RA4W1

48MHz Bluetooth® 5.0 Low Energy Single Chip MCU from RA4 Series

Overview

The Renesas RA4W1 is the first Bluetooth® 5.0 Low Energy 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 base. RA4W1 is geared towards IoT application requiring Security, large embedded RAM and low power consumption.
