Hardware
4.4.4Memory
The MC72000 has embedded memory of 256 Kbytes of ROM and 64 K of RAM. The file system and
application can be uploaded from a host system, or a low-cost serial EEPROM (four-wire connection). For
more information on the contents and structure of the MC72000 memory, please refer to the Bluetooth Platform Solution Embedded System User’s Guide. This is accessible from the document overview on the
Development Kit CD.
4.4.5UART Interface
The UART interface is embedded in the MC72000. However, an external level converter is needed. For
this purpose, the MAX3237 1.0 Mbit level converter is used. The level converter is connected to the
MC72000 and a female 9-pin D-sub. The connection between the level converter and the MC72000 is
passed through a jumper block in order to aid debugging, and, if ever needed, to use a different type of
level converter.
4.4.6CODEC Interface
The audio interface consists of the Motorola MC145483 CODEC, a 4-pin header and a 4/4p amp
connector. Sampling rate is configured at 7.8125 kHz.
4.4.6.1Codec Setup and Configuration
In the current (Motorola CODEC) configuration for the 72000 Development Kit, the CODEC can only be
configured as a slave, which is done by the application at startup. Therefore, the MC72000 IC will be
configured as the SSI master, meaning that the MC72000 IC generates all SSI control signals. In practice,
the CODEC bit clock is tied electrically to the master clock.
There are certain constraints on the available clock frequencies; specifically, the frequency can only be
integer factors of the baseband’s master clock, which is 24 MHz. The Motorola CODEC expects a 2.048
MHz master clock, but due to these limitations, none of the available integral frequencies fit the CODEC
exactly. Therefore, a slight mismatch in the order of two per cent exists. To be exact, the CODEC expects
a 2.048 MHz master clock, but gets 2.000 MHz.
The frame sync generated by the MC72000 IC can only by an integer factor of the master clock (bit clock),
and is selected as 1/256th, resulting in:
•Frame sync: 2000 kHz / 256 = 7.8125 kHz
This slight mismatch does not cause any audio degredation. Interpolation copes with the synchronization
seamlessly. The degradation of the frequency characteristic of the system from runnning on a slightly
lower sample frequency is not significant. (The pass-band upper frequency is 3.9 kHz instead of 4.0 kHz).

5.3Obtaining Type Approval
Customers of Motorola Bluetooth chipsets will face some Bluetooth qualification and regulatory
requirements for their products. The following lists the requirements for the major markets as defined by
Motorola as tier 1 countries: Australia, Canada, Europe (15 + 4 EFTA countries), Japan, New Zealand and
the US. A number of other countries worldwide will accept the test reports made for Europe and/or US
approval; for more information, please go to: http://www.bluetooth.org/member/regulatory.
Motorola chipsets (radio/baseband) are pre-qualified as Bluetooth components; for more information,
please go to: http://qualweb.opengroup.org/Template2.cfm?LinkQualified=QualifiedProducts. Also any
variants of Motorola software stacks will be pre-qualified. The assumption of pre-qualification provides
that customers will implement the radio module (radio chip including surrounding components and print
layout) without any changes.
5.3.1Requirements for Bluetooth Qualification
Baseband chipset will be used as a pre-qualified component and do not require re-testing.
Any incorporated variant of Motorola software stack will be used as a pre-qualified component and do not
require re-testing.
Radio will need to be re-tested in the product layout for the 8 (of 16) test cases listed in the following table.
(For more information, see “The Bluetooth Qualification Program Reference Document (BQ PRD)” on the
Bluetooth Qualification Program Website: http://qualweb.bluetooth.org/Template2.cfm.)

If changes are made to the 72000 Development Kit radio module BOM or layout, all 16 Bluetooth test
cases will be required to be re-tested. Depending on the nature of changes to the radio, re-testing might
only be necessary in normal temperature. This has to be decided by the BQB in each case.
5.3.2Requirements for Regulatory Type Approval
The following regulatory testing needs to be made:
•For CE-marking: EN 300 328-2 (emission), EN 301 489-17 (EMC), EN 60950 (safety)
•For Japan approval: ARIB T-66.
•For FCC grant: CFR47 part 15.205, 15.209 and 15.247 (except 15.247e: processing gain)
NOTE:
As Motorola radios will be approved by FCC as radio modules and the
FCC testing can be avoided for regulatory purposes for radio modules,
provided no changes are made to the radio module BOM or layout, it will
still be necessary to perform the Out-of-Band Spurious
Emissions-radiated-test of part 15.209.
The product might be subject to additional product specific regulations, such as PSTN regulations and
other.
Type approval applications have to be filed to the national authorities for each product.
Documentation submitted for type approval can vary from country to country, but will in general include:
test reports, pictures, BOM, schematics, PCB layouts, product descriptions (block diagrams), antenna
information, SAR statements (see below), label/manual information (legal text) and manufacturer
information.
Both in Europe and US regulators are currently working on new sets of rules for combined radio
equipment as well as rules for SAR. Test requirements for SAR (including combined radio) will most
likely be topical within the next year.
