APPLICATION INTERFACE Power Supply BlueMod+S50 require a power supply with the following characteristics: Typical: 3,0VDC, min.: 1,7VDC, max.: 3,6VDC, thereby delivering > 25 mA peak BlueMod+S50 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. Furthermore, it is recommended to place a capacitor in parallel to the CR2032 3V coin cell battery in order to prolong battery lifetime, by compensating the effects of the rising source resistance of the battery to pulsed loads. Since the isolation resistance of this capacitor will discharge the battery in a not insignificant scale, the capacitor should be chosen under consideration of the following rules: ⢠⢠⢠⢠capacitance as small as necessary nominal voltage as high as possible case size as large as possible use X7R instead of X5R BlueMod+S50 XC6209F-3.3 VSUP E-6,F-6 5 VOUT VSS VIN 1 +5VDC CE 3 1Âľ 1Âľ + 100n GND: A-7,E-7,F-7,B-[5:8], C-[5:8],D-8,E-8,F-8 Figure 3: BlueMod+S50 Example Power Supply with LDO It is strongly recommended NOT to switch the module power supply on/off while other parts of the circuitry stay powered. This mostly leads to hardly controllable back-feeding issues. Due to the ultra-low power design a few ÂľAmps are enough to raise VSUP to an undefined state, which may cause a hang-up deadlock if power is switched on again. Any I/O pin at a voltage > 0,3V while the supply VSUP is at 0V violates the abs. max. ratings given in chapter 5.1 Absolute Maximum Ratings. It is instead recommended to use the advanced power management features, which may reduce the supply current to 300nA. 1VV0301505 Rev. 1 Page 13 of 53 2018-03-02 BlueMod+S50 Hardware User Guide Reset BlueMod+S50 are equipped with circuitry for generating reset from two sources: ⢠A reset is held active, when VSUP falls below the threshold of the brownout detector (VBOR = 1,2V ⌠1,7V), and is released when VSUP rises above VBOR + VHYST . The brownout detector also holds the reset active during power up, until VSUP > VBOR. ⢠A reset is generated, when VSUP is > VBOR and increases 300 mV or more, within 300 ms or less. ⢠By holding pin B-1 (EXT-RES#) at ⤠VSUP*0,25V for tHOLDRESETNORMAL ⼠0,2Âľs, an external reset (pin reset) is generated. This pin has a fixed internal pull-up resistor (RPU = 11kΊ ... 16kΊ). EXT-RES# may be left open if not used. Host MCU BlueMod+S50 +3V3 VSUP EXT-RES# E-6,F-6 VDD B-1 GPIO Reset signal is optional GND Reset-Switch is optional Please Note: EXT-RES# of BlueMod+S50 has approx. 13k internal pullup. Figure 4: BlueMod+S50 Example Reset The following table shows the pin states of BlueMod+S50 during reset active. This pin states are kept until hardware initialization has started.

