

RENESAS ELECTRONICS RA2A2 microcontroller (MCU) Group is based on the Arm Cortex-M23 processor. The low-power devices offer a 24-bit Sigma-Delta analog-to-digital converter (SDADC), and an dual-bank code flash and bank swap function that make it easy to implement firmware over-the-air (FOTA) updates for smart energy management, building automation, medical devices, consumer electronics and other IoT applications. Devices provide multiple power structures and voltage detection hardware to realize energy-efficient, ultra-low power operation as low as 100µA/MHz in active mode and 0.40µA in software standby mode. An independent power supply real-time clock extends battery life for applications requiring long lifetime management in extreme conditions. MCUs also deliver AES hardware acceleration, a high-precision (±1.0%), high-speed on-chip oscillator, a temperature sensor, and a wide operating voltage range from 1.6V to 5.5V.
