This document describes operation of STM 300x modules with their built-in firmware. If you want to write own firmware running on the integrated micro controller or need more de-tailed information on the Dolphin core please also refer to:  Dolphin Core Description  Dolphin API Documentation In addition we recommend following our application notes, in particular:  AN102: Antenna Basics – Basic Antenna Design Considerations for EnOcean based Products  AN105: 315 MHZ Internal Antenna Design – Considerations for EnOcean based Products  AN207: ECS 300/310 Solar Panel - Design Considerations  AN208: Energy Storage – Design Considerations  AN209: STM 300 THERMO OR BATTERY POWERED – Power Supply Alternatives to Solar Panel 2 GENERAL DESCRIPTION 2.1 Basic functionality The extremely power saving RF transmitter module STM 300 of EnOcean enables the realization of wireless and maintenance free sensors and actuators such as room operating panels, motion sensors or valve actuators for heating control. Power supply is provided by an external energy harvester, e.g. a small solar cell (e.g. EnOcean ECS 3x0) or a thermal har-vester. An energy storage device can be connected externally to bridge periods with no supply from the energy harvester. A
USER MANUAL 1.34 © 2013 EnOcean | www.enocean.com STM 300 / STM 300C / STM 300U User Manual | Page 5/41 STM 300 / STM 300C / STM 300U voltage limiter avoids damaging of the module when the supply from the energy harvester gets too high. The module provides a user configurable cyclic wake up. After wake up a radio telegram (input data, unique 32 bit sensor ID, checksum) will be transmitted in case of a change of any digital input value compared to the last sending or in case of a signifi-cant change of measured analogue values (different input sensitivities can be selected). In case of no relevant input change a redundant retransmission signal is sent after a user con-figurable number of wake-ups to announce all current values. In addition a wake up can be triggered externally.

Therefore an interface supply voltage pin IOVDD is available which can be connected either to DVDD or to an external supply within the tolerated volt-age range of IOVDD. Please note that the wristwatch XTAL I/Os WXIDIO and WXODIO are always supplied from UVDD. If DVDD=0 V (e.g. in any sleep mode or if VDD<VOFF) and IOVDD is supplied, there may be unpredictable and varying current from IOVDD caused by internal floating nodes. It must be taken care that the current into IOVDD does not exceed 10 mA while DVDD=0 V. If DVDD=0 V and IOVDD is not supplied, do not apply voltage to any above men-tioned pin. This may lead to unpredictable malfunction of the device. For I/O pins configured as analog pins the IOVDD voltage level is not relevant! However it is important to connect IOVDD to a supply voltage as specified in 3.5. IOVDDADIO0ADIO1ADIO2ADIO3ADIO4ADIO5ADIO6ADIO7SCSEDIO0SCLKDIO1WSDADIO2RSDADIO3If configured as digital I/O

Gain Error: Describes the offset between maximum possible code and full scale (e.g. 0x3FF for 10 bit measurements). Integral Non-Linearity (INL): Describes the difference between the ideal characteristics and the real characteristics. Only values between minimum and maximum possible code are considered (excluding offset error and gain error). Differential Non-Linearity (DNL): Measures the maximum deviation from the ideal step size of 1 LSB (least significant bit). Effective resolution: Results from the signal-noise ratio of the ADC and is given in Bit. The number describes how many bits can be measured stable. The criterion selected here is that the noise of DNL is <±0.5 LSB. Measurement Bandwidth: The measurement bandwitdh is internally limited by filters. A quasi static signal must be applied as long as the filter needs to settle. SettlingTime= 1/(MeasurementBandwidth)*ln(2^resolution[Bit]) For further details please refer to the Dolphin Core Description. 1 3 dB input bandwidth, resulting in 111 µs settling time to achieve a deviation of an input signal <1 LSB (<0.098% @ 10 bit resolution).

Threshold detector STM 300 provides an ultra low power ON/OFF threshold detector. If VDD > VON, it turns on the ultra low power regulator (UVDD), the watchdog timer and the WAKE# pins circuitry. If VDD ≤ VOFF it initiates the automatic shut down of STM 300. 3.7 Charge control output (CCO) After start-up STM 300 provides the output signal of the threshold detector at CCO. CCO is supplied by UVDD. The output value remains stable also when STM 300 is in deep sleep mode.

After transmission the counter is reset to a random value within the specified in-terval. According to FCC 15.231a) a redundant retransmission at every timer wake-up to determine the system integrity is only allowed in safety and security applications! In this case the total transmission time must not exceed two seconds per hour, which means that a combination with a 1 s wake-up cycle time is not allowed! If applied in other (non-safety, non-security) applications a minimum of 10 s be-tween periodic transmissions is required. In addition the device has to comply with the lower field strength limits of 15.231e). The limited modular approval of STM 300C is not valid in this case.

