AME, Inc. µ µ µProcessor Supervisory µ µ AME8500 / 8501 General Description Typical Operating Circuit The AME8500 family allows the user to customize the CPU reset function without any external components. The user has a large choice of reset voltage thresholds, * 2 reset time intervals, and output driver configurations, all VCC VCC of which are preset at the factory. Each wafer is trimmed AME8500 Processor to the customer's specifications. RESET RESET / RESET These circuits monitor the power supply voltage of µP Input based systems. When the power supply voltage drops GND GND below the voltage threshold a reset is asserted immedi- 3 ately (within an interval TD1). The reset remains asserted after the supply voltage rises above the voltage threshold f
