Real-time clock equipped with battery saver technology

The ISL1208 is designed with Intersil Corp.’s proprietary battery saver technology called InterSeal, which prevents initial battery current drain on products until the unit is first powered up. The ISL1208 is the first chip in Intersil’s portfolio to implement the technology. It is also designed with analog trimming registers (ATR) and digital trimming registers (DTR), which dramatically improve the real-time clock’s accuracy. Manufactured on a 0.6-micron, CMOS process, the clocking device also offers ultra-low power consumption at 400nA (nanoamp) in battery back-up mode.