With each transmission cycle, 3 identical subtelegrams are transmitted within 40 ms. Transmission of a subtelegram lasts approximately 1.2 ms. The delay time between the three transmission bursts is affected at random. If a new wake-up occurs before all sub-telegrams have been sent, the series of transmissions is stopped and a new series of telegrams with new valid measure-ment values is transmitted.

In order to support a fast start-up and long term operation with no energy supply available usually two different storages are used. The small storage fills quickly and allows a fast start-up. The large storage fills slowly but once it is filled up it provides a large buffer for times where no energy is available, e.g. at night in a solar powered sensor. STM 300 provides a digital output CCO (see also 3.7) which allows controlling the charging of these two storages. At the beginning, as long as the voltage is below the VON voltage only the small storage is filled. Once the threshold is reached the CCO signal changes and the large storage is filled. The short term storage capacitor (C1) is usually in the range of 470 to 1000 µF. For the long term storage we suggest a capacitor (C2) with a capacity of 0.25 F. Below an overview and the schematics of a charging circuitry is shown: This circuit is designed for an energy storage capacitor specified for 3.3 V (e.g. PAS614L-VL3. Please pay great attention to manufacturers handling and soldering procedures!) C1 C2

Supposing VDD then falls below VON, the energy source will be switched back to short term storage alone, for faster recharging. As long as the voltage on long term storage remains below VON, the charge switcher will continuously switch the energy source be-tween short term and long term storage, trying to ensure continuous device operation. That is because of the higher resistance and capacitance of long term storage, which would lead to much too long charging (i.e. non-operative time). In addition short term storage cannot be charged over this threshold until the voltage on long term storage exceeds VON. Charge switcher is the PMOS transistor Q1, driven from the STM 300 charge control output CCO over T1A. To start with, as long as the STM 300 VDD voltage is below the VON threshold, only the small storage (C1) is filled over D3. Once the threshold is reached, the CCO control signal goes High, T1B and Q2 are turned on and the long term storage (C2) will be filled over Q2. Overvoltage protection All of these long term storage solutions have a rated operating voltage that must be not exceeded. After reaching this limit the energy source is automatically separated from stor-age to avoid any damage. Overvoltage protection is implemented by the S-1000C32-M5T1x voltage detector from Seiko (SII) or the NCP300LSN30T1G series (ON Semiconductor), which limits the maximum charging voltage to 3.3 V to avoid damaging long term energy storage. In case a different voltage limit is required, this device has to be replaced by a suitable voltage variant. As soon as the voltage on D2 anode or the voltage detector input exceeds the selected threshold, the voltage detector delivers a High level on its output con-nected to the T1A emitter. The T1A base is consequently lower polarized than its emitter and the transistor is turned off. That means Q1 is turned off too — the energy source is switched off and long term storage is protected. The selected voltage detector must have a very low quiescent current in the operating range, and an appropriate threshold voltage, corresponding to the selected long term ener-gy storage voltage (e.g. threshold nominally 3.2 V for a 3.3 V capacitor). If the selected threshold is too low, e.g. 3.0 V, a relatively high amount of energy corresponding to a use-ful voltage difference of 0.3 V would be wasted. If the nominal threshold is too high, e.g. exactly 3.3 V (not forgetting that this could reach 3.4 V as a result of additional manufac-turer tolerances), it could be critical for energy storage life expectation. The S-1000C32-M5T1x voltage detector consequently looks like the best compromise here (rated 3.2 V) Undervoltage protection PAS capacitors should not be deep discharged to voltages below 1.5 V. To avoid long term degradation of their capacity and lifetime, an undervoltage protection block is added. Undervoltage protection is also implemented through Q2. In normal operation, when VDD reaches the VON threshold, the STM 300 charge control CCO goes high, T1B rapidly dis-charges C3 to GND and Q2 turns on long term storage. The C3 charge recovers very slowly over R6, so Q2 cannot turn off long term storage immediately. Only if VDD falls below VOFF for a longer time does C3 have time to recover and finally to turn off Q2 and thus the long term storage path (over D4) from the STM 300, avoiding deep discharge. For more details and alternative circuits please refer to application note AN208.

