Description

This is a special oscillator with supervisor system. Three inputs are used to control the oscillator. SENSE (PIN4) controls the voltage supply of the chip . If supply voltage decreases down to the threshold set by EX_VREF (PIN8), the chip disables the oscillator and sets SMC_INICK to LOW. When the voltage is bigger than threshold set by EX_VREF is detected on the SENSE pin, SMC_RST_N (PIN7) is set to HIGH with 20 ms delay and enable s the oscillator. MBL_PWRGD_MR_N (PIN3) is used for manual reset of SMC_RST_N. Use NMI_GATE (NMI_GATE) to disable the oscillator.
