General Description

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

mode (400kbps) or standard-mode (100kbps) commu-

nication. The I/O pins can be used as general-purpose

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.
