2 System Control
2.1 Power Supply
It is very important to provide the adequate power and ground for high-speed digital and sensitive
analog circuit. To achieve good and stable quality, the power and ground pins are sepatated into
several groups.

Note 1: According to different application, the VDD voltage can configure differently. For optimum
CPU perfomance, the VDD should be higher than 1.2V. For reducing the power consumption, the
VDD can supply with 1.0V.
2.2 Power Management Unit
ATJ227X only supports LI-ION battery mode. Power Management Unit consists of DC-DC converters,
linear regulators, LI-ION charger, two low resolution A/D converters and power saving control unit.
