General Description:
The AME8570M family allows the user to customize the CPU reset function without
any external components. The user has several choices of reset voltage thresholds,
reset time intervals, and output driver configurations, all of which are preset at the
factory.
These circuits monitor the power supply voltage of µP based systems. When the
power supply voltage drops below the voltage threshold a reset is asserted
immediately (within an interval TD1). The reset remains asserted after the supply
voltage rises above the voltage threshold for a time interval, TD2. The reset output
may be either active high (RESET) or active low (RESETB). The reset output may be
configured as either push/pull or open drain. The state of the reset output is
guaranteed to be correct only when supply voltage is greater than 1V.
The AME8570M also provide a reset manually by pulling the MRB input to ground.
Space saving SC-70 package and micropower quiescent current (<3.0µA) make this
family a natural for portable battery powered equipment.

III. Failures In Time Calculation:
Use HTOL test information mentioned in sectionⅣ, FIT (Failures In Time) can be
calculated as below:
FIT = ( x 2 (ν ,
CL )
× 10 9 ) /( 2 × S × H × AF ) = ( 4 .61 × 10 9 ) /( 2 × 77 × 1000 × 280 .59 )
=106.69 (pieces per 109 hours) @ 40℃ with 90% Confidence Level.
Where AF is acceleration factor setting activation energy to 1.0eV as zero failure.
