Renesas introduced the RA4W1 microcontroller (MCU) with an integrated Bluetooth 5.0 Low Energy radio, which includes a 48 MHz, 32-bit ArmCortex M4 core and Bluetooth 5.0 core delivered in a 56-pin QFN package. The RA4W1 MCU allows the designers to develop safe and secured IoT endpoint devices for Industry 4.0, building automation, metering, healthcare, consumer wearable, and home appliance applications. the MCU is also ideal for developing IoT edge devices for wireless sensor networks, IoT hubs, an add-on to gateways, and an aggregator to IoT cloud applications.
When RA4W1 MCU is combined with the easy to use Flexible Software package (FSP), the engineers can immediately begin development with Arm ecosystem software and hardware building blocks that work out-of-the-box with RA MCUs. The FSP’s open architecture allows customers to re-use their legacy code and combine it with software examples from Renesas and ecosystem partners.
The RA4W1 MCU is designed with field upgradeable 512 KB flash memory, 96 KB SRAM, and connectivity such as USB, CAN, and HMI capacitive touch technology along with the Secure Crypto Engine. The MCU delivers 2 Mbps data throughput and offers superior low peak power consumption at 3.3mA during receiving and 4.5mA (@0dBm) while transmitting, it also has the industry’s best sensitivity of -105dBm in 125kbps mode.
In addition to the Bluetooth 5.0 basic protocol stack package, Renesas provides several API functions that conform to all standard profiles to quickly start and speed up prototype development and evaluation. The innovative development environment of the device allows the simulation development of communication control and system control.
