8.0 Functional Description
8.1 BASEBAND AND LINK MANAGEMENT
PROCESSORS
Baseband and Lower Link control functions are imple-
mented using a combination of National Semiconductor’s
CompactRISC 16-bit processor and the Bluetooth Lower
Link Controller. These processors operate from integrated
ROM memory and RAM and execute on-board firmware
implementing all Bluetooth functions.
8.1.1 Bluetooth Lower Link Controller
The integrated Bluetooth Lower Link Controller (LLC) com-
plies with the Bluetooth Specification version 2.0 and
implements the following functions:
■
Adaptive Frequency Hopping
■
Interlaced Scanning
■
Fast Connect
■
Support for 1, 3, and 5 slot packet types
■
79 Channel hop frequency generation circuitry
■
Fast frequency hopping at 1600 hops per second
■
Power management control
■
Access code correlation and slot timing recovery
8.1.2 Bluetooth Upper Layer Stack
The integrated upper layer stack is prequalified and
includes the following protocol layers:
■
L2CAP
■
RFComm
■
SDP
8.1.3 Profile support
The on-chip application of the LMX9830 allows full stand-
alone operation, without any Bluetooth protocol layer nec-
essary outside the module. It supports the Generic Access
Profile (GAP), the Service Discovery Application Profile
(SDAP), and the Serial Port Profile (SPP).
The on-chip profiles can be used as interfaces to additional
profiles executed on the host. The LMX9830 includes a
configurable service database to answer requests with the
profiles supported.
8.1.4 Application with command interface
The module supports automatic slave operation eliminating
the need for an external control unit. The implemented
transparent option enables the chip to handle incoming
data raw, without the need for packaging in a special for-
mat. The device uses a pin to block unallowed connections.
This pincode can be fixed or dynamically set.
Acting as master, the application offers a simple but versa-
tile command interface for standard Bluetooth operation
like inquiry, service discovery, or serial port connection.
The firmware supports up to seven slaves. Default Link Pol-
icy settings and a specific master mode allow optimized
configuration for the application specific requirements. See
also Section "Integrated Firmware" on page 30.
8.1.5 Memory
The LMX9830 introduces 16 kB of combined system and
Patch RAM memory that can be used for data and/or code
upgrades of the ROM based firmware. Due to the flexible
startup used for the LMX9830 operating parameters like
the Bluetooth Device Address (BD_ADDR) are defined dur-
ing boot time. This allows reading out the parameters of an
external EEPROM or programming them directly over
UART.
8.1.6 External memory interfaces
As the LMX9830 is a ROM based device with no on-chip
non volatile storage, the operation parameters will be lost
after a power cycle or hardware reset. In order to prevent re
initializing such parameters, patches or even user data, the
LMX9830 offers two interfaces to connect an external
EEPROM to the device:
■
μ-wire/SPI
■
Access.bus (I
2
C compatible)
The selection of the interface is done during start up based
on the option pins. See Table 17 on page 17 for the option
pin descriptions.
8.1.7 μ-wire/SPI interface
In case the firmware is configured by the option pins to use
a μ-wire/SPI EEPROM, the LMX9830 will activate that inter-
face and try to read out data from the EEPROM. The exter-
nal memory needs to be compatible to the reference listed
in Table 10 on page 13. The largest size EEPROM support-
ed is limited by the addressing format of the selected NVM.
The device must have a page size equal to N x 32 bytes.
The firmware requires that the EEPROM supports Page
write. Clock must be HIGH when idle.
