Description
DA14708 builds off the successes of Renesas’ SmartBond™ line, with Arm® Cortex®-M33F at 160MHz as integrated application processors, 2D graphics processor, Voice Activity Detector (VAD), and Power Management Unit (PMU). With its ultra-low-power radio transceiver offering +6dBm output power, and -97dBm sensitivity combined with its software-configurable and upgradeable protocol engine (MAC), the DA14708 is capable of supporting Bluetooth® low energy as well as multiple other 2.4GHz protocols. These unique features make the DA14708 the first product in the wireless SoC space to offer this level of integration.