This helps saving energy as the sensor circuitry is only powered as long as necessary. In the default configuration SCO provides a HIGH signal 2 ms (delay time) be-fore the analog inputs are read. Via the programming interface (see 3.8.2) it is possible to adjust the delay time and also the polarity of the signal. The figure above shows, how the SCO pin (with default polarity) can be used to control an external sensor circuit. Do not supply sensors directly from SCO as this output can only provide maximum 15 µA! 4.3 Using the WAKE pins The logic input circuits of the WAKE0 and WAKE1 pins are supplied by UVDD and therefore also usable in “Deep Sleep Mode” or “Flywheel Sleep Mode” (via API only). Due to current minimization there is no internal pull-up or pull-down at the WAKE pins. When STM 300 is in “Deep Sleep Mode” or “Flywheel Sleep Mode” (via API only) and the logic levels of WAKE0 and / or WAKE1 is changed, STM 300 starts up. As the there is no internal pull-up or pull-down at the WAKE pins, it has to be en-sured by external circuitry, that the WAKE pins are at a defined logic level at any time. When using the UVDD regulator output as source for the logic HIGH of the WAKE pins, it is strongly recommended to protect the ultra low power UVDD voltage regulator against (accidental) excessive loading by connection of an external 1.8 MΩ series resistor.

When the LRN button is pressed WAKE1 is pulled to GND and a teach-in telegram is transmitted. As long as the button is pressed a small current is flowing from UVDD to GND. WAKE0 is connected to a toggle switch. There is no continuous flow of current in either po-sition of the switch. If more digital inputs with WAKE functionality are needed in an application, WAKE0 can be combined with some of the digital inputs as shown below: 4.4 Using RVDD If RVDD is used in an application circuit a serial ferrite bead shall be used and wire length should be as short as possible (<3 cm). The following ferrite beads have been tested: 74279266 (0603), 74279205 (0805) from Würth Elektronik. During radio transmission and reception only small currents may be drawn (I<100 µA). Pulsed current drawn from RVDD has to be avoided. If pulsed currents are necessary, suffi-cient blocking has to be provided.

Please refer to our application notes AN102, and AN105 which give an overview on our recommendations. All STM300x modules have been approved with whip antenna, and STM 300U with helical antenna in addition. 868.300 MHz modules used in Europe do not need additional approval if the external an-tenna fulfils the following requirements: Frequency band 868.300 MHz ISM Antenna must be suited for this band Antenna type Passive Mandatory for radio approval Impedance ~50 Ohm Mandatory for radio approval Maximum gain ≤ 0 dBd Mandatory for radio approval In addition it is important to fulfill the following requirements in order to achieve compati-bility with other EnOcean products and to ensure excellent EMI robustness: VSWR ≤ 3:1 Important for compatibility with EnOcean protocol Return Loss > 6 dB Important for compatibility with EnOcean protocol Bandwidth ≤ 20 MHz Important if 10 V/m EMI robustness required for device For 315 MHz / 902.875 MHz modules (STM 300C / STM 300U) please note that a full approval is needed if modules are used with antennas other than the specified antennas. 4.5.2 Whip antenna 315 MHz Antenna: 150 mm wire, connect to RF_WHIP Minimum GND plane: 50 mm x 50 mm Minimum distance space: 10 mm 868.3 MHz Antenna: 86 mm wire, connect to RF_WHIP Minimum GND plane: 38 mm x 18 mm Minimum distance space: 10 mm 902.875 MHz Antenna: 64 mm wire, connect to RF_WHIP Minimum GND plane: 50 mm x 50 mm Minimum distance space: 10 mm

For good receiver performance, great care must be taken about the space immediately around the antenna since this has a strong influence on screening and detuning the an-tenna. The antenna should be drawn out as far as possible and must never be cut off. Mainly the far end of the wire should be mounted as far away as possible (at least 15 mm) from all metal parts, ground planes, PCB strip lines and fast logic components (e.g. micro-processors). Do not roll up or twist the whip antenna! Radio frequency hash from the motherboard desensitizes the receiver. Therefore:  PCB strip lines on the user board should be designed as short as possible  A PCB ground plane layer with sufficient ground vias is strongly recommended  See also section Fehler! Verweisquelle konnte nicht gefunden werden. for power supply requirements. Problems may especially occur with switching power supplies!

It is recommended to have a complete GND layer in the application PCB, at least in the area below the module and directly connected components (e.g. mid-layer of your application PCB). Due to unisolated test points there are live signals accessible on the bottom side of the module. Please follow the following advices to prevent interference with your application circuit:  We suggest avoiding any copper structure in the area directly underneath the module (top-layer layout of your application PCB). If this is not possible in your design, please provide coating on top of your PCB to prevent short circuits to the module. All bare metal surfaces including vias have to be covered (e.g. adequate layout of solder resist).  It is mandatory that the area marked by the circle in the figure below is kept clear of any conductive structures in the top layer and 0.3 mm below. Otherwise RF performance will be degraded! Furthermore, any distortive signals (e.g. bus signals or power lines) should not be routed underneath the module. If such signals are present in your design, we sug-gest separating them by using a ground plane between module and these signal lines. The RVDD line should be kept as short as possible. Please consider recommenda-tions in section 4.4.

