RA4C1 80 MHz Arm® Cortex®-M33 Based Low-Power MCU

The Renesas RA4C1 32-bit MCU group features the low-power, Arm Cortex-M33 (CM33) core with TrustZone to deliver an ideal balance of low voltage operation, low power consumption, and high performance. The RA4C1 offers operation down to 1.6 V, combined with a low-power standby current of as little as 1.73 µA and a multitude of low-power features enabling the user to dynamically optimize power and performance to their application requirements.

The RA4C1 integrates an advanced security engine offering isolation from improper access from the CPU or a debugger, and offers a 128-bit unique ID, secure key management, and acceleration for Advanced Encryption Standard (AES), Elliptic Curve Cryptography (ECC), and Secure Hash Algorithm (SHA). This security feature secures data from cyberattacks and complies with the latest legislation.

Many low-power features are included in the RA4C1 MCUs, such as segment LCD display drive, real-time clock (RTC) with a high-precision mode, analog-to-digital converter (ADC), and timers, as well as integrated communications interfaces such as CAN FD, I²C, SPI, and low-power UARTs. All these built-in features make the RA4C1 MCUs ideal for metering applications such as power, gas, and water meters, as well as many industrial automation, home appliances, smart home, consumer, and building/home automation applications.

The RA4C1 comes in a range of 64-pin or 100-pin LQFP packages and offers support for operating temperatures of -40°C to +105°C. The RA4C1 MCUs are fully supported by the Renesas Flexible Software Package and a comprehensive set of hardware and software development tools.