See corresponding AT command reference [3] for further information. 4.3.1. Basic Serial Interface The basic serial interface (with RTS/CTS flow control) uses only four signal lines (UARTRXD, UART-TXD, UART-CTS#, UART-RTS#) and GND. IUR-IN# and IUR-OUT# (see below) can be left unconnected. UART-RXD BlueMod+S50 Host UART-TXD UART-CTS# UART-RTS# GND Figure 5: Basic Serial Interface A pulldown resistor is programmed to CTS# if UICP is disabled. If AT+SYSTEMOFF is issued while UICP is disabled, it is necessary that the host keeps CTS# at logic low or leaves this pin floating. Otherwise the supply current drawn in the deep sleep mode increases by VSUP/13kâŚ, which would be at 3V 231ÂľA, 770 times the expected 0,3ÂľA. This would reduce the life time of a coin cell significantly. 1VV0301505 Rev. 1 Page 15 of 53 2018-03-02 BlueMod+S50 Hardware User Guide 4.3.2. 4-Wire Serial Interface If the host in question is sufficiently fast, a four-wire scheme may be successful. Connect the serial lines UART-RXD, UART-TXD as well as UART-RTS# and GND; leave UARTCTS# open. The host is required to stop sending data within a short time after de-assertion of UART-RTS# (there is room for up to 4 more characters at the time RTS# drops). UART-TXD UART-RXD UART-RXD UART-TXD CTS# IUC_OUT# / RTS# IUC_IN# / CTS# IUR_OUT# IUR_IN# GND Figure 6: UART Interface without UICP Signals 4-wire (incl. GND) UICP has to be deactivated permanently in this configuration, because signal UART-CTS# and IUR-IN# become inputs with no PU or PD if UICP is active. This would cause floating CMOS inputs. It is strongly recommended to use hardware flow control in both directions. Not using flow control can cause a loss of data. 4.3.3. Serial Interface with UICP UART-TXD UART-RXD UART-RXD UART-TXD RTS# CTS# CTS# RTS# IUR_IN# / DTR IUR_OUT# IUR_IN# Host BlueMod+Sx A substantially saving of power during idle phases can be achieved (see when the UICP protocol is used (refer to [2]). This protocol should be implemented on the host side as well. Signals IUR-IN# and IUR-OUT# should be connected to the host and may be mapped to DSR and DTR, if an RS232-style (DTE-type) interface is used (see Figure 7). IUR_OUT# / DTS GND Figure 7: BlueMod+S50 Serial Interface Supporting UICP 1VV0301505 Rev. 1 Page 16 of 53 2018-03-02 BlueMod+S50 Hardware User Guide If I/O line availability at the host side is extremely tight, 2 I/O lines could be saved by using the following scheme. This would come at the cost of ⢠⢠BlueMod+Sx ⢠UART-TXD UART-RXD UART-RXD UART-TXD IUC_OUT# / RTS# CTS# IUC_IN# / CTS# RTS# IUR_OUT# Host The host is not allowed to enter sleep mode. The host must accept incoming data at all times and is not able to stop the BlueMod+Sx sending data. This may be difficult to control for all scenarios and adds the risk that data gets lost. The host doesnât implement UICP, but wake-up BT via GPIO. BM+Sx-WKUP IUR_IN# GND Figure 8: Five Wire Interface supporting UICP 4.3.4. Dynamic I/O Signal Type Changes Depending on UICP Status In order to reduce current consumption when using UICP, the BlueMod+S50 FW supports the following dynamic I/O signal type changes depending on the UICP activated resp. deactivated status. Signal UICP deactivated UICP activated UART-CTS# I-PD I-FLOAT IUR-IN# I-DIS I-FLOAT IUR-OUT# I-DIS O-PP (1) I-PU: input pull-up; I-PD: input pull-down; I-FLOAT: input floating; I-DIS: input disconnected; O-PP: output push-pull Table 2: Pin Assignments Signal types I-PD, I-DIS and O-PP may be left open. I-FLOAT has to be driven to GND or VCC to avoid open CMOS input oscillation. If UICP is deactivated the pull-down resistor on UART-CTS# helps to keep the serial interface active if UART-CTS# is open. If UICP is active and the serial interface is down, UART-CTS# has to be held at VCC and thus the pull-down would cause an unwanted permanent current drain. Therefore, the pulldown is switched off in this mode. 1VV0301505 Rev. 1 Page 17 of 53 2018-03-02 BlueMod+S50 Hardware User Guide 4.3.5.

It is possible to use the programmable digital I/Os GPIO[0:14] on the BlueMod+S50. Unused GPIO pins shall be left unconnected to stay compatible. There may be functions assigned to some in future versions of the firmware. Refer to 5.3 I2C Interface Functionality is defined project specific in the firmware used. The I2C bus interface serves as an interface between the internal microcontroller and the serial I2C bus. BlueMod+S50 is the master and controls all I2C bus specific sequencing, protocol and timing. It supports standard (100kHz) and fast (400kHz) speed modes. The BlueMod+S50 as an I2C master must be the only master of the I2C bus (no multimaster capability). Clock stretching is supported. SDA and SCL can be used to form an I2C interface. It is required to connect 4k7 pull-up resistors on SCL and SDA when this interface is used.

