23. Power Management Controller (PMC)
23.1
1768I–ATARM–09-Jul-09
Overview
The Power Management Controller (PMC) generates all the clocks of a system thanks to the
integration of two oscillators and two PLLs.
The PMC provides clocks to the embedded processor and enables the idle mode by stopping
the processor clock until the next interrupt.
The PMC independently provides and controls up to thirty peripheral clocks and four program-
mable clocks that can be used as outputs on pins to feed external devices. The integration of the
PLLs supplies the USB devices and host ports with a 48 MHz clock, as required by the bus
speed, and the rest of the system with a clock at another frequency. Thus, the fully-featured
Power Management Controller optimizes power consumption of the whole system and supports
the Normal, Idle, Slow Clock and Standby operating modes.
The main features of the PMC are:
• Optimize the Power Consumption of the Whole System
• Embeds and Controls:
• Provides:
• Four Operating Modes:
– One Main Oscillator and One Slow Clock Oscillator (32.768 kHz)
– Two Phase Locked Loops (PLLs) and Dividers
– Clock Prescalers
– the Processor Clock PCK
– the Master Clock MCK
– the USB Clocks, UHPCK and UDPCK, Respectively for the USB Host Port and the
– Programmable Automatic PLL Switch-off in USB Device Suspend Conditions
– up to Thirty Peripheral Clocks
– up to Four Programmable Clock Outputs
– Normal Mode, Idle Mode, Slow Clock Mode, Standby Mode
