AME8502
n General Description
n Application
The AME8502 family allows the user to customize the
CPU reset function without any external components.
The user has a large choice of reset voltage thresholds,
reset time intervals, and output driver configurations, all
of which are preset at the factory. Each wafer is trimmed
to the customers specicications.
There circuits monitor the power supply voltage of µP
based system. 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 push-pull. The state of the
reset output is guaranteed to be correct for supply voltages greater than 0.9V.
