Overview
Description
The RA0E1 group is a basic, simple MCU in the entry line of the RA0 series, offering excellent cost effectiveness and ultra-low power consumption. It delivers up to 32MHz of CPU performance using an Arm® Cortex®-M23 core with up to 64KB of embedded flash memory and a wide supply voltage range from 1.6V to 5.5V. The RA0 series is ideal for cost-sensitive applications such as low power and lower cost for consumer electronics, system control for small appliances, industrial system control, and building automation.

- TAU (16-bit general PWM timer)
- TML32 (32-bit interval timers)
- RTC
- 12-bit A/D converter
- Temperature sensor
- SAU (UART, Simple SPI, Simple I2C)
- UART
- I2C bus
- Random number generator
- Safety functions
- +-1% high accuracy high-speed on-chip oscillator
- Flexible power architecture with fast wake-up
- Best-in class HAL driver code
- Supports Arm ecosystem and Renesas original development tools
