An circuit includes a first wireless interface circuit that transceives packetized data between a host module and a first external device in accordance with a first wireless communication protocol. A second wireless interface circuit transceives packetized data between the host module and a second external device in accordance with a second wireless communication protocol. The second wireless interface circuit includes at least one module that is shared with first wireless interface circuit, the module having a first state where the module is operational and a second state corresponding to a low-power state. The first wireless interface circuit and the second wireless interface circuit operate in accordance with a wireless interface schedule that includes a first time interval where the first wireless interface device and the second wireless interface device contemporaneously use the at least one module in the first state and a second time interval where the at least one module is in the second state.
