Dear Expert :

TLF35584xxVS1

The chip has Internal Supply and Clock , 

when we use window watchdog , to feed it by SPI command , if we configure the cycle time like 50 wd cycles =50ms , 

how can the chip check the 50ms ? what Characteristics about 35584 clock ? what's the frequence ? could you give me more information about this ? thanks in advance 

all i found the datasheet and usermannual not included the clock details information. 

Thanks inadvace .

Hello,

2MHz is the main clock used in the FSM and for most of the features. The 100kHz clock is mainly used for the low quiescent in STANDBY state, means e.g. all logic related to ldo stby uses the 100kHz clock. Also 100kHz is used for watchdog and wakeup timer.

Internal clock circuitry and function is the confidential data which needs to be discussed with the design team.

Best Regards,

Albab
