AME µProcessor Supervisory AME8504 n General Description n Application The AME8504 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 either push-pull. The state of the reset output is guaranteed to be correct only when supply voltage is greater than 1V. Portable Electronics Power Supplies Computer Peripherals Data Acquisition Systems Applicatiions using CPUs Consumer Electronics n Typical Application VIN VIN µP RESET INPUT PUSH BUTTON RESET / RESETB SWITCH MRB GND The AME8504 also provide a reset manually by pulling the MRB input to ground. Space saving SC-70 package GND and micropower quiescent current (<3.0µA) make this family a natural for portable battery powered equipment. n Functional Block Diagram n Features l Internally Fixed Threshold 1.2V to 4.5V in 0.1V Step l High Accuracy ±1.5% MRB VIN R1 l Quick Reset within 20µs P1 I2 RESET/ RESETB Delay l Low Supply Current 3µA l No External Components Required I1 R2 V REF N1 GND l Built-in Recovery Delay Include 0ms, 55ms, 220ms, 450ms l Low Functional Supply Voltage 0.9V l Push-Pull Output l Small SOT-143, SC-70-4, SOT-25 and TSOT25A Package l RoHS Compliant and Halogen Free Rev.

Reset is active high. RESETB is active low. It is also available with a push-pull. 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. The pin is floating or tied to VIN, if it is unused. 4 4 3 3 MRB 5 1 N/A N/A NC Rev. A.01 No connection. Not internally connected.
