Fujitsu launches the FWM7BLZ23: a new Bluetooth low energy module with extended memory (EMEA)

The FWM7BLZ23 Low Energy Bluetooth Module offers a one-to-one replacement for existing Fujitsu BLZ20 modules while boosting memory for more usage options

Hoofddorp, The Netherlands, April 25, 2023 – Fujitsu Components - a leading IoT solutions company - has launched the FWM7BLZ23 Low Energy Bluetooth Module.

Featuring extended memory, the FWM7BLZ23 module offers a one-to-one replacement for the existing Fujitsu BLZ20 modules but boasts a larger memory to expand the options for usage.

The FWM7BLZ23 Low Energy Bluetooth Module has been developed for use in various remote and app controlled electronic products such as smart lock systems, mobile printers, water heaters, wearable devices and various other wireless devices .

Advantages of the FWM7BLZ23 module

The main advantage of the FWM7BLZ23 Low Energy Bluetooth Module is its large memory of 1024KB Flush and 256KB RAM, which makes it ideal for powering more complex programs and software. This, coupled with its high-performance CPU and ability to be a one-to-one replacement option makes it an ideal option for those wanting to upgrade existing modules.

What’s more, the module’s longer-range capability based on +8dBm radio power, means making the distance between the controlling device – be it a mobile phone, tablet or desktop -- less decisive, making it more intuitive and user friendly.


Supporting Bluetooth Specification Version 5.3, the FWM7BLZ23 Low Energy Bluetooth Module’s hardware encoding system supports 125Kbps BLE LR mode, which enables it to bring out full capability of Wirepas Mesh and enabling the use of Matter.

What is ‘Wirepas Mesh’?

Wirepas Mesh is a wireless mesh network protocol designed for the Internet of Things (IoT) applications. It enables devices to communicate with each other through a self-forming and self-healing mesh network, which allows for reliable and scalable connectivity in large-scale IoT deployments. As a 2.4GHz decentralised mesh network solution, it features high scalability and offers advantages such as self-healing and low to no interference.

What is ‘Matter'?

Matter is an open standard for smart home technology from the Connectivity Standards Alliance, an organisation of hundreds of companies creating products for the smart home. It drives the convergence between the major IoT ecosystems to create one easy, reliable, and secure wireless protocol to connect all IoT devices and networks. Through the use of Matter, businesses can ensure their devices work within any Matter-certified ecosystem using a single protocol.

Additionally, Fujitsu offers module customers and additional services by providing the Nordic SDK plus antenna support directly.

Bringing added value

Devices using the Fujitsu modules can easily become Wirepas mesh enabled. Bringing the advantages of the Wirepas Mesh network and allowing the devices to co-operate with a large line-up of other Wirepas enabled devices from several different suppliers.
