Clock Generator
Clock Generator Block Diagram
• Based on two Power-on-Reset cells
• Status of the last reset
• Controls the internal resets and the NRST pin output
• Shutdown and Wake-up logic
• Embeds the low-power 32768 Hz Slow Clock Oscillator
• Embeds the Main Oscillator
• Embeds 2 PLLs
– One on VDDBU and one on VDDCORE
– 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 pin (SHDN is push-pull)
– Deassertion programmable on a WKUP pin level change or on alarm
– Provides the permanent Slow Clock SLCK to the system
– Oscillator bypass feature
– Supports 3 to 20 MHz crystals
– Output 80 to 240 MHz clocks
– Integrates an input divider to increase output accuracy
– 1 MHz Minimum input frequency
