Fujitsu Launches the FWM7BLZ23: a New Bluetooth low energy module with Large Memory of 1024KB Flush and 256KB RAM

PublishTime： 2023-04-27 Article Source：Fujitsu News

Fujitsu Components - a leading IoT solutions company - has launched the FWM7BLZ23 Low Energy Bluetooth Module.

Featuring extended memory, the FWM7BLZ23 Bluetooth low energy 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.

Applications

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 the full capability of Wirepas Mesh and enable the use of Matter.

What is ‘Wirepas Mesh’?

Wirepas Mesh is a wireless mesh network protocol for 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 decentralized mesh network solution, it features high scalability and offers advantages such as self-healing and low to no interference.

What is ‘Matter'?

The matter is an open standard for smart home technology from the Connectivity Standards Alliance, an organization 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. Using 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 cooperate with a large line-up of other Wirepas-enabled devices from several different suppliers.

Pricing and availability

The Fujitsu FWM7BLZ23 Bluetooth low-energy module is available from April 25.
