Product data sheet Rev. 08 — 23 August 2010 21 of 30 NXP Semiconductors PCA2000; PCA2001 32 kHz watch circuit with programmable adaptive motor pulse [1] All coordinates are referenced, in μm, to the center of the die (see Figure 2, Figure 13 and Figure 14). [2] The substrate (rear side of the chip) is connected to VSS. Therefore the die pad must be either floating or connected to VSS. [3] Pad i.c. is used for factory tests; in normal operation it should be left open-circuit, and it has an internal pull-down resistance to VSS. 12. Packing information 12.1 Tray information Table 13.
