EM Microelectronic's New 32768Hz Crystal Oscillator Boasts High Accuracy With Three Times Better Thermal Drift.Business Editors COLORADO SPRINGS Colorado Springs, city (1990 pop. 281,140), seat of El Paso co., central Colo., on Monument and Fountain creeks, at the foot of Pikes Peak; inc. 1886. It is a year-round resort and a booming military, technological, and commercial city. , Colo.--(BUSINESS WIRE)--Dec. 10, 2002 New EM7602 Combines Excellent Stability With Very Low Power Consumption In 4-Pin SMD (1) (Storage Module Device) A high-performance hard disk interface used with minis and mainframes that transfers data in the 1-4 MBytes/sec range (SMD-E provides highest rate). See hard disk. Package EM Microelectronic has released the EM7602, a low-power 32.768kHz clock 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 with three times better thermal drift than any conventional tuning fork crystal available. The EM7602 features patented frequency factory trimming by EEPROM (Electrically Erasable Programmable ROM) A rewritable memory chip that holds its content without power. Although EEPROMs spawned flash memory, EEPROMs are byte addressable at the write level, whereas flash chips must erase a block of bytes before rewriting. via the serial interface, allowing EM to provide better calibration tolerances. The EM7602 consists of a patented torsional tor·sion n. 1. a. The act of twisting or turning. b. The condition of being twisted or turned. 2. tuning fork crystal and a low-power integrated circuit integrated circuit (IC), electronic circuit built on a semiconductor substrate, usually one of single-crystal silicon. The circuit, often called a chip, is packaged in a hermetically sealed case or a nonhermetic plastic capsule, with leads extending from it for assembled in the same four-pin SMD package. The device combines excellent oscillator stability and very low power consumption. The EM7602 has a low voltage Low voltage is an electrical engineering term that broadly identifies safety considerations of an electricity supply system based on the voltage used. While different definitions exist for the exact voltage range covered by "low voltage", the most commonly used ones include "mains operation of 1.8V to 3.6V. Its temperature range is standard at -40 degrees C to +85 degrees C. The new device can replace standard quartz as a solution to the limitations of miniaturization min·i·a·tur·ize tr.v. min·i·a·tur·ized, min·i·a·tur·iz·ing, min·i·a·tur·iz·es To plan or make on a greatly reduced scale. min or when application difficulties arise with quartz. "EM Microelectronic's solution beats all others in temperature compensation and miniaturization when compared to our competition," said Mougahed Darwish, president of the management board of EM Microelectronic. "The EM7602 rises above all the rest in both performance and price." The EM7602 is used as a general purpose clock generator A clock generator is a circuit that produces a timing signal (known as a clock signal and behaves as such) for use in synchronizing a circuit's operation. It can range from a simple symmetrical square wave to more complex arrangements. in digital systems. It is especially well suited for electricity metering and automotive (dashboard) applications. It is also sold to component manufacturers in a chip set as an input clock driver for EM's Real Time Clocks, to be used instead of quartz when better thermal stability is needed; and for all EM microcontrollers that can be driven using an external clock. It is also sold as an add-on circuit to other microcontroller manufacturers. The EM7602 is unique in combining the following features: -- Low power with 6uA typical at 3V -- Thermo-compensation with a temperature drift of only -0.012 ppm/C2 -- Quartz and IC assembled in the same very small SMD package -- High driver capability of the 32768 Hz output (can replace several quartzes) -- High accuracy (frequency factory trimmed by 8bits EEPROM) -- Tri-state output Pricing and Availability The EM7602 is available now from EM and its authorized distributors as an integrated circuit plus quartz in an SMD package. The EM7602 pricing starts at $3.36 each in quantities of 10,000 units. More information about the new EM7602 crystal oscillator is available at www.emmicroelectronic.com.
