BlueMod+S/AI Hardware Reference 3 Application Interface 3.1 Power Supply BlueMod+S require a power supply with the following characteristics: Typical: 3,0VDC, min.: 1,8VDC, max.: 3,6VDC, thereby delivering > 25 mA peak BlueMod+S is designed to be powered from 3V coin cell batteries e.g. CR2032 directly, or any other power source complying with the given requirements. For optimal performance a stable supply is recommended. BlueMod+S XC6204B-3.
BlueMod+S/AI Hardware Reference 3.3 Reset BlueMod+S are equipped with circuitry for generating power-up reset from the supply voltage VSUP, as well as brownout detection. During power-up, reset is kept until the supply voltage VSUP has reached the minimal operating voltage. VSUP risetime has to comply with Table 1 for power-up reset to function properly. A reset is also generated when VSUP falls below the threshold of the brownout detector (1,6V ..
BlueMod+S/AI Hardware Reference The following table shows the pin states of BlueMod+S during reset active.
BlueMod+S/AI Hardware Reference 3.4 Serial Interface The serial interface of BlueMod+S is a high-speed UART interface supporting RTS/CTS flow control and interface-up/down mechanism according to the UICP+ protocol (refer to [3] ). Electrical interfacing is at CMOS levels (defined by VSUP; see chapter 5.5.1).
BlueMod+S/AI Hardware Reference 3.4.1 3-Wire Serial Interface When using only GND and UART-RXD, UART-TXD serial lines, leave UART-RTS# and UARTCTS# open. Note: It is strongly recommended to use hardware flow control. Not using flow control can cause a loss of data.

BlueMod+S/AI Hardware Reference 3.5 GPIO Interface It is possible to use the programmable digital I/Os GPIO[0:14] on the BlueMod+S. Their behavior has to be defined project specific in the firmware. Unused GPIO pins shall be left unconnected to stay compatible. There may be functions assigned to some in future versions of the firmware. 3.6 I2C Interface 1 The I2C bus interface serves as an interface between the internal microcontroller and the serial I2C bus.
BlueMod+S/AI Hardware Reference SPI Serial Peripheral Interface 2 3.7 The serial peripheral interface (SPI) allows for full-duplex, synchronous, serial communication with external devices. The interface can be configured as the master and then provides the communication clock (SCK) to the external slave device(s), or as the slave. The SPI Interface supports SPI-modes 0 through 3.
BlueMod+S/AI Hardware Reference 3.9 Slow Clock Interface Even though an external slow clock is not required for BLE operation, consumption of power during power-down modes can be reduced by feeding the module with an optional 32,768 kHz slow clock at pin XL-IN/SLCK, or connecting an XTAL (32,768kHz) and two capacitors C1, C2 at pins XL-IN and XL-OUT. 3.9.1 • • • 3.9.2 Symbol SLCK Specification (External Supplied Signal) 32,768 kHz +/-250ppm; duty cycle 30...70%.
BlueMod+S/AI Hardware Reference 3.9.3 Connection of an External 32,768 kHz Crystal Connect the 32,768 kHz crystal and two capacitors C1, C2 at pins A-6 (XL-IN/SLCK) and A-5 (XLOUT). The crystal has to comply with specifications given in Table 1. The exact value of C1 and C2 depends on the crystal and the stray capacitance of the layout. Select C1, C2 such that the slow clock oscillator operates at the exact frequency at room temperature (25°C).
BlueMod+S/AI 3.11 Operating in a Power-Switched Environment A potential "back feeding" problem may arise, if the module is operated in an environment where its power supply (VSUP) is switched off by the application. This might be done to save some power in times Bluetooth is not needed. As stated in Table 7, the voltage on any I/O pin must not exceed VSUP by more than 0,3V at any time. Otherwise some current IINJ flows through the internal protection diodes.

BlueMod+S/AI 6.4 Placement Recommendation To achieve best radio performance for BlueMod+S/AI, it is recommended to use the placement shown in Figure 17. This is a “corner placement” meaning the BlueMod+S/AI is placed such that the antenna comes close to the corner of the application PCB (red area). So, the yellow area is outside the PCB and regards to the housing, too (refer to 6.5).

BlueMod+S/AI 7 Application Diagram The following schematic shows a typical application of BlueMod+S. The module is connected to some MCU running the application layer. MCU and BlueMod+S use the same 3,3V power supply. The serial interface has RTS/CTS flow control and UICP support in this example. The optional hangup feature to close down the link is provided. As an option to save power, there is an external slow clock oscillator. All other module pins may be left unconnected.
