LMX9838

Bluetooth^®Serial Port Module

1.0 General Description

The on-chip Patch RAM provided for lowest cost and risk, al-

lows the flexibility of firmware upgrade.

The National Semiconductor LMX9838 Bluetooth Serial Port

module is a fully integrated Bluetooth 2.0 baseband controller,

2.4 GHz radio, crystal, antenna, LDO and discreets; com-

bined to form a complete small form factor (10 mm x 17 mm

x 2.0 mm) Bluetooth node.

The module is lead free and RoHS (Restriction of Hazardous

Substances) compliant. For more information on those quality

standards, please visit our green compliance website at

http://www.national.com/quality/green/

All hardware and firmware is included to provide a complete

solution from antenna through the complete lower and upper

layers of the Bluetooth stack, up to the application including

the Generic Access Profile (GAP), the Service Discovery Ap-

plication Profile (SDAP), and the Serial Port Profile (SPP).

The module includes a configurable service database to fulfil

service requests for additional profiles on the host. Moreover,

the LMX9838 is qualified as a Bluetooth endproduct, ready to

be used in the end application without additional testing and

license cost.

Based on National’s CompactRISC^®16-bit processor archi-

tecture and Digital Smart Radio technology, the LMX9838 is

optimized to handle the data and link management process-

ing requirements of a Bluetooth node.
