2 / 13 page AME, Inc. 2 Micropower µµµµµP Watch Dog Timer AME8510 / 8520 / 8530 AME8510 AME8520 AME8530 111 RESET/ RESETB This pin may be either RESET or RESETB. RESETB is active low. In the case of the AME8520 and AME8530 this pin will always be the opposite polarity from pin 3. This pin can be push/pull or open drain. 222GND Ground N/A 3 3 RESET/ RESETB This pin may be either RESETB or RESET. RESET is active high. In the case of the AME8520 and AME8530 this pin will always be the opposite polarity from pin 1. This pin can be either push/pull or open drain. 3N/A 4 MRB 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. If this function is unused then float this pin or tie it to VDD. 4 4 N/A WDI Watch Dog Input. Any transition on this pin will reset the watch dog timer. If this pin remains high or low for longer than the watch dog interval then a reset is asserted. Float or tristate this pin to disable the watch dog feature. 555 VDD Positive power supply. A reset is asserted after this voltage drops below a predetermined level. After VDD rises above that level reset remains asserted until the end of the reset timeout period.
