Overview

The RA2E1 group is the RA Family’s entry-level single-chip microcontroller based on the 48MHz Arm® Cortex®-M23 core and up to 128KB code flash and 16KB SRAM memory. The optimized processing and Renesas’ low power process technology make it the industry's most energy-efficient ultra-low power MCU. The RA2E1 group supports a wide operating voltage range of 1.6V to 5.5V and a large selection of packages such as LQFP, QFN, LGA, BGA, and WLCSP. The RA2E1 provides pin and peripheral compatibility with the RA2L1 group and is ideal for battery-operated applications and other systems requiring high performance and low-energy consumption in space-constrained applications.

This sample software acquires gas data from the ZMOD4410 and ZMOD4510 gas sensors and calculates the result. In combination with the I2C driver of the FSP, the sample software controls the ZMOD4410 and ZMOD4510 through the I2C in the MCU to measure gases, acquire ADC data, and calculate the acquired result.
