Fujitsu Intros New BLE Wireless Modules

Fujitsu Components America has released its FWM7BLZ20B Bluetooth 5.0 Low Energy wireless modules. The new modules are designed to meet the high communication speed requirements of Internet of Things (IoT) devices and applications.

The FWM7BLZ20B series is powered by Nordic Semiconductor's nRF52832 system-on-chip (SoC) and features lower power consumption than classic Bluetooth (BR/EDR), increased communication speed (X2 speed), 255 bytes of LE advertising extensions and other expansions to Bluetooth 4.x. The symbol and data rates accommodate 1Mbps and improved 2Mbps to facilitate communication speed with other Bluetooth devices, according to the company.

The series includes two models. The FWM7BLZ20B module contains Fujitsu's embedded firmware, enabling Bluetooth protocol stack handling by simple text commands via UART. It features a GATT Direct Access Function, which enables access with other modules through the GATT layer commands. With this function, host equipment can communicate simultaneously with up to eight peripherals. It also facilitates communication with other manufacturers' Bluetooth modules.

The FWM7BLZ20B-109077 is a blank module without Fujitsu firmware. Users can develop unique firmware, including X2 speed and LE advertising extension using tools provided by Nordic Semiconductor. This module includes embedded NFC support function to pair with NFC-embedded devices via external antenna. Samples are available now.
