LMX5453SM/NOPB

Product Summary

The LMX5453 is a highly integrated Bluetooth 2.0 compliantsolution. The integrated baseband controller and 2.4 GHzradio combine to form a complete, small form-factor (6.1 mmx 9.1 mm x 1.2 mm) Bluetooth node.The on-chip memory, ROM, and Patch RAM provide lowestcost and minimize design risk with the flexibility of firmwareupgrades.The firmware supplied in the on-chip ROM supports a com-plete Bluetooth Link Manager and HCI with communicationthrough a UART or USB interface. This firmware featurespoint-to-point and point-to-multipoint link management, sup-porting data rates up to 723 kbps
