DESCRIPTION  
The DS1236 MicroManager Chip provides all the necessary functions for power supply monitoring, reset  
control, and memory backup in microprocessor-based systems. A precise internal voltage reference and  
comparator circuit monitor power supply status. When an out-of-tolerance condition occurs, the  
microprocessor reset and power-fail outputs are forced active, and static RAM control unconditionally  
write protects external memory. The DS1236 also provides early warning detection of a user-defined  
threshold by driving a non-maskable interrupt. External reset control is provided by a pushbutton reset
