NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020. Pin Number Symbol Brief Description SOIC TSSOP 13 X1 X1. The X1 pin is the input of an inverting amplifier and should be connected to one pin of a 32.768kHz quartz crystal. 24 X2 X2. The X2 pin is the output of an inverting amplifier and should be connected to one pin of a 32.768kHz quartz crystal. 35 IRQ Interrupt Output – IRQ. This is an interrupt signal output. This signal notifies a host proces- sor that an alarm has occurred and requests action. It is an open drain active low output. 46 VSS VSS. 57 SDA Serial Data (SDA). SDA is a bidirectional pin used to transfer data into and out of the device. It has an open drain output and may be wire ORed with other open drain or open collector outputs. 68 SCL Serial Clock (SCL). The SCL input is used to clock all data into and out of the device. 71 VBACK VBACK. This input provides a backup supply voltage to the device. VBACK supplies power to the device in the event the VCC supply fails. This pin can be connected to a battery, a Supercap or tied to ground if not used. 82 VCC VCC. X1205 |
