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) communication. 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 system’s state through power cycles, and the CPU supervisor’s timer can be adjusted between 125ms and 1000ms to meet most any application need.

The maximum SCL clock frequency is 400 kHz for fast-mode operation.
Yes, configuring the SEEPROM as SRAM allows infinite write cycles and eliminates EEPROM write time.
Yes, the RST pin is an open-drain output, so an external pullup resistor must be used.
