Overview

The R9A02G0214CNK#UA0 is a 32-bit RISC-V based microcontroller from Renesas designed for power-sensitive embedded applications. It operates at up to 48MHz and features 128KB of Flash memory along with 16KB of SRAM and 4KB of dedicated EEPROM for data storage.

Why Choose This Part

This MCU offers a modern RISC-V architecture combined with Renesas proprietary power management, achieving as low as 7.80mA typical current at 48MHz. The inclusion of 4KB of EEPROM and safety-centric features like SRAM ECC and Flash area protection makes it more robust than many entry-level 32-bit microcontrollers.

Applications

Battery-Powered Sensors
Leverages low power modes and 1.6mA consumption at 32.768kHz to extend the life of remote sensing nodes.
Industrial Monitoring
Utilizes built-in safety features like SRAM parity/ECC error checks and CRC calculators for reliable operation in industrial environments.
Consumer Electronics
Provides a compact 4x4mm footprint with essential connectivity including I2C, SPI, and UART for space-constrained devices.
