AME µProcessor Supervisory AME8503 n General Description n Application The AME8503 family allows the user to customize the CPU reset function without any external components. The user has serveral choice of reset voltage thresholds, reset time intervals, and output driver configurations, all of which are preset at the factory. l l l l l l 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 open drain. The state of the reset output is guaranteed to be correct only when supply voltages is greater than 1V. The AME8503 also provide a reset manually by pulling the MRB input to ground.

Reset is active high. RESETB is active low. It is also available with an opendrain. Positive power supply. A reset is asserted after this voltage drops below a predetermined level. After VIN rises above that level the reset output remains asserted until the end of the reset timeout periold. 2 5 4 4 IN 3 2 1 1 GND Ground. Manual RESET. Active low. Pulling this pin low forces a reset. After a low to high transition reset, remains asserted for exactly one reset timeout period. This pin is internally pulled high.