It is reserved for debugging purposes. Leave SWDIO, SWCLK unconnected. Only if you intend to use them for debugging purposes, make them available. Test Mode For regulatory approval purposes, the ability of test mode operation like âBlueMod+S50 Testmodeâ or âDirect two wire UART Testmodeâ (DTM) is mandatory. The Direct Test Mode (as defined by the Bluetooth SIG) and BlueMod+S50 Testmode are part of the BlueMod+S50 firmware. Please refer to [6] & [7]. For enabling the different test modes the BlueMod+S50 provides two IO pins. ⢠⢠⢠The pin Testmode is low active. Active means connect to GND. The pin Boot0 is high active. Active means connect to VSUP. The other two combinations start the bootloader for firmware update of the programmed firmware. These two modes are not scope of this document. Table 3 shows the possible combinations: Testmode# Boot0 Mode Active Inactive Testmode Active Active DTM Inactive Active Bootloader Inactive Inactive Firmware Table 3: Testmode# / Boot0 Logic To enter and use the test modes, access to the following signals is required: ⢠⢠⢠⢠⢠⢠⢠BOOT0 TESTMODE# UART-RXD UART-TXD UART-RTS# UART-CTS# GND These pins shall be routed to some test pads on an outer layer, but can be left open during normal operation when not used. Please note the UART is required for operation of DTM. For any regulatory approval, UART-RXD, UART-TXD, UART-RTS# and UART-CTS# must be freely accessible. 1VV0301505 Rev. 1 Page 20 of 53 2018-03-02 BlueMod+S50 Hardware User Guide NFC Function Functionality is defined project specific in the firmware used. The NFCT peripheral supports communication signal interface type A and 106 kbps bit rate from the NFC Forum. With appropriate software, the NFC peripheral can be used to emulate the listening device NFC-A as specified by the NFC Forum. Main features for the NFC peripheral: ⢠⢠⢠⢠⢠⢠⢠NFC-A listen mode operation 13.56 MHz input frequency Bit rate 106 kbps Wake-on-field low power field detection (SENSE) mode Frame assemble and disassemble for the NFC-A frames Programmable frame timing controller Integrated automatic collision resolution, CRC and parity functions 4.9.1. NFCT Antenna Recommendations The NFCT antenna coil must be connected differential between NFCANT1 and NFCANT2 pins of BlueMod+S50. Two external capacitors Ctune1/2 connected between the NFCANTx pins and GND should be used to tune the resonance of the antenna circuit to 13.56 MHz.

That means, current may flow in the opposite direction on the supply due to parasitic diodes and ESD structures. If a battery is used that does not tolerate return current, a series diode must be placed between the battery and the BlueMod+S50 in order to protect the battery. An ultra-low forward voltage schottky diode should be chosen to keep the battery life reduction as small as possible. 1VV0301505 Rev. 1 Page 21 of 53 2018-03-02 BlueMod+S50 Hardware User Guide 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 connecting an XTAL (32,768kHz) and two capacitors C1, C2 at pins XL-IN and XL-OUT.

In the sampling phase the capacitor CSAMPLE is charges to the analog source voltage for tACQ, by closing the TACQ switch for the acquisition time. In the conversion phase the TACQ is opened again and the voltage on CSAMPLE is converted to a digital value. Therefore FSAMPLE < 1/ (tACQ + tCONV) has to be maintained. The time necessary to load CSAMPLE with sufficient preciseness to VSOURCE depends on the values of CSAMPLE, known 2,5pF typ., and the source resistance of VSOURCE, e.g. a potentiometer.

The performance of the antenna has to be checked within the final integration environment. Adjacent PCBs, components, cables, housings etc. could otherwise influence the radiation pattern or be influenced by the radio wave energy. To achieve best radio performance for BlueMod+S50/AI, it is recommended to use the placement and layout shown in Figure 23 and Figure 24. This is a âcorner placementâ meaning the module 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 7.6). 20 Please note that for best possible performance the antenna should be directed away from the application PCB as shown in Figure 23. 17 4,5 max.0,5 15 10 40 max.0,5 10 no bare copper (exept solder pads for module) Applic.

