It delivers up to 150 Mbps data rate through SDIO 3.0 or SPI host interfaces. The integrated PA, LNA, and T\/R switch minimize external component count. With deep sleep power management and WPA2 security, it targets cost-sensitive IoT devices, printers, IP cameras, and set-top boxes. The WLBGA package provides a compact footprint for space-constrained designs.","working_principle":"The BCM43217 integrates a 2.4 GHz radio transceiver, baseband processor, MAC layer, and Bluetooth core on a single die. The 2x2 MIMO architecture uses two spatial streams to improve throughput and range compared to single-antenna designs. The Wi-Fi MAC implements CSMA\/CA channel access, fragmentation, and power save polling. The SDIO 3.0 host interface provides high-throughput data transfer to the host processor at up to 100 MB\/s. The integrated Bluetooth coexistence mechanism uses time-division multiplexing to prevent Wi-Fi and Bluetooth from transmitting simultaneously, with hardware signaling between the two radio subsystems. The deep sleep mode reduces power consumption to microamp levels by shutting down the radio and clock synthesizer while maintaining register state.","pin_description":"\n
