AME, Inc. AME8570 Processor Supervisory General Description Functional Block Diagram AME8570 Push-Pull RESET/ RESETB The AME8570 family allows the user to customize the CPU reset function without any external components. The user has serveral choice of reset voltage thresholds, IN reset time intervals, and output driver configurations, all R1 P1 I1 of which are preset at the factory. RESET/ These circuits monitor the power supply voltage of µP Delay RESETB based systems. When the power supply voltage drops R2 VREF below the voltage threshold a reset is asserted immedi- N1 ately ( within an interval TD1 ). The reset remains asserted GND after the supply voltage rises above the voltage threshold for a time interval, TD2. The reset output may be either AME8570 Ope
