their own technical products after having them careful examined for their suitability
for the intended purpose by experienced technical personnel. The device was not
developed for or intended for use in any specific customer application. The firmware
of the device may have to be adapted to the specific intended modalities of use or
even replaced by other firmware in order to ensure flawless function in the
respective field of applications. Performance data (range, power requirements, etc.)
may depend on the operating environment, the field of application, the configuration,
and method of control as well as other conditions of use; they may deviate from the
technical specifications, the Design Guide specifications or other product
documentation. The exact performance characteristics can be determined only by
measurements subsequent to integration. Variations in the performance data of
mass-produced devices may occur due to individual differences between such
devices. Device samples were tested in a reference environment for compliance
with the legal requirements applicable to the reference environment. No

3 Description of the Modules
BlueMod+P24/P25 are short-range class 2 modules for implementing Bluetooth
functionality into various electronic devices. The modules consists of three major
parts; a baseband controller, a flash memory and a radio that operates in the
license-free 2.45 GHz ISM band.
The BlueMod+P25 is equipped with an internal antenna whereas the
BlueMod+P24 provides an 50 RF interface.
Both data and voice transmission are supported by the modules. Communication
between the modules and the host controller is carried out normally via UART,
USB and PCM interface.

7 Terminal Specifics
7.1 Power supply
The BlueMod+P requires a power supply with the following characteristics:
3,3 V +- 9% low noise
100 mA peak
Due to the technological requirements and the pulsed radio transmission the
supply needs to be fed by an ultra fast linear regulator placed as close as possible
to the VCC pins. Functionality has been verified with the following types: TOREX:
XC6204B272MR or XC6401FF42MR
NOTE: You must ensure that the supply voltage never drops below 2.7 V. Otherwise
the flash contents (firmware and/or configuration data) can get lost.
7.2 RF-ANTENNA
The BlueMod+P24 presents a 50 impedance on the antenna pin.
The BlueMod+P25 presents an integrated ceramic antenna.
If the antenna performance fits not to your requirements or you need antenna
support please contact Stollmann.
It is highly recommended that you follow the design rule given in the Stollmann
Application Note on Antenna design [5].

7.2.1 Typical Radiation Pattern
7.2.2 BlueMod+P25
A first idea can be seen in [3], the radiation pattern from the total module will be
delivered on request. Due to the compromise between module size and antenna
performance, the radiation pattern is a little bit worse against the optimal
circumstances, which are given in [3].
7.3 Reset
The RESET pin is an active low input that can be used to perform a full reset of the
device from an external signal. This pin does not contain an internal pull-up, so it
should be pulled-up externally if not used. The input is Schmitt triggered. A valid
reset signal must be low for at least 5 ms.
7.4 UART Interface – TXD, RXD, CTS, RTS
NOTE: All signals of the serial interface are named according to the EIA232 DTE
definition.
The UART is compatible with the 16450 industry standard and supports 9600, 19.2
K, 38.4 K, 57.6 K, 115.2 K, 230.4 K, 460.8 K, and 921.6 K bits/s 1 rates. Four
signals are provided with the UART interface. The TXD and RXD pins are used for
data while the CTS and RTS pins are used for flow control.
The character representation can be 7 or 8 data bit; no, even or odd Parity; 1 or 2
stop bits.

7.5 USB Interface
7.5.1 D+, D-
The BlueMod+P24/P25 contains a full speed USB version 2.0 compliant interface
capable of directly driving a USB cable. The BlueMod+P24/P25 operates as a USB
peripheral and responds to requests from a USB master host controller. For the
BlueMod+P24/P25 to operate in USB mode, GPIO [15] must be pulled high.
Note: If your application requires operation in UART only mode, then
connecting the USB D+ pin to VCC and the USB D- to GND using 10k ohm
resistors will ensure that the USB circuit remains in an idle mode.
7.5.2 USB Pull-Up Resistor
A 1.5K pull up resistor needs to be connected between GPIO [2] and the USB D+
line. This pulls the USB D+ line high when the BlueMod+P24/P25 is ready for
enumeration, signaling to the host controller that the BlueMod+P24/P25 is a full
speed (12Mbps) USB device.

