Renesas Electronics Introduces New RA MCU Portfolio in Ultra-Small Packages, Enabling Ultra-Low Power Consumption and Innovative Peripheral Functions

     Renesas Electronics Group, a global supplier of semiconductor solutions, announced the launch of a new product group, the RA2E2, for its 32-bit RA microcontroller (MCU) product family. Based on the Arm Cortex-M23 core, this series of products has low power consumption and peripherals suitable for IoT terminal applications. The package includes an ultra-small 16-pin WLCSP (Wafer Level Chip Scale Package) with 1.87mm x 1.84mm. 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.

     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 an 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 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."

     The RA2E2 MCU product group includes nine different products, ranging from 16 to 24 pins, 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, built-in encryption accelerator (AES256/128), true random number generator (TRNG) and storage protection unit.
