Renesas Electronics RA4E1 32-Bit Microcontroller Group
Renesas Electronics RA4E1 32-Bit Microcontroller Group combines a high-performance 100MHz Arm® Cortex®-M33 core with ultra-low active power consumption. These MCUs feature up to 512KB Code Flash memory with background operation, 8KB Data Flash memory, and 128KB SRAM with Parity. These highly integrated devices include a wide range of connectivity options, including USB 2.0 Full-Speed, SPI and Quad SPI, I2C, and CAN2.0B. The RA4E1 MCUs also incorporate Arm TrustZone® security and safety features along with a 12-bit A/D Converter (ADC12) and a 12-bit D/A Converter (DAC12).
The RA4E1 MCUs are built on a highly efficient 40nm process and are supported by an open and flexible ecosystem concept, called Flexible Software Package (FSP), including FreeRTOS and Azure RTOS. These devices are suitable for IoT applications requiring many connectivity options, large embedded RAM, 100MHz performance, and low power consumption.
The Renesas Electronics RA4E1 MCUs are offered in scalable QFN-48 and LQFP-64 packages with a -40℃ to +85℃ operating temperature range.
