With a data logger reference design based on the 64-Kbit Dual Interface EEPROM (M24LR64), a low power Microcontroller (STM8L101) and a digital temperature sensor (STTS75) you can develop your data logger quick and easy. It measures temperature, and offers an RF access to the data of the application thanks to the ISO15693 interface of the […]

Can you believe? RFID tranponder, EEPROM, temperature sensor, RTC, digital logic- all in one chip
This chip is real amazing, because it is all in one. You just need an RFID antenna, what could be a PCB track and a battery. The rest will be done by the logic inside. If temperature logging is not enough, then you can add external sensors interface. Right now there is a humunity sensor […]
Is this an EEPROM with RFID transponder or a RFID transponder with EEPROM?
The M24LR64 is an electrically-erasable memory (EEPROM) that can also be programmed wirelessly by industry standard RFID (radio-frequency ID) equipment. Using the M24LR64 for program or data storage provides extra flexibility for customers, allowing software updates or specific parameters to be applied in the supply chain. With an easy implementation based on two industry standard […]
Android, Linux, QNX, Symbian and Windows in M2M applications
I already started several projects on embedded Linux (GE863-Pro3 or UC864-G + BeagleBoard). One is for example a metering project for a customer in India. Development and manufacturing is provided by a business partner of mine in Germany. The next higher level is based on BeagleBoard http://www.beagleboard.org. The BeagleBoard is an open source single board […]
Bluetooth low energy is an “always off” technology. Basically it stays in the lowest power modes
Because power consumption is so low, coin cells will typically last a year or more. Bluetooth low energy chips can operate either as slaves or masters and which device takes what role is decided during the initial negotiation. There is no reason for a tag to be the proverbial one-trick pony. Design cycles will be short compared to proprietary solutions because the design team can concentrate its efforts on writing application layer code instead of the entire protocol stack. Sensing a means of making mobile phones even more indispensable, Nokia and other manufacturers are clearly on the Bluetooth low energy bandwagon. “We see it as part of the continued evolution to the Bluetooth chip set,†says Mika Sarén, Nokia’s Senior Technology Manager for Connectivity. When the specification is released, it will be supported in time for the first product release on Forum Nokia, the company’s web site for developers.

Shipments of Bluetooth, NFC, UWB, 802.15.4 and Wi-Fi ICs Will Increase 20% in 2010
The market for short range wireless ICs is forecast to expand this year; total shipments of Bluetooth, NFC, UWB, 802.15.4 and Wi-Fi ICs will increase approximately 20% compared to 2009. “Bluetooth ICs still lead the short-range wireless IC market,†says ABI Research industry analyst Celia Bo. “Unit shipments are expected to exceed 58% of the total short-range wireless IC shipments in 2010. Wi-Fi ICs rank second place in this market, making up approximately 35% of the total shipments, with the rest of the shipments accounted for by NFC, UWB and 502.15.4 ICs.â€
Wireless Sensor Network IC Shipments Bounce Back in 2010; 645 Million Forecast for 2015
LONDON – September 1, 2010 Demand for wireless sensor networks is showing significant growth following a period in which adoption was impacted by the economic downturn. In 2009, 802.15.4 chipset shipments were down almost 30% compared with the previous year. But according to the latest ABI research report on the WSN market, a strong uplift […]

Is RFDP8 better than BlueTooth, ZigBee, WLAN and other protocols?
RF Digitals RFDP8 proprietary patent-pending frequency agility protocol operates in the internationally accepted 2.4 GHz band. The RFDP8s leading-edge advanced algorithm is not burdened by a heavy-weight stack as is BlueTooth, ZigBee, WLAN and other protocols, which are well suited for cross-manufacturer interoperability. The RFDP8 protocol is highly robust and effective where there is a […]
