MCU with Bluetooth 5.0

The RA microcontroller (MCU) from Renesas are now available with integrated Bluetooth 5.0 Low Energy radio. The single-chip RA4W1 MCU includes a 48 MHz, 32-bit Arm Cortex-M4 core and Bluetooth 5.0 core delivered in a 56-pin QFN package. Together, the RA4W1 MCU and easy-to-use Flexible Software Package (FSP) enables engineers to immediately begin development with Arm ecosystem software and hardware building blocks that work out-of-the-box with RA MCUs.

The RA4W1 MCU makes it easy for embedded designers to develop IoT edge devices for wireless sensor networks, IoT hubs, an add-on to gateways, and an aggregator to IoT cloud applications. The MCU is also well suited for developing safe and secure IoT endpoint devices for Industry 4.0, building automation, metering, healthcare, consumer wearable, and home appliance applications.

While offering an MCU with Bluetooth 5.0 connectivity is not new to Renesas, the addition of the RA4W1 enables our customers to easily adopt Bluetooth 5.0,” said Sakae Ito, Vice President of IoT Platform Business Division at Renesas. “Customers can also take full advantage of the on-chip MCU features, including Secure Crypto Engine to implement strong key management for the ultimate IoT security, and best-in-class output power consumption and sensitivity to achieve a superior link budget for longer range applications.

The RA4W1 MCU includes full Bluetooth 5.0 functions such as 2 Mbps data throughput, all advertising extension functions with maximum advertising length (1650 Byte), periodic advertisements, and channel selection algorithm #2 for applications requiring large amounts of traffic. The RA4W1 also offers low peak power consumption at 3.3mA during receiving and 4.5mA (@0dBm) while transmitting. A sensitivity of -105dBm in 125kbps mode is achieved without additional loss from external components.
