Compact, Integrated Power Failure Elapsed Time Counter IC Introduced by AMI Semiconductor.Business Editors/High-Tech Writers POCATELLO, Idaho--(BUSINESS WIRE)--Oct. 20, 2003 Device reduces components, space and cost of factory automation and process control applications requiring accurate measurement of power failure duration AMI Semiconductor AMI Semiconductor is a company engaged the design and manufacture of customer specific integrated circuit solutions, including solutions for the automotive, medical and industrial markets. Among its products are products that integrate processing of analog and digital signals. (Nasdaq:AMIS A·mis , Kingsley 1922-1995. British writer best known for his novels, including Lucky Jim (1954) and Jake's Thing (1978). ) has announced a compact and highly integrated IC that simplifies the design and reduces the component count, space requirements and cost of circuits needed for the accurate and reliable measurement of power failure durations in industrial applications. Developed specifically for operation in industrial environments, the AMIS-70020 offers autonomous stop/start operation and can measure power failure durations of up to five hours with a one-second resolution. The device is particularly suited to factory automation systems -- for instance in inverters and motor drives -- and process control systems. These applications often require accurate knowledge of the elapsed time e·lapsed time n. The measured duration of an event. Noun 1. elapsed time - the time that elapses while some event is occurring of a power failure for protection of the factory equipment or the materials that are being processed. Using the AMIS-70020 power failure elapsed time counter IC, industrial designers can simplify their overall bill of materials The list of components that make up a system. For example, a bill of materials for a house would include the cement block, lumber, shingles, doors, windows, plumbing, electric, heating and so on. (BOM) by eliminating the need for external components including oscillators, diodes and additional power circuitry. During the counting phase, the device can be powered by an external capacitor or a primary lithium coin cell battery to provide maintenance-free operation that is independent from an external power supply. The low power design of the device ensures a current consumption of less than 1 microamp, meaning that the energy stored in a 10mF buffer capacitor is sufficient to measure elapsed time for power failures with durations of up to five hours. Overall Footprint Less Than One-Quarter Inch The AMIS-70020 is supplied in an SO8 package and integrates all necessary counter functionality along with an internal 1kHz oscillator oscillator Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air , power management circuitry for the recharging of the external capacitor and a two-wire interface. When combined with all necessary external components (filter capacitor Filter capacitors are capacitors used to smooth the ripple voltage present in a pulsating DC voltage output of a power supply rectifier. Rectifiers convert an AC supply into a pulsating DC supply. Most modern electronic devices require a steady DC supply. and buffer capacitor or battery), the overall footprint of the circuit is only approximately 15mm2 (0.23inches2). In addition, the two-wire interface provides a simple connection to the standard I/O pins of an external microcontroller without the need for more complex I2C I2C Inter-Integrated Circuit I2C Intelligent Interface Controller I2C Intelligent Controller , SPI (1) (Stateful Packet Inspection) See stateful inspection.

Also known as "universal serial asynchronous receiver transmitter" (USART), it converts parallel bytes from the CPU into serial bits for transmission, and vice interconnectivity. The AMIS-70020 timer IC starts and stops counting automatically based on a comparison of the voltage input signal with a reference signal. When voltage input falls below the reference, a power cut-off is flagged and the timer starts counting. As soon as the input voltage rises above the reference, counting is stopped and the value of the counter and the internal oscillator signal are provided to the microcontroller. A simple algorithm can then be used to calculate the duration of the power failure. The AMIS-70020 has been developed as part of AMI Semiconductor's ongoing product roadmap for the industrial sector and is based on the company's advanced, mixed-signal semiconductor process technology. This technology combines digital and analog capabilities on a single chip to deliver robust and reliable ICs that are ideally suited to operation in the harsh conditions found in industrial environments. Operating voltage range for the new device is specified as between 4.5V and 5.5V, while operating temperature is from -10(degree)C to 85(degree)C.
