Renesas RA4W1 32 bit Microcontroller (MCU) Family for Bluetooth 5.0

August 30, 2020 by Future Electronics

The Renesas RA4W1 microcontroller group is the first 48MHz Bluetooth® Low Energy (BLE) 5.0 compliant single chip MCU.

Compliant with 2Mbit High-Throughput (HT) and Long Range support, the RA4 product series is perfect for IoT applications that require a high-performance Arm® Cortex® M4 core at a very attractive price point.

 

 

The Renesas RA4W1 series is built on a highly efficient 40nm process and is supported by an open and flexible ecosystem concept called Flexible Software Package (FSP), which uses the FreeRTOS as a base. The RA4W1 32 bit microcontroller is geared towards IoT applications requiring security, large embedded RAM and low power consumption.

About the RA4 Series by Renesas

The RA4 Series bridges the needs for reasonable low power with the demand for connectivity and performance. These Renesas MCUs deliver up to 48MHz of CPU performance using an Arm® Cortex®-M4 core with up to 256kB of embedded flash memory. The RA4 series offers a wide set of peripherals, including USB, CAN, ADC, capacitive touch, a segment LCD controller, and additional security IP integration, making it suitable for industrial equipment, home appliances, office equipment, healthcare products, and meters.
