CPU Supervisor with Nonvolatile Memory and  
Programmable I/O  
General Description  
Features  
The DS4510 is a CPU supervisor with integrated 64-  
byte EEPROM memory and four programmable, non-  
volatile (NV) I/O pins. It is configured with an  
industry-standard I2C interface using either fast-mode  
(400kbps) or standard-mode (100kbps) communica-  
tion. The I/O pins can be used as general-purpose I2C-  
to-parallel I/O expander with unlimited read/write  
capability. EEPROM registers allow the power-on value  
of the I/O pins to be adjusted to keep track of the sys-  
tem’s state through power cycles, and the CPU supervi-  
sor’s timer can be adjusted between 125ms and  
1000ms to meet most any application need.
