3.6. VRTC Interface

The RTC (Real Time Clock) can be powered by an external power source through VRTC when the

module is powered down and there is no power supply for the VBAT. The external power source can be a

rechargeable battery (such as a button cell battery) according to application demands. A reference circuit

design is shown .

VRTC

100nF

BAT

Figure 11: RTC Powered by a Rechargeable Button Cell Battery

1. When VBAT is disconnected, the recommended input voltage range for VRTC is 2.1V~3.25V and the

recommended typical value is 3.0V.

2. When powered by VBAT, the RTC error is 100ppm. When powered by VRTC, the RTC error is about

200ppm.

3. If a rechargeable battery is use

d, the ESR of battery should be less than 2KΩ, and it is recommended

to use the MS621FE FL11E of SEIKO.

4. If RTC function is not needed, then it is recommended to connect a 47uF capacitor to the VRTC

interface.
