PCA2002
32 kHz watch circuit with programmable output period and pulse width
[1] All coordinates are referenced, in m, to the center of the die (see Figure 10 and Figure 11).
[2] The substrate (rear side of the chip) is connected to V
SS
. Therefore, the die pad must be either floating or
connected to V
SS
.
[3] Pad i.c. is used for factory test; in normal operation it must be left open-circuit, and it has an internal
pull-down resistor connected to V
SS
.
