Intersil Corporation has introduced what’s said to be the world’s first full-featured, AC-driven Real Time Clock (RTC) devices. The new ICs will be designed into a wide range of industrial and consumer products, from power meters and security devices to white goods and other high-end appliances that require precise measurement of time. With integrated functionality such as dual alarms, event detection and a “brownout” alert, the ISL12030 and ISL12032 have the broadest feature set of any RTCs on the market.
Other features include an automatic crystal oscillator backup in case the AC line frequency is lost (ISL12032); an integrated trickle charger that allows a rechargeable energy source such as a super capacitor or rechargeable battery to be used as a backup supply; dual alarms for reporting problems with system performance; a power status “brownout” alarm that allows the system to save vital information to memory before a complete power loss occurs; time stamp, which records the time and date of events including power loss, recovery, and tampering, a feature particularly important in metering devices; and a battery status monitor that provides warning if battery voltage drops below a certain threshold.
