CPU Supervisor with Nonvolatile Memory and

Programmable I/O

_____________________________________________________________________

Note 1:

All voltages referenced to ground.

Note 2:

The DS4510 does not obstruct the SDA and SCL lines if VCC is switched off, as long as the voltages applied to these

inputs do not violate their min and max input voltage levels.

Note 3:

ISTBY specified with VCC equal to 5.0V, and control port-logic pins are driven to ground or VCC for the corresponding

inactive state (SDA = SCL = VCC), does not include pullup resistor current.

Note 4:

See Typical Operating Characteristics for the

RST output voltage vs. supply voltage.

Note 5:

This parameter is guaranteed by design.

Note 6:

I2C interface timing shown for is for fast-mode (400kHz) operation. This device is also backward compatible with I2C

standard-mode timing.

Note 7:

CB—total capacitance of one bus line in picofarads.

Note 8:

EEPROM write time applies to all the EEPROM memory and SEEPROM memory when

SEE = 0. The EEPROM write time

begins at the occurrence of a stop condition.
