External capacitor for
power supply regulation
0.47 µF
(one,
or two
in parallel)
The VCC power supply should not be connected to the
VCL pin of the product with the internal step-down
function. (Connect the VCC power supply to other
VCC1 pins as usual.)
Be sure to connect power supply regulating capacitor(s)
to the VCL pin. One or two (parallel) 0.47-µF
multilayer capacitors should be used near the VCL pin.
For 3-V products used with the voltage of 3.6 V or less,
connect the Vcc power supply in the same way as the
products without the internal step-down function.

The VCC2 pin of the product without the internal step-down
function is allocated at the same location as the VCL pin of
the product with the internal step-down function.
It is recommended that a bypass capacitor be connected to
the power supply pins. (The values are reference values.)