In order to ensure good solder quality a solder mask thickness of 150 µm is recommended. In case a 120 µm solder mask is used, it is recommended to enlarge the solder print. The pads on the solder print should then be 0.1 mm larger than the pad dimensions of the module as specified in chapter 2.3. (not relative to the above drawing). Nevertheless an application and production specific test regarding the amount of soldering paste should be performed to find optimum parameters.

STM 300 shall be handled according to Moisture Sensitivity Level MSL4 which means a floor time of 72 h. STM 300 may be soldered only once, since one time is already consumed at production of the module itself. Once the dry pack bag is opened, the desired quantity of units should be removed and the bag resealed within two hours. If the bag is left open longer than 30 minutes the desiccant should be replaced with dry desiccant. If devices have exceeded the specified floor life time of 72 h, they may be baked according IPC/JEDEC J-STD-033B at max. 90°C for less than 60 h. Devices packaged in moisture-proof packaging should be stored in ambient conditions not exceeding temperatures of 40 °C or humidity levels of 90% r.h. STM 300 modules have to be soldered within 6 months after delivery!

Since the expected transmission range strongly depends on this system conditions, range tests should categorically be performed before notification of a particular range that will be attainable by a certain application. The following figures for expected transmission range are considered by using a PTM, a STM or a TCM radio transmitter device and the TCM radio receiver device with preinstalled whip antenna and may be used as a rough guide only:  Line-of-sight connections: Typically 30 m range in corridors, up to 100 m in halls  Plasterboard walls / dry wood: Typically 30 m range, through max. 5 walls  Line-of-sight connections: Typically 30 m range in corridors, up to 100 m in halls  Ferroconcrete walls / ceilings: Typically 10 m range, through max. 1 ceiling  Fire-safety walls, elevator shafts, staircases and supply areas should be considered as screening. The angle at which the transmitted signal hits the wall is very important. The effective wall thickness – and with it the signal attenuation – varies according to this angle. Signals should be transmitted as directly as possible through the wall. Wall niches should be avoid-ed. Other factors restricting transmission range:  Switch mounted on metal surfaces (up to 30% loss of transmission range)  Hollow lightweight walls filled with insulating wool on metal foil  False ceilings with panels of metal or carbon fiber  Lead glass or glass with metal coating, steel furniture The distance between EnOcean receivers and other transmitting devices such as comput-ers, audio and video equipment that also emit high-frequency signals should be at least 0.5 m A summarized application note to determine the transmission range within buildings is available as download from www.enocean.com.

The module is optimized to operate using small amounts of energy, and may be powered by a battery. The module transmits short radio packets comprised of control signals, (in some cases the control signal may be accompanied with data) such as those used with alarm sys-tems, door openers, remote switches, and the like. The module does not support continu-ous streaming of voice, video, or any other forms of streaming data; it sends only short packets containing control signals and possibly data. The module is designed to comply with, has been tested according to 15.231(a-c), and has been found to comply with each requirement. Thus, a finished device containing the STM 300C or the STM 300U radio mod-ule can be operated in the United States without additional Part 15 FCC approval (ap-proval(s) for unintentional radiators may be required for the OEM’s finished product), under EnOcean’s FCC ID number. This greatly simplifies and shortens the design cycle and devel-opment costs for OEM integrators. The module can be triggered manually or automatically, which cases are described below. Manual Activation The radio module can be configured to transmit a short packetized control signal if trig-gered manually. The module can be triggered, by pressing a switch, for example. The packet contains one (or more) control signals that is(are) intended to control some-thing at the receiving end. The packet may also contain data. Depending on how much en-ergy is available from the energy source, subsequent manual triggers can initiate the transmission of additional control signals. This may be necessary if prior packet(s) was(were) lost to fading or interference. Subsequent triggers can also be initiated as a pre-caution if any doubt exists that the first packet didn’t arrive at the receiver. Each packet that is transmitted, regardless of whether it was the first one or a subsequent one, will only be transmitted if enough energy is available from the energy source. Automatic Activation The radio module also can be configured to transmit a short packetized control signal if triggered automatically, by a relevant change of its inputs or in response to receiving a signal from another transmitter, for example. Again, the packet contains a control signal that is intended to control something at the receiving end and may also contain data. As above, it is possible for the packet to get lost and never reach the receiver. However, if enough energy is available from the energy source, and the module has been configured to do so, then another packet or packets containing the control signal may be transmitted at a later time. The device is capable to operate as a repeater, which can receive signals from the following list of FCC/IC approved transmitters, and retransmit the signals.
