概览

瑞萨电子 RA4E1 32 位微控制器 (MCU) 产品群使用支持 TrustZone 的高性能 Arm® Cortex®-M33 内核。 RA4E1 采用高效的 40nm 工艺,是 RA 产品家族微控制器的入门级产品,通过开放且灵活的生态系统(灵活配置软件包 (FSP))提供支持。 RA4E1 适用于入门级物联网应用的需求,这些应用通常需要优化的功能和集成的连接性、降低总体系统成本和平衡的功耗与性能。RA4E1提供 100 MHz 的Cortex-M33 内核和尽可能低的运行功耗(从闪存运行 CoreMark® 算法时功耗低至 81µA/MHz)的组合。

  • 支持 TrustZone 的 100MHz Arm Cortex-M33
  • 256kB - 512kB 闪存以及 128kB SRAM
  • 8KB 数据闪存,提供与 EEPROM 类似的数据存储功能
  • 1kB 休眠用 SRAM
  • 可从 48 引脚封装扩展至 64 引脚封装
  • 全速 USB 2.0,支持主机模式和设备模式
  • CAN 2.0B
  • 四线 SPI
  • 串行通信接口(UART、简单 SPI、简单 I2C)
  • 独立SPI/I2C 多主接口
  • 一般用途

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.
