1 / 2 page  Actual size Real time clock module Block diagram This is a block diagram for RTC-7301SF. Be aware that RTC-7301DG differs according to the following 2 points. 1) The VTEMP output is not connected to an external pin. 2) The FCON input pin is not connected to an external pin, but is fixed at "H" internally. External dimensions/Terminal connection (Unit:mm) Specifications (characteristics) *Refer to application manual for details. ■Absolute Max. rating GND=0 V ■DC characteristics (GND=0 V,VDD=1.6 V to 5.5 V,Ta=-40 C to +85 C) Item Symbol Conditions Min.
