Addressing Power Issues in Real Time Clock Applications Application Note 1549 Addressing Power Issues in Real Time Clock Applications Introduction Many applications prefer to have these connections powered separately. Examples include: Intersil Real Time Clock (RTC) products now include many products with a variety of functions. Common RTC device is powered down while the I2C bus and functions include a low power 32,768kHz oscillator and microcontroller are active (not recommended since it also the ability to keep time in SRAM registers after initial will violate RTC data sheet, but RTC devices are OK……
