12. APMC: Advanced Power Management Controller
52
AT91M5880A
The AT91M55800A features an Advanced Power Management Controller, which optimizes both
the power consumption of the device and the complete system. The APMC controls the clocking
elements such as the oscillators and the PLL, the core and the peripheral clocks, and has the
capability to control the system power supply.
Main Power is used throughout this document to identify the voltages powering the
AT91M55800A and other components of the system, with the exception of the Battery Backup
voltage, which is applied to the VDDBU. Main Power supplies VDDIO, VDDCORE and, if
required, the analog voltage VDDA. A battery or battery capacitor generally supplies the Battery
Backup Power.
The APMC consists of the following elements:

Note:
• The RTC Oscillator, which provides the Slow Clock at 32768 Hz.
• The Main Oscillator, which provides a clock that depends on the frequency of the crystal
• The Phase Lock Loop.
• The ARM Core Clock Controller, which allows entry to the Idle Mode.
• The Peripheral Clock Controller, which conserves the power consumption of unused
• The Master Clock Output Controller.
• The Shut-down Logic, which controls the Main Power.
