Reset Controller
Shutdown Controller
Clock Generator
• 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 a Low-power 32,768 Hz Slow Clock Oscillator and a Low-power RC oscillator
• Embeds the Main Oscillator
• Embeds 2 PLLs
selectable with OSCSEL signal
– 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
– 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
– PLLA outputs 80 to 240 MHz clock
– PLLB outputs 70 to 130 MHz clock
– Both integrate an input divider to increase output accuracy
– PLLB embeds its own filter
reset, user reset or watchdog reset
