Interface and Active Power-Pulse Output 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 A single chip that contains the processor (the CPU), non-volatile memory for the program (ROM or flash), volatile memory for input and output (RAM), a clock and an I/O control unit. and analog semiconductors, today announced 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). 3909 energy-measurement IC and reference design. The highly accurate IC combines low power consumption with an SPI interface and active power-pulse output, making it adaptable to a wide variety of meter designs. Together with the MCP3909 3-Phase Energy Meter Reference Design, the IC enables designers to develop and bring meter designs to market quickly. The MCP3909 IC has two 16-bit delta-sigma Analog-to-Digital Converters (ADCs) onboard that can be accessed through its SPI interface, while simultaneously providing a pulse output with a frequency proportional to the active-power calculation. This simultaneous output of data makes the IC flexible and easy to use, as well as adaptable to a variety of meter requirements. Additionally, with its very low, 0.1% typical measurement error over a 1000:1 dynamic range, the MCP3909 IC easily fits into meter applications requiring high accuracy. Its extremely low supply current of only 4 mA makes it suitable for many single- and three-phase energy meter designs, and helps customers remain within their power budget. "With its high levels of integration and accuracy, the MCP3909 is a user-friendly energy measurement IC that can be easily applied to a variety of single- and three-phase metering applications," said Bryan Liddiard, vice president of marketing with Microchip's Analog and Interface Products Division. "Together with the MCP3909 3-phase Energy Meter Reference Design, users can quickly get started on metering designs using PIC([R]) microcontrollers." Development Support The MCP3909 3-Phase Energy Meter Reference Design (Part # MCP3909RD-3PH1) includes three MCP3909 ICs, plus a PIC18F2520 and a PIC18F4550 microcontroller. The PIC18F2520 performs all power calculations in the reference design, while the PIC18F4550 provides a USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. interface to desktop software. The software package that comes with the reference design enables meter calibration and the ability to read active and apparent power, as well as RMS (1) (Record Management Services) A file management system used in VAXs.
