AME8503 Datasheet Uprocessor Supervisory

Manufacturer: Analog Microelectronics

Overview: AME AME8503 n General.

General Description

The AME8503 family allows the user to customize the CPU reset function without any external ponents.

The user has serveral choice of reset voltage thresholds, reset time intervals, and output driver configurations, all of which are preset at the factory.

These circuits monitor the power supply voltage of µP based systems.
