Overview
The Renesas RA4E1 group of 32-bit microcontrollers (MCUs) uses the high-performance Arm® Cortex®-M33 core with TrustZone. The RA4E1 is built on a highly efficient 40nm process and is supported by an open and flexible ecosystem concept—the Flexible Software Package (FSP) —and is the perfect entry point into the RA Family of microcontrollers. The RA4E1 is suitable for entry IoT applications requiring value optimized feature and connectivity integration, total system cost reduction and an optimized mixture of high performance with 100 MHz Cortex-M33 Core in combination with lowest active power consumption down to 81µA/MHz running the CoreMark® algorithm from Flash.

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. Related Files: ZMOD4xxx Sample applicationCompiler: GCC IDE: e2 studio |
