one or two
connected
in group
For products incorporating an internal step-down
circuit, do not connect the VCL pin to the VCC
power supply. (The VCC1 pin must be connected
to the VCC power supply as usual.)
The power supply stabilization capacitor must be
connected to the VCL pin. Use a monolithic
ceramic capacitor of 0.47 µF(one or two
connected in group) and locate it near the pins.
In case the power supply voltage is lower than
3.6 V, connect the capacitor in the same way as
the case with no step-down circuit incorporated.

The location of the VCC2 (V
pin in the product not incorporating an internal
step-down circuit, is the same as the VCL pin in
a product incorporating an internal step-down
circuit.
It is recommended that the by-pass capacitors
are connected to the power supply terminal
(these are reference values).
