Renesas has introduced a new Group within its 32-bit RA Family of microcontrollers (MCUs). The RA2E2 Group, based on the latest Arm® Cortex®-M23 core, offers a unique combination of extremely low power consumption, a set of excellent peripherals targeted at IoT endpoint applications, and space-saving packaging options including a tiny 16-pin WLCSP (Wafer Level Chip Scale Package) device measuring only 1.87 x 1.84 mm. The new 48-MHz RA2E2 Group enables fast design cycles and easy upgrades to other RA Family devices.
The RA2E2 Group MCUs are designed to address the needs of demanding IoT endpoint and similar applications, including wearables, medical devices, appliances and industrial automation. They offer the industry’s lowest operating power in their class, consuming only 81uA/MHz in active mode with software standby current of only 200nA with fast wakeup. The new devices also support an extremely wide temperature range of Ta = -40/+125°C for harsh IoT operating environments. The RA2E2 Group supports an I3C bus interface and integrates cost-saving peripheral functions, including an on-chip oscillator with precision of +/-1%, power on reset and low voltage detector, EEPROM, and a temperature sensor.

The Renesas RA Family includes over 160 parts ranging from 48MHz to 200MHz. The RA Family MCUs offer industry-leading power consumption specifications, a very wide range of communications options, and best-in-class security options, including Arm TrustZone® technology. All RA devices are supported by the Renesas Flexible Software Program (FSP) that includes highly efficient drivers and middleware to ease the implementation of communications and security. The FSP’s GUI simplifies and accelerates the development process. It enables flexible use of legacy code as well as easy compatibility and scalability with other RA Family devices. All these innovations, included in the RA2E2, mean a reduction in development resource/time by using Renesas FSP’s small memory footprint, HAL driver, and peripheral driver, with software scalability. Designers using FSP also have access to the extensive Arm ecosystem, offering a wide range of tools that help speed time-to-market, as well as Renesas’ extensive partner network.
RA2E2 MCU Group
The RA2E2 Group includes nine different devices, spanning from 16-pin to 24-pin packages, and from 16KB to 64KB of flash memory along with 8KB of SRAM. The devices also include 2KB of data flash memory, a feature not seen on other low-pin count devices currently. They are also the only MCUs in their class to offer an I3C bus interface, delivering high-speed communications of 4.6 Mbps while significantly reducing power consumption. The RA2E2 Group delivers leading security features as well, including a cryptography accelerator (AES256/128), a True Random Number Generator (TRNG) and memory protection units. The RA2E2 MCU Group addresses the market demand for 32-bit MCUs in low-pin-count with the right features and performance for IoT endpoint or similar applications.
