Ezurio TiWi5 Integrated Transceiver Modules

Ezurio TiWi5 Integrated Transceiver Modules are high-performance radio modules operating in the 2.4GHz and 5GHz bands, supporting single stream WLAN data rates to 65Mbps and BLUETOOTH® 2.1+EDR (2Mbps and 3Mbps) and BLUETOOTH 4.0 (BLE) in a cost-effective, pre-certified footprint. The modules realize the necessary PHY/MAC layers to support WLAN applications in conjunction with a host processor over an SDIO interface. TiWi5 also provides a BLUETOOTH platform through the UART or btSPI HCI transport layer. Both WLAN and BLUETOOTH share the same antenna port. The module requires only 2 power supplies, of which one may be a direct connection to a battery. The TCXO used to derive radio performance is included within the module. TiWi5 is pin-for-pin compatible with the TiWi-R2 module.
