32-bit MCUs integrate peripheral functions in tiny package

24 November 2021 DSP, Micros & Memory

Renesas Electronics recently added a new product group to its 32-bit RA family of microcontrollers (MCUs). The RA2E2 group, based on the latest Arm Cortex-M23 core, offers a combination of extremely low power consumption, a set of 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. These new 48 MHz devices enable fast design cycles and easy upgrades to other RA-family devices.

The RA2E2 MCUs are designed to address the needs of demanding IoT endpoint applications, including wearables, medical devices, appliances and industrial automation. They offer what Renesas claims is the industry’s lowest operating power in their class, consuming only 81 µA/MHz in active mode with software standby current of only 200 nA with fast wakeup.

The new devices also tolerate a wide temperature range of -40°C to +125°C for harsh IoT operating environments. They support an I3C bus interface and integrate cost-saving peripheral functions such as an on-chip oscillator with precision of +/-1%, power-on reset and low-voltage detector, EEPROM and a temperature sensor.
