2.1

Power Supply

With a single external power supply (*1) supplied to V
through V , the S1C6S3N2 Series generates the necessary
SS
internal voltage with the regulated voltage circuit (<V
oscillators, <V
(<V , V > for LCDs). Or the S1C6S3N2 Series generates the
L2 L3
necessary internal voltage with the regulated voltage circuit
(<V > for oscillators, <V

booster circuit (<V
Figures 2.1.1(a) and 2.1.1(b) show the configuration of
power supply.
*1 Supply voltage: 6S3N2 .. 1.8 (2.2)–3.6 V
Note - External loads cannot be driven by the regulated voltage and
voltage booster circuit's output voltage.
- See "7 ELECTRICAL CHARACTERISTICS" for voltage values.
