Intersil Introduces New Family of Highly Integrated, Low-Power Real Time Clocks for Consumer and Industrial Applications28 April 2006
Intersil Corporation (NASDAQ: ISIL), a worldleader in the design and manufacture of high-performance analog solutions, todayintroduced a new family of real time clocks that integrate 4kbits oferasable programmable read only memory (EEPROM) (2.0 million write cycles)and CPU supervisory functions, in a small footprint package designed forspace-constrained applications.
Intersil's ISL12026/27/28/29 family features low power dissipation (800nA batterysupply current) in battery back-up mode, enabling the use of smallbatteries or super caps for back-up, critical in handheld applications. TheISL12027, ISL12028 and ISL12029 also integrate CPU supervisory functions,providing board space savings by eliminating the need for discrete devicesfor power-on reset and watchdog timer.
"Intersil's new family of real time clocks provides a complete set ofleading features for consumer products and industrial applications,including crystal frequency trimming, which is critical for clock accuracyand allows the use of low-cost crystal," said Rouben Gharagozian, marketingdirector for Intersil's Real TimeClocks product group. "They provide the industry's highest reliabilityand performance in small outline packages appropriate for designs withboard space limitations."
Reliability, Low Power and Integration
The combination of low power, high integration and very small footprintmakes these new RTCs ideal for consumer applications such as DVDR (DVDrecordable) and HDTV devices, point-of-sale (POS) systems and otherconsumer electronics devices. Industrial applications include utilitypower meters, heating, air conditioning, ventilation and other industrialequipment. The devices can also be used in handheld applications such asPDAs, scanners, portable medical equipment and other handheld devices.Other applications include HVAC, power metering, security, fire monitoringand other security-related systems.
Key Features
-- Integrated EEPROM and CPU supervisory functions eliminates discrete devices-- Crystal frequency compensation-- Very low power consumption in battery back-up mode-- ISL12028 provides CMOS output; ISL12029 provides open drain output for IRQb (interrupt request bar)-- Two million write cycles for EEPROM Target Applications
-- Consumer equipment such as PDAs, DVDRs, audio and video-- Industrial equipment including HVAC, POS systems, power meters, communications systems-- Scanners, POS and other handhelds About Intersil's Timing Circuits
Intersil has a broad portfolio of timing control products that offers aselection of industry standardquartz- and RC-based timing/oscillator ICs along with real time clocks. Timing circuits provide clockpulsing and synchronization in digital systems as well as pulse modulationcircuits. Real time clocks provide actual time in a digital format forclock displays and computer systems. This portfolio of devices also featureInterSeal™ battery saver technology, programmable temperature compensationand other integrated functions, such as programmable alarms, power-on resetand watchdog timer, EEPROM (erasable programmable read only memory)/SRAM(static random access memory) for control and storage use (16 to 256kb) anda clock divider to provide a clock to other circuits.
