Atmel powers data concentrators

Data concentrators are typically used in AMR (automatic meter reading) and AMI (advanced metering infrastructure) architecture to collect information and data, often from multiple meters, before forwarding the data to a utility company. Understandably, they are heavily used in densely populated areas.

Some AMI architectures might utilize a multi-utility communications unit or communications gateway at each home, instead of a meter, to support the HAN and WAN. These communications products or meters connect to a data concentrator, which manages anywhere from 10-2000 devices, depending on the architecture and communication medium adapted.

Atmel microcontrollers can be used to provide the necessary connectivity and processing power for data concentrators, MUCs and communications gateways.

Indeed, Atmel MCUs offer a number of key features for engineers, such as multiple connectivity options that include Ethernet, multiple UARTs, USB and SDIO. Meanwhile, select AVR microcontrollers support USB and OTG, with full or high speed Atmel solutions offering support for a variety of USB classes, including CDC, HID, MS and DFU. Atmel also offers power line communications (PLC) system-on-a-chip (SoC) solutions with full digital implementation to deliver high performance, high temperature stability and best-in-class sensitivity.

Additional key specs include robust processing power supporting application functionality, CryptoAuthentication for security, RF transceivers to facilitate intelligent connectivity and non-volatile serial memory to enable data logging.

“It is important to note that data concentrators are usually positioned in transform centers, and collect communications from several different homes for transfer to the utility. As such, not all of the above communications examples will be supported on any one unit. Basically, communications depend on the AMI architecture implemented,” an Atmel engineering rep told Bits & Pieces.

“Some AMR/AMI architectures do not use a smart electricity meter as the hub of the home system, but instead utilize multi-utility communications (MUC) and communications gateways. These products can connect to a single HAN, or can look after several in an apartment block. MUCs and communications gateways usually supply a bridge between the HAN and WAN, and will connect to data concentrators.¬†Atmel solutions deliver the robust processing power and solid security that is key for critical communications.”

Devices powered by Atmel’s maXTouch controllers¬†boast a wide array of features to facilitate a superior user experience.

This includes intelligent touch processing algorithms, optimized noise suppression, high responsiveness, pinpoint precision and sensor hub technology – all fusing together input from motion-processing sensors such as accelerometers, gyroscopes and magnetometers.

This allows engineers to design a highly responsive, high-fidelity touch experience in mobile devices – even in the most punishing noise environments.

Key applications include:

  • Smartphones
  • Tablets
  • Windows 8 Notebooks and Ultrabooks
  • Digital still cameras
  • e-Readers
  • GPS systems
  • Portable media players
