SYSTEM LEVEL BLOCK DIAGRAM
A typical application example of the XE1402 is shown in Figure 1. The Semtech Bluetooth baseband controller XE1402
bridges the Host Controller Interface (HCI) to the Radio Interface not requiring any external components. The on-chip
Serial Peripheral Interface (SPI) allows the direct interface to a standard, external non-volatile memory for example to
store application specific parameters as Module revision, BD_Address and configuration parameters.
If the XE1402 detects a non-volatile memory at the SPI port, the baseband controller is able to configure the Bluetooth
lower protocol system on its own. In this case no interaction from the Host controller would be required.
Vendor specific HCI commands can be used to control the optional memory by any Host Controller via the on chip 4-wire
UART interface.

Figure 1: Bluetooth Data Application
The Semtech Bluetooth Baseband controller operates completely independently from tasks running above HCI. Software
Development, test and qualification of the higher protocol layers, profiles and application layer can be done completely
independent from the lower protocol stack.
Depending on the complexity of the application any host processor can be chosen. On the host processor the user has to
run their own application software as well as the upper layer Bluetooth protocol stack software. Qualified upper Bluetooth
protocol software running on various controllers – 8, 16 and 32 bit architectures - can be supplied in combination with the
Semtech baseband chip.
This system architecture definitely eases the software development process, the Bluetooth qualification and guarantees
the highest possible flexibility. When compared to alternative solutions, the usage of different semiconductor processes
enables the manufacturer to benefit from greater volume production yields, superior RF and baseband performance and
a reduced number of external components.
As only a few Bits of code must be programmed to initialize the total Bluetooth system, volume production and system
maintenance through software updates becomes easy.
The Bluetooth qualification process for the final application is simplified by the fact that the XE1402 is purely ROM based
and fully Bluetooth qualified.

The XE1402 does not need any external memory and represents a ROM version of the Lower Bluetooth Protocol Stack
up to HCI.
During start-up, an initialisation routine is required to properly configure several parameters of the XE1402 and the radio
device. The initialisation can be done from the host controller via the HCI interface or all application specific parameters
can be stored in a non-volatile memory directly connected at the on chip SPI port.
The fully embedded HCI software running on the XE1402 provides the following Bluetooth functionality:
•
•
•
•
•
•
•

XE1402
The VDD_PAD [Pin 38] is the main supply input pin for the integrated power management unit. The supply can be
unstable but a blocking capacitor is recommended. VDD_REG [Pin 1] is the regulator output pin providing a stabilized
1.8V supply for any external components. In this configuration a 4.7 uF capacitor should be connected between
VDD_REG [Pin1] and ground.
The levels for SPI (Serial Peripheral Interface) are fixed to1.8V. The interface level for the UART as well as the radio port
can be selected by applying the appropriate interface voltage at VDD_IO [Pin 2] for the radio interface and at
VDD_IO_DIG [Pin 18] for the UART.
Depending on the radio operating voltage, VDD_IO [Pin 2] should be connected to a 3V supply (e.g. VDD_PAD) or to any
1.8V supply (e.g. VDD_REG). VDD_IO_DIG [Pin 18] sets the UART interface levels. This allows the use of any host
controller supply voltage ranging from 1.8V to 3.6V. For details see the various configuration examples.
The supply for the XE1402 core must be applied to VDDD [Pin40]. The nominal core supply voltage is 1.8V. An external
connection between VDD_REG [Pin1] and VDDD [Pin40] is required to power the core when using supply voltages above
1.8V.
If several supply voltages are available within the system e.g. 1.8V and 3V, the level shifter can be directly connected to
the appropriate power source. For further details see the configuration examples on the following pages. See also the
"Comment" column at the chapter Terminal Description.
Whenever possible, the lowest possible interface voltage should be used to reduce the systems power consumption.
3.2.1 Single 1.8V supply - configuration example
The following configuration can be used if a regulated 1.8V supply is available. The radio, UART, generic Serial

3.3 CLOCKING SOURCES
The radio circuit provides the high and low frequency system clock for the XE1402. Besides a low frequency clock of 32
kHz, two baseband clocks are supported, 13 MHz and 16 MHz.
The XE1413 radio typically provides a 13 MHz clock. Programmable dividers on the radio chip can be used to derivate
the low frequency clock from the high frequency clock.
CLK_IN [Pin 21] input is used to provide the baseband with the main clock. The required clocks for any peripherals are
internally derived from the CLK_IN signal.
3.4 RADIO INTERFACE
The radio type can be set with the RADIO_TYPE [Pin 19] pin. The XE1402 automatically adjusts the internal divider ratios
to generate a common time base. The XE1402 does not require any additional crystal or external clock sources.
The XE1402 is able to interface without any additional logic to the XE1413 and the CX72303 radio.
The voltage levels at the RADIO_TYPE pin should be:
RADIO_TYPE [Pin19] : XE1413 or CX72303 Radio

= 0V / VSSDx
= 1.8V or 3V depends on VDD_IO_DIG

3.5 GENERIC SERIAL PERIPHERAL INTERFACE - SPI
The general purpose SPI of the XE1402 can be used to interface and initialize any peripherals, as for example external
non-volatile memory. The SPI is fixed to operate at 1.8V.
Vendor specific HCI commands are defined to program the peripherals via the HCI. As the SPI is fully transparent at the
Host Controller Interface (HCI), SPI read/writes command can be directly issued from the host controller, not interfering
ongoing lower layer real time Bluetooth tasks.
The Serial Peripheral Interface consists of 4 lines with the following functionality.

3.8 BLUETOOTH SEQUENCER
The Bluetooth Sequencer includes all hardware blocks required to comply with the Bluetooth rev. 1.1 communication
standard. The XE1402 is already prepared for the next generation and fully compliant with the Bluetooth rev. 1.2
standard.
This building block manages all tasks of the lower layer Bluetooth protocol up to the HCI. It ensures a “transparent” usage
of the Bluetooth wireless communication via the HCI. It receives the data directly from the higher layers and then
autonomy performs the various transmits, receives and protocol timing tasks without any interaction from the host
controller. The host processor communicates through a standard UART with the XE1402.

4.3 TYPICAL AVERAGE POWER CONSUMPTION
The measurements are done based on several configuration examples. All typical averaged values are measured at
room temperature (25°C) using the CX72303 Bluetooth radio in a Class 2 (typ. +3.5 dBm) mode operating at 1.8V. A high
frequency system clock of 13 MHz provided by the radio chip was used. The default UART speed is 115 kbit/s.

4.4 SYSTEM POWER CONSUMPTION - 13 MHZ AND 32 KHZ CRYSTAL
To conserve energy the XE1402 automatically disables the 13 MHz oscillator of the radio whenever the various operation
modes allow running on the low frequency 32 kHz clock. Both clock signals are provided by the radio and generated on
two different oscillators.

4.5 SYSTEM POWER CONSUMPTION - 13 MHZ CRYSTAL ONLY
To conserve energy the XE1402 automatically disables the 13 MHz oscillator of the radio whenever the various operation
modes allow running on the low frequency 32 kHz clock. In this configuration the XE1413 or CX72303 radio is deriving
the 32 kHz clock from the 13 MHz oscillator by using its internal dividers. Both clock signals are provided by the radio
using the 13MHz oscillator of the radio chip.
