Overview
Description
The Renesas RA4W1 is the first Bluetooth® 5.0 Low Energy (LE) fully compliant with 2Mbit High-Throughput (HT) and Long Range support in a single chip MCU of Renesas RA4 product series for IoT applications that require a high-performance Arm® Cortex®-M4 core at a very attractive price point. The RA4W1 is built on a highly efficient low power process and is supported by an open and flexible ecosystem concept, called Flexible Software Package (FSP), using FreeRTOS as a base. The RA4W1 MCU has full function support for Bluetooth 5.0 Low Energy long-range and mesh networking, and provides excellent reception performance. RA4W1 is geared towards IoT applications requiring Security, large embedded RAM and low power consumption.
