LMX5452

Micro-Module Integrated Bluetooth®1.2 Baseband

Controller and Radio

1.0 General 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

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 Com-

pactRISCTM 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 com-

plete 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, sup-

porting 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 information on

those quality standards, please visit our green compliance

LIFE SUPPORT POLICY

NATIONAL’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS

WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT AND GENERAL COUNSEL OF NATIONAL SEMICONDUCTOR

CORPORATION. As used herein:

1. Life support devices or systems are devices or systems

which, (a) are intended for surgical implant into the body, or

(b) support or sustain life, and whose failure to perform when

properly used in accordance with instructions for use

provided in the labeling, can be reasonably expected to result

in a significant injury to the user.

2. A critical component is any component of a life support

device or system whose failure to perform can be reasonably

expected to cause the failure of the life support device or

system, or to affect its safety or effectiveness.

BANNED SUBSTANCE COMPLIANCE

National Semiconductor manufactures products and uses packing materials that meet the provisions of the Customer Products

Stewardship Specification (CSP-9-111C2) and the Banned Substances and Materials of Interest Specification (CSP-9-111S2) and contain

no ‘‘Banned Substances’’ as defined in CSP-9-111S2.

Leadfree products are RoHS compliant.
