Renesas Electronics has announced the expansion of its 32-bit RA Family of microcontrollers (MCUs) with a new Group based on the latest Arm Cortex-M33 core. The new 100-MHz RA4E1 Group has good power consumption balanced with high performance and optimized feature integration. The RA4E1 MCUs are the first Entry-Line Group in the 100-MHz RA4 Series and the group includes four different parts, spanning from 48-pin to 64-pin packages, and from 256kB to 512kB of flash memory along with 128kB of SRAM. These devices are ideal for cost-sensitive applications and other systems requiring an optimal combination of performance and low power consumption.

 

The RA4E1 devices offer the lowest active power consumption in their class, using only 60µA / MHz while executing from Flash at 100MHz and deliver an optimized combination of innovative peripherals, connectivity options, and system cost saving features.
