RX23W microcontrollers incorporate security functions that are vital for Bluetooth® 5.0 Low Energy (BLE) and IoT devices, as well as a wealth of peripheral functions such as touch keys, USB and CAN, enabling system control and wireless communication with devices using a single chip. RX23W MCUs have full function support for Bluetooth 5.0 Low Energy long range and mesh networking, and provide excellent reception performance.

In addition, the RX23W lineup includes a module with a built-in antenna and oscillator. It enables the use of many MCU peripheral function pins while having the industry’s smallest footprint for a module. This module has obtained Radio Law (Japan), FCC/ISED (North America), and CE (Europe) certifications, saving users the trouble of designing an RF circuit or obtaining certifications on their own, shortening time to market.
