The LMX5452 is a highly integrated Bluetooth 1.2 compliant solution. The integrated baseband controller and 2.4 GHz radio combine to form a complete, small form-factor (6.1 mm x 9.1 mm x 1.2 mm) Bluetooth node. The baseband controller has a standard Host Controller Interface (HCI). Based on the National Semiconductor CompactRISCTM 16-bit processor, the LMX5452 is optimized to handle the audio, data, and link management processing requirements of a Bluetooth node. The on-chip memory, ROM, and Patch RAM provide lowest cost and minimize design risk with the flexibility of firmware upgrades.
