NOTE 1: Either V

NOTE 2: The supply current drawn by the SP691A/693A/800L/800M from the battery (excluding I

goes to 5µA when (V

NOTE 3: "+" = battery-discharging current, "-" = battery-charging current.

NOTE 4: Although presented as typical values, the number of clock cycles for the reset and watchdog timeout

periods are fixed and do not vary with process or temperature.

NOTE 5: RESET is an open-drain output and sinks current only.

NOTE 6: WDI is internally connected to a voltage divider between V

to 1.6V (typ), disabling the watchdog function.

NOTE 7: The chip-enable resistance is tested with V

SP693A/800M. CE

NOTE 8: The chip-enable propagation delay is measured from the 50% point at CE
