4.17 RTC Battery

The CPCI-6200 provides onboard battery clips for holding a coin cell type battery. The clips
allow for the quick and easy replacement of a 3 V button cell lithium battery (CR2430), which
provides back-up power to the onboard M41T83 real-time clock (RTC). A battery switching
circuit that is built into the RTC provides automatic switching between the 3.3 V and battery
voltages. The battery is capable of providing backup power to the RTC for up to 12 years at
nominal temperature.
