austriamicrosystems Introduces Single Phase Energy Meter IC Supporting 80-Segment LCD Displays
austriamicrosystems introduced the AS8267, a new single phase energy meter IC providing security protected on-chip data and program memory with what is claimed to be the most reliable data retention specification over an extreme temperature range.
The feature packed AS8267 energy metering IC includes what is described as a state of the art precision front-end for accurate measurement of all metering parameters. The embedded logic and microcontroller are said to enable easy and versatile customization to the user’s requirements. All anti-tamper measures are integrated in the AS8267 and any attempts of fraud are monitored. Embedded features like LCD drivers, temperature sensor and real-time clock keep the list of external components to the minimum.
The AS8267 supports up to 80-segment LCD display and incorporates an 8-bit MCU, 32kBytes of on-chip flash memory and 9 programmable multi-purpose inputs/outputs. The AS8267’s two universal asynchronous receiver transmitters (UARTs) allow for external communication. A programmable energy LED pulse output is generated on-chip, enabling fast automatic digital calibration. An on-chip temperature sensor and real-time clock are also provided while an additional serial interface allows connection of an optional external EEPROM.
"Our embedded Flash technology, used in the AS8267, meets the highest requirements related to retention of data for metering application program and data," stated Matjaz Novak, Marketing Director Industry & Medical at austriamicrosystems. "In addition, our memory content security feature allows our customers to fully protect their software investment while providing a highly reliable hardware platform for metering applications."
The AS8267 device adds to a portfolio of austriamicrosystems LCD meter system-on-chip products, which include the AS8268, AS8228 and AS8218. The AS8267 is available in a LQFP-64 pin package and is pin compatible with the currently available AS8268, AS8218 and AS8228 ICs.
