FAQ
Q: How is the power consumption?
A: The RA2E1 is an entry-level ultra-low-power MCU with a wide operating voltage of 1.6V to 5.5V, suitable for battery-powered applications. Refer to the datasheet's electrical characteristics section for specific run/standby current values.
Q: What security features are supported?
A: Arm TrustZone security extension, AES hardware-accelerated cryptography, True Random Number Generator (TRNG), Security MPU hardware-enforced isolation, ID Code protection, and immutable memory.
Q: Does it support capacitive touch?
A: Yes. The device integrates Renesas' second-generation Capacitive Touch Sensing Unit (CTSU2) for capacitive touch buttons, sliders, and wheels without an external touch controller.
Q: What is the operating temperature range?
A: -40℃ to +105℃, qualifying it for industrial automation and outdoor equipment applications.
