Preliminary
The MC72000 Integrated BluetoothTM Radio provides a complete, low-power Bluetooth
radio solution. The design is based on Motorola's third-generation Bluetooth architecture
that has set a high standard for interoperability, complete functionality, and compliance with
the Bluetooth specification.
The MC72000 Integrated Bluetooth Radio from Motorola implements the RF and baseband
host controller interface (HCI) of the Bluetooth protocol in a small 7 mm x 7 mm BGA
package. The MC72000 is the ideal solution for low-power, short-range Bluetooth
applications with small size constraints and includes superior performance features like a
dedicated Bluetooth audio processor module and on-chip memory. Debug and production
test are fully supported through the joint test action group (JTAG) interface.
The RF portion of the radio provides a unique combination of high sensitivity, excellent C/I
performance, and low power consumption. These performance parameters are extremely
important to maintaining a robust link in high RF interference environments created by
devices such as mobile phones, high density Bluetooth networks, 802.11b networks, and
microwave ovens.
The MC72000 uses an innovative, highly advanced packaging technique to combine two
die--the RF and baseband functions--into a single, cost-effective package. Motorola's
optimized two-chip architecture avoids compromises between cost and performance that
other one-chip solutions must make. With Motorola's integrated solution, customers get the
best of both. Each die is implemented in its optimal process technology to deliver low cost,
low power, and small size.

2 System Overview
This section provides a brief description of the system for the MC72000.
A system overview is shown in Figure 1
Figure 1. MC72000 Example Application Block Diagram
The main block is the MC72000, which will be described in depth in Section 5, "System Description."
In addition to the MC72000, there are three other blocks:
RF signal Path
Interfaces
Reference clocks
2.1 RF Signal Path
The switch for the RX and TX, the bandpass filter, and the antenna are all found in the RF signal path.
2.2 Interfaces
There are four bi-directional interfaces and one reset that only the host can initiate.
The SSI interface is used for audio purposes.
The UART interface is used for all communication to and from the host (for example, HCI
commands).
The SPI is used for communication with the SEEPROM.
The GPIO pins are used for different configurations set by the MC72000.
2.3 Clocks/Crystals

Preliminary
Electrical Characteristics
The reference clock (12-26 MHz) is used when the MC72000 is active. Note that for a crystal
connected to the on-chip oscillator, the frequency range is 12-15 MHz as shown in Figure 1.
The low power clock (32.768 kHz) is also included and may have high initial tolerance.
3 Electrical Characteristics
The absolute maximum ratings given in Table 1 are stress ratings only, and functional operation at the
maximum is not guaranteed. Stress beyond these ratings may affect device reliability or cause permanent
damage to the device.
WARNING:
This device contains protective circuitry to guard against damage due to
high static voltage or electrical fields. However, normal precautions are
advised to avoid application of any voltages higher than maximum rated
voltages to the high-impedance circuit. Reliability of operation is
enhanced if unused inputs are tied to an appropriate logic voltage level (for
example, either VDD or GND), except for JTAG signals. Refer to
Section 10.12, "JTAG Interface," for details on how to handle JTAG
signals.
