Overview

The R9A02G0214CNH#UA0 is a 32-bit RISC-V microcontroller from Renesas based on the RV32I core architecture running at 48MHz. It integrates 128KB of Flash, 16KB of SRAM, and 4KB of EEPROM, specifically designed for low-power operation and high reliability in embedded systems. This MCU includes specialized hardware features like a True Random Number Generator (TRNG) and an Event Link Controller (ELC) to offload the CPU.

Why Choose This Part

This RISC-V implementation offers a high performance-to-power ratio with a run current of 7.80mA at 48MHz and comprehensive safety features like clock frequency accuracy measurement (CAC) and register write protection. It provides a robust peripheral set including a Data Transfer Controller (DTC) and multiple serial interfaces in a space-saving 32-pin HWQFN package.

Applications

Battery-Powered IoT Sensors
Ideal for remote monitoring nodes requiring low standby current and efficient processing of sensor data using the 12-bit ADC and ELC.
Industrial Safety Monitoring
Utilizes the built-in SRAM parity/ECC, CRC calculator, and illegal memory access detection to meet high reliability and functional safety requirements.
Consumer Wearables
The small 5x5mm HWQFN package and low power consumption make it suitable for compact, energy-efficient personal electronics.
