3 Application Interface
3.1 Power Supply
The BlueMod+C11/G2 has two power supply rails, which always should be kept on
the same voltage level. Although we recommend using two different power rails, it is
as well possible to feed both rail from a single supply.
Pin # Signal Usage
C-13 3V3 Supply for digital and low power RF circuitry,
C-16 3V3-PA Supply for RF Amplifier
C-14 GND Reference Supply
C-15 GND Reference Supply
The pin order is made such that on the customer hardware directly at the pins of
each supply pair pins (C-13/C14) and pins (C-16/C-15) a 10uF X5R ceramic capaci-
tor with for example a 1206 footprint can be placed for decoupling. It is recom-
mended to add further smaller value ceramic capacitors. These values depend on
noise frequencies on the supply rail. The following picture shows a sample layout
with two linear regulators in SOT23-5 housings and various capacitors in SMT
shapes 0402, 0805 and 1206.
Fig. 2 Sample Layout Power Supply

BlueMod+C11/G2
Hardware Reference
Release r05 www.stollmann.de Page 10 of 44
Each supply rail should be fed with 3,3V, Range 3,0V to 3,6V incl. Noise, low noise
from a linear regulator with fast transient response. Stollmann suggest using two
pcs.
TOREX: XC6204B332MR
regulators, so that the fast current transients of the class1 RF power amplifier do not
interfere with sensitive PLL circuitry of the low power RF circuitry.
For layout guidelines please see sample implementation Stollmann reference design
BlueMod+Eval/C11/G2.
Excessive noise or too slow current transient response on the supply rails may have
an impact on the RF performance.
3.2 Power-up slew-rate
The Power up slew-rate for the BlueMod+C11/G2 must be more then 6V/ms for
proper startup of the AT91SAM7S Controller used on the BlueMod+C11/G2.
Figure 3 shows an example circuit for a power supply. The Output Voltage of the
Regulator is enabled by the Threshold Voltage of a RESET-Circuit, when VCC
Startup ramp reaches a valid Voltage.

3.3 Power-On-Reset
The BlueMod+C11/G2 is equipped with circuitry for generating Power-On Reset and
to provide under-voltage supervision. An integrated circuit type Maxim DS1818R
provides this functionality.
A reset is generated if the 3.3V supply rail including noise falls below 2,8V to 2,97V.
Via Pin A-1 an external reset can be generated by holding EXT-RES# at ≤0.3V for
≥10ms. A 74LVC14 Schmitt Trigger gate with a 1kR5/10nF low-pass filter at the
input is implemented to avoid false reset pulse recognition due to EMC effects.

If EXT-RES# is not used, it may be left open or tied to VCC.
3.4 Serial Interface
The interface functionally corresponds to the norm V.24 / RS-232 but has TTL-level.
• Transmission speeds 300 bps – 921600 bps (asynchronous)
• Character representation: 7 to 9 Bit, even, odd, mark, space or no Parity, 1, 1.5
or 2 stop bits
• Half duplex or full duplex
• Hardware flow-control (RTS/CTS)
Note: All signals of the serial interface are named according to the EIA232 DTE
definition.
3.4.1 RS-485 Support
For RS-485 support the serial interface has to be connected to an external Trans-
ceiver, we suggest the MAX3491E from Maxim Integrated Products, due to it sup-
ports full duplex transmissions.

3.5 GPIO Interface
All user signals, except for EXT-RES#, which is routed via an Schmitt Trigger gate,
are connected directly to port pins of the ATMEL AT91SAM7S256 CPU. Except for
USB signals DP, DM and GPIO(4), no additional pull-up or down resistors are im-
plemented, so that the I/O characteristics of the ATMEL CPU apply. These are
• 3V3 logic 5V tolerant
• V
IL

IH
min = 2.0V, V

max = 5.5V
• V
OH
min = VCC – 0.4V @ I
O
= 8mA, V
OL
< 0.4V @ I
O
= 8mA
• LED’s can be driven directly on specific GPIO lines when I
o
stays below 8mA
All current consumption data in this document are given with I
O
(GPIO) = 0mA
See chapter 5 Electrical Characteristics for detailed information.
• All I/O signals except USB, GPIO(4) and JTAG are connected directly from the
AT91SAM7S pins to the user accessible stamp pins. Therefore, the electrical
characteristics of the I/O pins are programmable in regard to direction, pull-up
resistor, function, push-pull or open drain. Please see specific application soft-
ware documentation for details. After reset, all GPIOs have pull-ups activated.
GPIO10, GPIO8 and TXD have 50kR to 300kR pull-ups, all other I/Os have 5kR
to 20kR pull-ups
3.6 Alternate GPIO/IO Functions
Application specifically dedicated GPIO or IO pins can be programmed to alternative
functionalities. Then pin functionality and direction are fixed for the activated function
block. Many GPIOs are used by the SPP application. See chapter SPP Configura-
tion. Probably some of them can be released for use by other function blocks. Co-
functionality of blocks has to be carefully considered, because pin multiplexing pos-
sibilities are fixed by the ATMEL AT91SAM7S CPU and using a function block often
causes that other function blocks can’t be used at the same time. Please refer to the
ATMEL data sheet AT91SAM7Sxxx Rev. F for complete information. The possibili-
ties depicted in the following chapters are a subset only.
The following function blocks may be usable on the BlueMod+C11/G2:

3.6.2 Synchronous Serial Interface
The Synchronous Serial Interface is capable of handling the protocols I2S, Short
Frame Sync, Long Frame Sync and other Telecom protocols. Receiver and trans-
mitter do act independently. Due to multiplexing interdependencies, the SSC is only
available with the Transmitter clock signal TK used for both directions if the UART IF
is enabled. JTAG reset, signal /ATRST, is also not available, if the SSC signal RF,
Receiver Frame Sync is used.

3.6.3 Multi Channel PWM Controller
Each PWM channel can be programmed individually in regard to IO pin assignment
and PWM functionality. Therefore, PWM application designers can choose a proper
channel and pin for their application with the chance not to interfere with other nec-
essary interfaces.

3.7 Bluetooth radio Interface
The BlueMod+C11/G2 offers three population variants for the antenna
1) The BlueMod+C11/G2/AE variant presents a 50Ωimpedance antenna interface
on a Radiall UMP connector, type R107103020. See http://www.radiall.com/
2) The BlueMod+C11/G2/AI variant presents an integrated ceramic antenna.
In both cases the Pins A-26 – A-28 can be left unconnected.
3) The BlueMod+C11/G2/AP variant presents a 50Ωimpedance antenna interface
on pin A-27 with adjacent GND pins A-26 and A-28. In this case Pin A-26 and A28
shall be connected directly to the reference GND plane. Signal routing of the RF
signal on customer PCB has to be implemented with 50R micro-strip line technique.
If the antenna performance does not meet your requirements or you need antenna
support, please contact Stollmann.
3.8 Etc.
For SW development purposes on the module pins a full JTAG interface connected
to the ATMEL CPU is implemented.
