Microchip Technology Provides a Complete Energy Meter Solution With New Energy Measurement ICs.CHANDLER, Ariz. -- Microchip Technology  Microchip Technology (NASDAQ: MCHP) is a manufacturer of microcontroller, memory and analog semiconductors, founded in 1989 when Inc. (NASDAQ NASDAQin full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on : MCHP MCHP Maryland Children's Health Program MCHP Microchip Technologies (stock symbol) MCHP Micro-sized Combined Heat and Power (American Honda Motor Co. & Climate Energy, LLC) MCHP Maine Community Heritage Project ), a leading provider of microcontroller and analog semiconductors, today introduced the MCP (1) See Microsoft certification. (2) (MultiChip Package) A chip package that contains two or more chips. It is essentially a multichip module (MCM) that uses a laminated, printed-circuit-board-like substrate (MCM-L) rather than ceramic (MCM-C). 3905 and MCP3906 -- fully functional, stand-alone energy-measurement integrated circuits Integrated circuits Miniature electronic circuits produced within and upon a single semiconductor crystal, usually silicon. Integrated circuits range in complexity from simple logic circuits and amplifiers, about 1/20 in. (1. (ICs) that output average and instantaneous real power. When these analog front ends are paired with a PIC(R) microcontroller, engineers have a complete, highly accurate solution for single-phase energy measurement in residential power meters and industrial applications. The MCP3905 and MCP3906 each integrate two 16-bit delta-sigma analog-to-digital converters (ADCs), an internal voltage reference A voltage reference is an electronic device (circuit or component) that produces a fixed (constant) voltage irrespective of the loading on the device, power supply variation and temperature. , plus all of the digital circuitry needed to calculate average and instantaneous real power from voltage and current channels. The MCP3905 features a programmable gain amplifier (PGA (1) (Professional Graphics Adapter) An early IBM PC display standard for 3D processing with 640x480x256 resolution. It was not widely used. (2) (Programmable Gate Array) See gate array and FPGA. ) with a maximum gain of 16. For energy meters requiring higher accuracy, the MCP3906 has a maximum gain of 32. These solutions meet or exceed the requirements of the International Electrotechnical Commission See IEC. (standard, body) International Electrotechnical Commission - (IEC) A standardisation body at the same level as ISO. IEC (International Electrotechnical Commission, Geneva, Switzerland, www.iec.ch) An organization that sets international electrical and electronics standards founded in 1906. It is made up of national committees from over 60 countries. IEC - International Electrotechnical Commission 62053 international energy-metering specifications. The new energy-measurement ICs provide high accuracy, with a 0.1 percent typical measurement error over a 500:1 dynamic range for the MCP3905, and 1000:1 dynamic range for the MCP3906. A low-drift, on-chip voltage reference ensures that measurements do not change during the life of the energy meter. In addition, the devices offer low current consumption of 4 milliamps, direct drive for both mechanical counters and two-phase stepper motors, a tamper output pin for negative power indication, and an industrial temperature range of -40 degrees Celsius to 85 degrees Celsius. "The MCP390X energy-measurement ICs address the growing market for electronic-based energy meters, particularly in worldwide emerging markets," said Trent Butcher, product-marketing engineer for Microchip's Analog and Interface Product Division. "Microchip provides additional features for existing PIC microcontroller PIC is a family of Harvard architecture microcontrollers made by Microchip Technology, derived from the PIC1650 originally developed by General Instrument's Microelectronics Division. The name PIC was originally an acronym for "Programmable Intelligent Computer". metering designs and a highly attractive system solution for new metering customers with these new ICs." Microchip offers the MCP3905/MCP3906 Energy Meter Reference Design Board (Part # MCP3905RD-PM1) and the MCP3905/MCP3906 Energy Meter Evaluation Board (Part # MCP3905EV) in support of energy-meter application development. The MCP3905RD-PM1 is priced at $45, and the MCP3905EV at $75. Both boards are available today.
