austriamicrosystems introduces AS8267, a feature-packed system-on-chip single phase energy meter IC supporting 80-segment LCD displays

austriamicrosystems (SWX: AMS), a leading designer and manufacturer of high performance analog ICs for the communications, industrial, medical and automotive markets, introduces the AS8267, a new single phase energy meter IC providing security protected on-chip data and program memory with the most reliable data retention specification over an extreme temperature range.

The feature packed AS8267 energy metering IC includes a state of the art precision front-end for accurate measurement of all metering parameters. The embedded logic and microcontroller 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,¡± says 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 unsurpassed accuracy performance of the AS8267 for all measured parameters, including active energy, MAINS voltage and MAINS current, also makes the AS8267 a leader in its field,¡± adds Dave Simpson, applications manager for metering products at austriamicrosystems. ¡°The precision measurement accuracy is consistently repeatable for all measurements.¡±

The AS8267 device adds to a portfolio of austriamicrosystems LCD meter system-on-chip products, which include 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.
