Unterpremstaetten, Austria — (METERING.COM) — August 24, 2007 – austriamicrosystems, a designer and manufacturer of high performance analog ICs, has introduced the AS8267, a system-on-chip single phase energy meter IC supporting 80-segment LCD displays which ensures complete security of both application program and data and offers highly reliable on-chip Flash memory.

The AS8267 provides security protected on-chip data and program memory with reliable data retention specification over an extreme temperature range. It 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.

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.
