The LC87F7932B realises 0.45 μA average power consumption in RTC mode, and 1.5 μA total average power consumption while controlling LCD display, RTC operation, while a 12-bit ADC intermittently operates for temperature measurement. Particular features of this design platform include a universal harvesting interface block able to collect energy from piezo-electric benders, solar cells, thermoelectric generators (with mV range boost). A maximum power point tracking (MPPT) architecture permits to implement sophisticated and specific algorithm to optimize power transfer. Whatever storage element is selected (supercap, rechargeable battery, capacitor, solid state battery), the ETA platform will store energy in it and monitor the charge process. Digital IOs are available to interface with external circuitry. Programmable PWM generators can drive relays or industrial actuators. Wake-up pins can be configured to generate interrupts or complex actions. Each block has been designed to be programmable by an external microcontroller. An internal activity manager can perform specific tasks in a time base or in case of specific events. It can generate alarms or cascade other programmed actions. The development tool along with all documentation and datasheets are available off-the-shelf to shorten overall development time and enable highly creative concept validation for industry automation, building automation, health care and other applications. Canova Technology www.canovatech.com Energy harvesting wireless switch transmits on-off data over a 300m range at 868MHz The energy harvesting wireless switch offered by Cherry Corporation comes as a 25x9.4x23.9mm unit that communicates its switching status wirelessly over the 868MHz or 2.4GHz RF band. The switch does not require complex wire assembly and RF transmission is powered by the mechanical actuation of the switch (8N and a total travel of 3.4mm generating two times 0.2 up to 0.5mW), which means that no batteries need to be changed or disposed. With a Lifetime up to 1.000.000 operations and rated for operation in the -40 to +85°C temperature range, each switch comes with a unique ID that excludes mutual interference between different RF-switches. Flexible pairing allows the operation of several receivers with one switch (and vice versa). The wireless range is 10m at 2.4GHz and over 300m at 868MHz (line of sight).
