Renesas’ New RA MCU Group Delivers Ultra-Low Power, Innovative Peripheral Functions In Tiny Package

Renesas Electronics Corporation 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 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 (more info).
