Murata has announced the LBEP series of wireless modules providing wireless LAN, Bluetooth® and Bluetooth low energy (BLE) connectivity.

Based around the WiLink™ 8.0 solutions from Texas Instruments, the miniature modules measure just 8.8 x 9.9 x 1.3 mm and offer a complete low cost, highly integrated approach to providing wireless connectivity to a wide range of consumer, industrial and commercial applications. The modules include an integrated crystal and require no additional external components. Host connectivity, antenna and power are the only connections required. A slow clock input can be used to support a deep sleep mode.

“The market is demanding high performance Wi-Fi and Bluetooth/Bluetooth low energy connectivity solutions for a variety of new applications including multi-media, point-of-sale and portable data terminals for the retail and enterprise space. Murata’s modules, based on TI’s WiLink 8.0 devices, deliver the size, performance and integration to meet manufacturers’ needs,” said Adnan Nishat, WiLink product manager, Wireless Connectivity Solutions, TI.

The LBEP5CLWMC module provides both 2.4 GHz (IEEE802.11 g/b/n and Bluetooth 4.0) and 5 GHz (IEEE802.11a) connectivity. This module uses the TI WL1803/1833 combo connectivity solution. Host interfaces of SDIO are used for the wireless LAN and UART or PCM for Bluetooth.

The LBEP5CLWTC module provides 2.4 GHz IEEE802.11b/g/n connectivity and uses the TI WL1831/1801 devices.

The modules require a 3.0 to 4.2 V DC supply and 1.8V DC for I/O.
