Overview

The Renesas R9A02G0214CNE#UA0 is a 32-bit RISC-V microcontroller operating at up to 48MHz, featuring 128KB of Flash and 16KB of RAM. It integrates essential peripherals like I2C, SPI, and UART/USART, along with advanced features such as DMA, a True Random Number Generator, and robust security functions. This MCU is designed for applications requiring a balance of performance, low power consumption, and security.

Why Choose This Part

Engineers benefit from the Renesas RISC-V core's efficient performance at 48MHz, combined with extensive security features like a True Random Number Generator and memory protection, crucial for secure IoT applications. The array of low-power modes (down to 230uA standby) extends battery life significantly in portable and embedded systems. Its integrated peripherals and compact 48-HWQFN package simplify design and reduce board space.

Applications

IoT End Nodes
Its low-power modes (Software Standby: 230uA, Snooze mode) and integrated connectivity (I2C, SPI, UART) make it suitable for battery-powered IoT devices and sensor nodes requiring extended operational life.
Industrial Sensors
With features like Watchdog Timers (WDT, IWDT), Low Voltage Detection (LVD), and a built-in temperature sensor, this MCU is well-suited for reliable data acquisition and control in industrial sensing applications.
Smart Home Devices
The 48MHz RISC-V core provides ample processing power for smart home applications, while security features such as Flash area protection and illegal memory access detection enhance device integrity.
Wearable Electronics
Its compact 48-HWQFN package, low active current (7.80mA at 48MHz), and various low-power modes support the design of power-sensitive wearable devices.
Motor Control
The integrated PWM peripherals and 42 I/O pins offer sufficient resources for basic motor control tasks in small appliances or robotics.
