BlueMod+C11/G2 Hardware Reference 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.
BlueMod+C11/G2 Hardware Reference 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.
BlueMod+C11/G2 Hardware Reference 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.

BlueMod+C11/G2 Hardware Reference 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 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.
BlueMod+C11/G2 Hardware Reference 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 transmitter 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.
BlueMod+C11/G2 Hardware Reference 3.6.4 Analog to Digital Converter Three ADC channels with 8 to 10bit resolution in reference to 1.8V are available.

BlueMod+C11/G2 Hardware Reference 6.5 Housing Guidelines The individual case must be checked to decide whether a specific housing is suitable for the use of the internal antenna. A plastic housing must at least fulfill the following requirements: Non-conductive material, non-RF-blocking plastics No metallic coating ABS is suggested www.stollmann.
BlueMod+C11/G2 Hardware Reference 6.6 Antenna Issues BlueMod+C11/G2 is shipped with 3 different antenna designs: BlueMod+C11/G2/-AI comprises a ceramic antenna which as a component is soldered to the circuit board. This is functional for a BlueMod+C11/G2/-AI integrated into a plastic housing. No additional antenna is required. For an external antenna to be set in, e.g.
BlueMod+C11/G2 Hardware Reference To give an optimized antenna performance the restricted area having no ground or power planes, traces or parts should be widened. The following dimensions should be implemented, depending on your possible space. Optimal placement The best position to place the BlueMod+C11/G2 on the target PCB is in the upper right corner. This position is optimal concerning antenna interference; radiation pattern and PCB space that has to be keep free for the restricted area.
BlueMod+C11/G2 Hardware Reference When placing the BlueMod+C11/G2 at the right edge of the PCB ensure that the restricted area on the target PCB is free of planes, traces and parts. acceptable, but not optimal placement When placing the BlueMod+C11/G2 on other positions than the right side the complete restricted area should be kept free of planes, traces and parts. 6.
