Single-phase energy meter IC supports 80-segment LCD displays

Unterpremstaetten, Austria—austriamicrosystems has introduced the AS8267, a single phase energy meter IC providing security protected on-chip data and program memory with reliable data-retention specifications over an extreme temperature range.

The AS8267 energy metering IC includes a precision front-end for accurate measurement of all metering parameters. The AS8267 embeds logic, a microcontroller, LCD drivers, temperature sensor and real-time clock. All anti-tamper measures are integrated in the AS8267 and any attempts of fraud are monitored.

The AS8267 supports up to 80-segment LCD displays 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.

The AS8267 is available in an LQFP-64 pin package.
