Renesas Electronics Announces New RA MCU Portfolio in Ultra-Small Package Enables Ultra-Low Power Consumption and Innovative Peripheral Functions

TOKYO, Japan, October 13, 2021 – Renesas Electronics Group (TSE: 6723), a global supplier of semiconductor solutions, today announced the launch of a new product group, the RA2E2, for its 32-bit RA microcontroller (MCU) product family. This series of products is based on the Arm® Cortex®-M23 core, featuring low power consumption and peripherals suitable for IoT terminal applications. wafer-level chip package) to build a unique combination of performance. The new 48MHz RA2E2 product group shortens the product design cycle and can be easily upgraded to other RA products.

Renesas Electronics Announces New RA MCU Portfolio in Ultra-Small Package Enables Ultra-Low Power Consumption and Innovative Peripheral Functions

The launch of the RA2E2 MCU is designed to meet the needs of IoT terminal applications such as wearable devices, medical equipment, home appliances and industrial automation, providing the lowest operating power among similar products in the industry; the power consumption in working mode is only 81uA/MHz, and the software standby current is only 81uA/MHz. 200nA with fast wake-up. The new product supports an extremely wide Ta temperature range of -40 to 125°C, making it suitable for harsh IoT working environments. The RA2E2 MCU supports the I3C bus interface and integrates cost-saving peripheral functions, including an on-chip oscillator with +/-1% accuracy, power-on reset, low-Voltage detector, EEPROM and temperature sensor.

The Renesas RA product family now has more than 160 models operating at frequencies from 48MHz to 200MHz. RA MCUs offer ultra-low power consumption, a wide range of communication connectivity options, and outstanding security features including Arm TrustZone® technology. All RA products are supported by the Renesas Flexible Configuration Package (FSP), which features efficient drivers and middleware to simplify the implementation of communication and security functions. The FSP GUI simplifies and speeds up the development process. FSP can flexibly reuse existing code resources, and easily achieve compatibility and expansion with other RA series products. Developers using the FSP have access to a variety of tools through the rich Arm ecosystem and support through Renesas’ extensive partner network to accelerate time-to-market.

“We are seeing increasing demand for 32-bit MCUs in low-pin IoT end applications,” said Roger Wendelken, senior vice president of the IoT and Infrastructure Business Division at Renesas Electronics. This market demand. The Renesas RA product family now offers a variety of solutions in packages ranging from 16 to 176 pins and performance from 48 to 200MHz, all with FSP support, which enables design IP to be easily and quickly transferred between different products. Convert.”

RA2E2 MCU Product Group

The RA2E2 MCU product lineup includes nine different products, ranging from 16 to 24 pins, configured with 16 to 64KB of flash memory and 8KB of SRAM; in addition, it also includes 2KB of data flash memory, a feature not available in other pin-less products. This product group is also one of the very few MCUs in its class that provides an I3C bus interface, enabling high-speed communication at 4.6Mbps—compared to just 1Mbps for competing products. The RA2E2 product group also has advanced security features with built-in encryption accelerator (AES256/128), true random number generator (TRNG) and storage protection unit.