R2 Rint ~50k
In USB self-
powered mode, the BlueMod+P24/P25 is powered from its own power supply and
not from the USB Vbus line. In order to detect when the USB Vbus line is powered
up, the USB Vbus line is monitored by GPIO [3] through a voltage divider formed
by R1 and Rint as shown in Figure 4. A 20K series resistor (R1) with a 50K
shunt resistor (Rint) will generate close to +3.3Vdc at the GPIO [3] pin. This will
produce around 55uA of leakage current through the voltage divider. If less
leakage current is desired, the internal pull down resistor can be disabled and an
external voltage divider (formed by R1 and R2) can be used to minimize the
leakage current.
Figure 3. Typical USB connection for Self Powered Mode
7.5.4 USB Bus-Powered Mode
In USB bus-powered mode, the BlueMod+P24/P25 is powered from the USB Vbus
line by means of a Low Drop Out (LDO) Voltage Regulator. When choosing the
LDO Voltage Regulator for supplying the +3.3V power to the BlueMod+P24/P25 ,
some factors that need to be considered are:
1. The voltage specification for the USB Vbus line is +4.75V to +5.25V.
2. The total current required (average and peak) for the design.
3. The voltage regulator’s drop out voltage vs. output current.
4. The voltage regulator’s power dissipation over the operating temperature range.
5. Filtering requirements on the USB Vbus line to attenuate noise above the
voltage regulator’s bandwidth.
6. The suspend state current draw.

7.6 GPIO Interface
All GPIOs are capable of sinking and sourcing 2mA of I/O current. These terminals
are 5V tolerant.
NOTE: The designer should avoid applying a voltage to the GPIOs prior to
powering-up the device, this can cause reset stability issues with the
ZV4002/ZV4301 device.
GPIO [0] to GPIO [7] are internally pulled down with 50K (nominal) resistors.
GPIO [8] to GPIO [15] are internally pulled up with 50K (nominal) resistors.
The GPIO pins of the BlueMod+P24/P25 may be multiplexed with other functions as
described in chapter 0. This multiplexing is based on the application code loaded
into the BlueMod+P24/P25. In addition, certain GPIO pins have special functionality
based on the application.
GPIO [0] is used as the CODEC control clock for applications using an external
audio CODEC.

7.7 PCM Interface
PCM or Pulse Code Modulation is a sampling technique for digitizing analog
signals. The PCM interface for voice applications is provided via the PCM_OUT,
PCM_IN, PCM_CLK and PCM_SYNC pins.
The PCM interface always acts as the master and uses a 1MHz bit clock. The Clock
duty cycle is 5% / 95%. The Frame Clock is 8Khz. The data format is 14bit linear
2th complement
Figure 4. PCM timing
The BlueMod+P24/P25 interfaces directly with the following CODECs:
OKI Semiconductor MSM 7732-01
OKI Semiconductor MSM 7716
In this scenario the use of GPIO [0], GPIO [1] and GPIO [6] is required to
control/program the CODEC.
Interface examples can be seen in [1] Figure 8 and 9.

We recommend the same dimension for the solder paste screen.
The solder screen thickness depends on your production standard, we recommend
120µm to 150µm.
IMPORTANT:
Please be careful with the area under the module to avoid short cuts.
Engineering Sample Status:
The bottom side from the BlueMod+P24/P25 is fully coated, except the vias!
Mass Production Status:
The bottom side from the BlueMod+P25 is fully coated, also the vias!
To give an optimized antenna performance the restricted area should have no
ground and the minimum dimension should be carry out, depending on your
possible space.
If you have any questions on this point, we are open to discuss your individual
situation.
