Fujitsu Components America announced the FWM7BTZ61 series of Bluetooth® Ver. 5.0 (dual mode) wireless radio modules 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 FWM7BTZ61 series is 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 signature X2 communication.
The symbol rate and data rate accommodate both 1Mbps and improved 2Mbps to facilitate communication speed with other Bluetooth Low Energy devices. In addition, Classic mode supports 1Mbps (BR: basic rate) and 2 and 3Mbps (EDR: Enhanced Data Rate) communication.
The series also supports a wide range of operating voltages from 1.71V to 3.63V, which enables the mating with various system design and power supply conditions.
To accommodate different design needs, the series portfolio includes two, fully certified models:
One model contains SPP (Serial Port Profile) for Bluetooth Classic, and GATT profile for Bluetooth Low Energy. SPP is the most common profile for serial communication applications, and GATT profile enables all Bluetooth communications with other modules through the GATT layer in the module by using a simple text command via UART.
One 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.
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. (Note 1).
