DESCRIPTION
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 × 9.1 mm × 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.
The firmware supplied in the on-chip ROM supports a complete Bluetooth Link Manager and HCI with
communication through a UART or USB interface. This firmware features point-to-point and point-to-multipoint
link management, supporting data rates up to 723 kbps.
The radio employs an integrated antenna filter and switch to minimize the number of external components.
The radio has a heterodyne receiver architecture with a low intermediate frequency (IF), which enables the IF
filters to be integrated on-chip. The transmitter uses direct IQ-modulation with Gaussian-filtered bit-stream data, a
voltage-controlled oscillator (VCO) buffer, and a power amplifier.
The LMX5452 module is lead free and RoHS (Restriction of Hazardous Substances) compliant. For more
