Page 14: Gpio Supply Voltage
STM 431J – Scavenger Transmitter Module 2.3.1 GPIO supply voltage The IOVDD pin of Dolphin V4 is internally connected to DVDD. For digital communication with other circuitry therefore a voltage of 1.8 V has to be used. While the module is in deep sleep mode the microcontroller with all its peripherals is switched off and DVDD, IOVDD, and SWPWR are not supplied. -
Page 15: Temperature Sensor
If VDD is not accessible, e.g. because the module shall be programmed via the pin con- nector, please use VCHAR instead of VDD (see 0). © 2017 EnOcean | www.enocean.com STM 431J User Manual | v2.0 | Nov 2017 | Page 15/ 34... -

Page 22: Encrypted Communication - Enhanced Security Mode
Therefore mode change is limited to 50 times. In normal application scenario only very few are required. The factory delivery mode of the STM 431J is standard – not encrypted. This mode is com- mon mode originally available. Secure mode was added in later product upgrades. -

Within each transmission cycle, 3 identical subtelegrams are transmitted within 40 ms. The transmission of one subtelegram lasts approximately 1.2 ms. The delay between the three subtelegram transmissions is random. © 2017 EnOcean | www.enocean.com STM 431J User Manual | v2.0 | Nov 2017 | Page 23/ 34... -
Page 24: Charging Circuitry
The figure below shows the internal charging circuit. It is controlled via the WXODIO pin of Dolphin V4 which switches according to the status of the internal threshold detector. For details please refer to the Dolphin V4 Core Description documentation. The WXIDIO pin is used to disconnect the energy storage element at voltages below VOFF to avoid deep dis- charge. - Page 25 Pre-installed solar cell ECS 300, operating values 3 V and 5 µA @ 200 lux fluorescent light Current proportional to illumination level (not true at very low levels!) © 2017 EnOcean | www.enocean.com STM 431J User Manual | v2.0 | Nov 2017 | Page 25/ 34...

“Deep Sleep Mode”. Due to current minimization there is no internal pull-up or pull-down at the WAKE pins. When STM 431J is in “Deep Sleep Mode” and the logic lev- els of WAKE0 and / or WAKE1 is changed, STM 431J starts up. -