For antenna port connection it is recommended to use a layout like shown in Figure 26. To keep specified radio power values the impedace of the RF trace connected to the antenna port shall be 50 Ohms. Impedace of the RF trace depends on customer pcb. Use a calculator for coplanar waveguides e.g. âTXlineâ to determine track width and gap between ground and RF track. Figure 25: coplanar waveguide sample Figure 26: AP antenna port layout recommendation OEM integrators are free with choosing a trace design suitable for their end product and selecting an antenna according to their needs. Only if it is desired to re-use the RED/FCC and IC certification of the BlueMod+S50/AP the following restrictions apply. 1) Use External Antenna: antenova part no B4844-R Please note that for FCC Certification it is mandatory to use a reverse SMA connector instead of using a standard SMA male connector on the antenna side. 2) Exactly follow the Trace Design with below given parameters The RF trace on the Telit standalone testboard used for homologation lab testing is placed on the top side of a standard FR4 4 layer PCB with Îľr â 4,7 and designed as microstrip transmission line with the below given parameters. In many cases the antenna is required to be mounted in another position on the end product. This could be achieved by using SMA/SMA coax cables. 1VV0301505 Rev. 1 Page 36 of 53 2018-03-02 BlueMod+S50 Hardware User Guide a. Trace Design Impedance 50R Calculation Figure 27: RF Trace Impedance Calculation Parameters b. Trace Design Geometry It is important to avoid coupling of noise from digital lines to the RF trace and also to avoid RF signal coupling into power supply or analogue lines. Therefore, the following RF trace design geometry has been successfully used on the Telit standalone testboard and should be followed by OEMâs re-using BlueMod+S50/AP RED/FCC or IC Certifications. Figure 28: RF Trace Design Geometry 1VV0301505 Rev. 1 Page 37 of 53 2018-03-02 BlueMod+S50 Hardware User Guide 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 Safety Guidelines According to SAR regulation EN 62479:2010 the BlueMod+S50/AI is not intended to be used in close proximity to the human body. Please refer to above-mentioned regulation for more specific information. In respect to the safety regulation EN 62368-1:2014 + AC:2015 all conductive parts of the BlueMod+S50 are to be classified as SELV circuitry. OEMâs implementing the BlueMod+S50 in their products should follow the isolation rules given in regulation EN 62368-1:2014. The PCB material of the BlueMod+S50 is classified UL-94V0. 1VV0301505 Rev. 1 Page 38 of 53 2018-03-02 BlueMod+S50 Hardware User Guide Cleaning In general, cleaning the modules mounted on the host board is strongly discouraged. Residues between module and host board cannot be easily removed with any cleaning method. ⢠⢠Cleaning with water or any organic solvent can lead to capillary effects where the cleaning solvent is absorbed into the gap between the module and the host board. The combination of soldering flux residues and encapsulated solvent could lead to short circuits between conductive parts. The solvent could also damage any labels. Ultrasonic cleaning could damage the module permanently. Especially for crystal oscillators the risk of damaging is very high. 8.

COMPLIANCES The BlueMod+S50/AI and BlueMod+S50/AP have been tested to fully comply with the appropriate EU, FCC and IC directives. CE testing is intended for end products only. Therefore, CE testing is not mandatory for a Bluetooth module sold to an OEM end product. However, Telit provides CE tested modules for customers in order to ease CE compliance assessment of end products and to minimize test effort. OEM end product compliance assessment has to be done for every end product by the OEMâs certification manager. It should be noted that compliance assessment doesnât necessarily mean re-testing in the test lab. Telt test reports are available on request and can be used to drastically reduce the test plan and compliance testing costs. All certifications and declarations, except RoHS and ReacH, are only valid for the BlueMod+S50 running with Telit FW. If the FLASH is erased and a customer specific FW is loaded all certifications have to be re-evaluated or renewed.
