POWER SUPPLY AND INITIAL RESET

2.1 Power Supply

With a single external power supply (*1) supplied to V
through V , the E0C6001 Series generate the necessary
SS
internal voltages with the regulated voltage circuit (<V
oscillators and internal circuit) and the voltage booster/
reducer (<V

is selected, the E0C6001 short-circuits between <V
<V >, and the voltage reducer generates <V

The E0C60L01 short-circuits between <V
the voltage booster generates <V
The voltage <V
by the regulated voltage circuit is -1.2 V (V
Figure 2.1.1 shows the power supply configuration of the
E0C6001 Series in each condition.
