Reset Controller
Shut Down Controller
Clock Generator
• Based on two Power-on-Reset cells
• Status of the last reset
• Controls the internal resets and the NRST pin output
• Shut-Down and Wake-Up logic
• Embeds the Low Power, fast start-up 32kHz RC Oscillator
• Embeds the Low Power 32768Hz Slow Clock Oscillator
• Embeds the Main Oscillator
• Embeds PLLA primarily for generating processor and master clocks. For full-speed operation
• Embeds PLLB primarily for generating a 96 MHz clock that is divided down to generate the
on the ARM7TDMI processor, this PLL should be programmed to generate a 160 MHz clock
that must then be divided in half to generate the 80 MHz PCK and related clocks.

– Either general reset (VDDBU rising), wake-up reset (VDDCORE rising), software
– Allows shaping a reset signal for the external devices
– Software programmable assertion of the SHDN open-drain pin
– De-assertion Programmable on a WKUP pin level change or on alarm
– Provides the default Slow Clock SLCK to the system
– The SLCK is required for AT91CAP7E to start-up because it is the default clock for
– Requires an external 32768Hz crystal
– Optional Slow Clock SLCK source when a real-time timebase is required
– Requires an external crystal. For systems using the USB features, 12MHz is
– Oscillator bypass feature
– Supports 8 to 16MHz crystals. Recommend 12 MHz crystal if using the USB
– Generates input reference clock for the two PLLs.
– PLLA outputs an 80 to 240MHz clock
– Requires an external RC filter network
– PLLA has a 1MHz minimum input frequency
– Integrates an input divider to increase output accuracy
– PLLB uses an internal low-pass filter (LPF) and can output a 50 to 100 MHz clock
– PLLB and its internal low-pass filter (LPF) are tuned especially for generating a 96
