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 recommend-
ed 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 r09 www.stollmann.de Page 10 of 54
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 DCE
definition.

3.4.2 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
JTAG, USB signals DP, DM and GPIO(4,10), no additional pull-up or down resistors
are implemented, so that the I/O characteristics of the ATMEL CPU apply. These
are
•3V3 logic 5V tolerant
•VIL max = 0.8V, VIH min = 2.0V, VIH max = 5.5V
•VOH min = VCC – 0.4V @ IO= 8mA, VOL < 0.4V @ IO= 8mA
•LED’s can be driven directly on specific GPIO lines when Iostays below 8mA
and the specific GPIO line is specified for Iomax = 8mA.
All current consumption data in this document are given with IO(GPIO) = 0mA
See chapter 5 Electrical Characteristics for detailed information.
•All I/O signals except USB, GPIO(4) with 47k5 pull-down, GPIO(10) with 10k
pull-up and JTAG each with 100k pull-up except for TDO 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 applica-
tion software documentation for details. After reset, all GPIOs have pull-ups ac-
tivated. GPIO10, GPIO8 and TXD have 50kR to 300kR pull-ups, all other I/Os
have 5kR to 20kR pull-ups
•In reference to the ATMEL AT01SAM7S256 Errata Sheet 6173B-ATARM item
no. 18, the on-chip pull-up resistors on all GPIO pins, except for GPIO[8,10,16]
pull to min. (VDD -0,65V) rsp. to max. (VDD -0,45V). VDD is 3,0V to 3,6V. Use
of ext. pull-ups on open inputs is recommended.
3.6 Alternate GPIO/IO Functions
Application specific GPIO or IO pins can be programmed to alternate functions.
Then pin function and direction are fixed for the activated function block. Many
GPIOs are used by the SPP application. See chapter SPP Configuration. 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 possibilities are lim-
ited 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 possibilities de-
picted 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..

3.7 Bluetooth Radio Interface
The BlueMod+C11/G2 offers three population variants for the antenna
1) The BlueMod+C11/G2/AI variant presents an integrated ceramic antenna.
Pins A-26 and A28 shall always be connected directly to the reference GND plane
3) The BlueMod+C11/G2/AP variant presents a 50Ω impedance 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 JTAG
For software development purposes a JTAG interface, connected to the ATMEL
MCU is available.
