Oscillator Used to Generate a Reference
Clock for Various System and Peripheral
Clocks
• Supports Individual Clock Enable/Disable
Control for Subsystems and Peripherals
to Facilitate Reduced Power
Consumption
• Five ADPLLs to Generate System Clocks
(MPU Subsystem, DDR Interface, USB
and Peripherals [MMC/SD, UART, SPI,
I2C, etc.], L3, L4, Ethernet, GFX [SGX530],
LCD Pixel Clock)
– Power
• Two Non-Switchable Power Domains
(Real-Time Clock [RTC], Wake-Up Logic
[WAKE-UP])
• Three Switchable Power Domains (MPU
Subsystem [MPU], SGX530 [GFX],
Peripherals and Infrastructure [PER])
• Implements SmartReflex™ Class 2B for
Core Voltage Scaling Based On Die
Temperature, Process Variation and
Performance (Adaptive Voltage Scaling
[AVS])
• Dynamic Voltage Frequency Scaling
(DVFS)
• Real-Time Clock (RTC)
– Real-Time Date (Day/Month/Year/Day of
Week) and Time (Hours/Minutes/Seconds)
Information
