Intersil's New Real Time Clock Features Tamper Detect and InterSeal™ Battery Saver Technology
-- ISL1209 features event-detect function for tamper detection and time stamp~-- Intersil's InterSeal technology prevents initial battery current drain until the unit is powered up
MILPITAS, CA, July 07, 2005 – Intersil Corporation (NASDAQ: ISIL), a world leader in the design and manufacture of high performance analog solutions, introduced today the ISL1209 Real Time Clock (RTC) that combines high-precision, low-power for a wide variety of applications which require very accurate clock and calendar functions with Event Detect. Applications for this device are varied, such as electronic power meters, ATM, medical and other security related equipment and systems. In addition, the device incorporates Intersil’s InterSeal battery saver technology, which prevents any current drain on the battery until the unit is first powered up.
The ISL1209 features an Event Detect and Time Stamp function; this is important for applications requiring increased security, warranty monitoring, data collection and/or event recording. The feature allows for recording event times, such as, when an enclosure or door was opened, etc. This makes the ISL1209 ideal for applications requiring anti-tampering and security such as set-top boxes, utility meters, security alarm and security camera systems or vending machines.
“In addition to providing accurate clock and calendar functions, our new real time clock integrates timing and crystal compensation, flexible alarm, programmable clock output, power fail detection and intelligent battery backup switching into one space saving package,” said Rouben Gharagozian, marketing director for Timing Devices at Intersil. “In addition, its low 400nA current consumption at 3.0V and small package make it an ideal choice for portable, handheld, battery-powered equipment and microprocessor applications where space is at a premium.”
Applications with high accuracy requirements will benefit from using the ISL1209, which contains circuitry for adjusting the frequency of the crystal oscillator through ATR (Analog Trimming Registers) and DTR (Digital Trimming Registers). This circuitry can be used to tune oscillator initial frequency, as well as, adjust to compensate for temperature changes. The oscillator uses an external, 32.768kHz crystal. The RTC tracks time with separate registers for hours, minutes and seconds. The device has calendar registers for date, month, year and day of the week. The calendar is accurate through 2099, with automatic leap year correction.
The IRQ/FOUT provides one of 15 different frequency output ranging from 32.768 kHz down to 1/32Hz for micro controller and other timing circuits. Users have access to 2 bytes of battery-backed SRAM that can be used for scratchpad memory.
The InterSeal feature is an obvious benefit for products that might be stored for some time before they are first used. Applications for these products include telecom systems, consumer electronics, industrial, medical devices, and security related equipment and systems.
