Renesas RA4W1 MCU with Bluetooth 5.0

The single-chip RA4W1 from Renesas Electronics is a microcontroller with an integrated Bluetooth 5.0 Low Energy radio. The 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 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 MCU makes it easy for embedded designers to develop safe and secure IoT endpoint devices for Industry 4.0, building automation, metering, health care, consumer wearable and home appliance applications. It is also suitable for developing IoT edge devices for wireless sensor networks, IoT hubs, an add-on to gateways, and an aggregator to IoT cloud applications.

The MCU features field-upgradeable 512 KB flash memory, 96 KB SRAM and connectivity such as USB, CAN and Renesas’s HMI capacitive touch technology. It also includes Renesas’s Secure Crypto Engine supporting users with symmetric encryption and decryption, hash functions, true random number generation (TRNG), and advanced key handling with key generation and MCU-unique key wrapping.

Enabling users to easily adopt Bluetooth 5.0, the product also features good output power consumption and sensitivity, making it useful for longer range applications.
