PTM 535BZ – BLUETOOTH AND ZIGBEE GREEN POWER PUSHBUTTON TRANSMITTER

2.3.1 Key components

PTM 535BZ uses the following main components to achieve the desired product functionality:

ECO 200 energy harvester

Converts the kinetic energy (press / release) into electrical energy and is used to power PTM

535BZ in self-powered applications. Alternatively, a power supply might be used.

Power management

Converts the energy of the power generator into a stable supply voltage suitable to power

the device electronics. It also determines the polarity of the input voltage which allows

identifying the direction of the ECO 200 action (press or release).

Data processing

Determines the status of the external inputs and the ECO 200 action, encodes this status

into a data word, calculates the unique security signature, generates the proper radio

telegram structure and sends it to the 2.4 GHz BLE / Zigbee radio transmitter

2.4 GHz BLE / Zigbee radio transmitter

Transmits the data in the form of a series of short 2.4 GHz Bluetooth Low Energy (BLE) or

Zigbee Green Power (ZGP) radio telegrams using the integrated antenna

NFC configuration interface

Allows reading and writing certain product parameters using an NFC compliant reader / writer

supporting NFC Forum tags (as specified by ISO/IEC 15693).
