Offering greater design flexibility and speedier time to market, Fujitsu Components America has released the FWM7BTZ61 series of Bluetooth 5.0 dual-mode wireless modules that are compatible with both Bluetooth Low Energy and legacy Bluetooth Classic BR/EDR, giving designers the flexibility to choose between the two modes with one module.
The fully integrated wireless radio modules are powered by Cypress Semiconductor’s CYW20819 SoC and features Bluetooth Low Energy profile and Bluetooth Classic (BR/EDR) power class 2 capabilities in a single module. It also supports Bluetooth Ver. 5.0’s X2 communication.
The symbol rate and data rate supports both 1 Mbits/s and improved 2 Mbits/s to facilitate communication speed with other Bluetooth Low Energy devices, said Fujitsu. Classic mode supports 1 Mbits/s (BR: basic rate) and 2 Mbits/s and 3 Mbits/s (EDR: Enhanced Data Rate) communication. In addition, the series operates over a wide operating voltage range from 1.71 V to 3.63 V, which enables the devices to work with a variety of system design and power supply conditions.
Two fully certified models, housed in a 17.6 x 10.6 x 1.9-mm package, are available. One model contains the Serial Port Profile (SPP), a common profile for serial communication applications, for Bluetooth Classic, and the GATT profile for Bluetooth Low Energy, which enables all Bluetooth communications with other modules through the GATT layer by using a simple text command via UART.
The second model replaces the GATT Direct Access profile with Fujitsu Components’ unique embedded firmware, which enables simple text-based commands via UART to control all Bluetooth commands and parameters and simplifies a customer’s firmware development, said the company.
This product can also be connected to the Apple Authentication 3.0 Coprocessor (“Auth. 3.0 CP”) to send and receive data with application software on iOS devices. The Auth. 3.0 CP chip must be implemented on the customer’s equipment.
Limited samples are available now and orders will be accepted in January 2021. Contact sales support for more information and pricing.
