Renesas RA2E1 Microcontroller Group
New MCUs optimized for cost-sensitive and low-power applications
Renesas has launched the RA2E1 group of MCUs, its first entry-line microcontroller in the Renesas RA family. Based on a 48MHz Arm® Cortex®-M23 core, the RA2E1 group MCUs enable designers to build compact, energy-efficient systems at lower cost while minimizing the need for external components. These MCUs open up a cost-effective upgrade path for applications which are based on a 16-bit MCU and which require the extra performance available from a 32-bit product.
The ultra-low power consumption of the RA2E1 makes it suitable for battery-operated consumer products, appliances and sensors. Power consumption is just 100µA/MHz in Active mode and 250nA in Software Standby mode. Wake-up time from low-power mode is less than 5µs.
The need for external components is reduced by the Renesas RA2E1’s wide range of on-chip peripheral functions. These include a ±1.0% high-speed oscillator, a temperature sensor, a 32-bit timer, a 12-bit ADC and multiple power-supply interface ports. The RA2E1 also has an integrated Capacitive Touch Sensing Unit (CTSU2) which requires no external components.
The RA2E1 MCUs are available in various package options with from 25 to 64 pins, and with from 32kbytes to 128kbytes of Flash memory and 16kbytes of SRAM.
The Renesas EK-RA2E1 Development Kit provides all the components needed to evaluate the performance of the RAE21 series microcontrollers (MCUs).
