ELECTRICAL CHARACTERISTICS (Conditions are as follows, unless otherwise specified)
All typical values are for 25°C ambient temperature and 5 V at pin Vcc. Maximum and minimum specifications are over
the recommended operating conditions. All voltages are referred to the voltage at pin Vss. Bit 7 in control register 0 is
“1”, while other bits in control registers are “0”. 400kHz TTL input at SCL. SDA pulled to Vcc through an external 2kΩ
resistor. 2-wire interface in “standby” (see notes 1 and 2 below). WP, A0, A1, and A2 floating.

Notes: 1. The device goes into Standby: 200 ns after any STOP, except those that initiate a nonvolatile write cycle. It goes into Standby t_WC after
a STOP that initiates a nonvolatile write cycle. It also goes into Standby 9 clock cycles after any START that is not followed by the cor-
rect Slave Address Byte.
2. t_WC is the time from a valid STOP condition at the end of a write sequence to the end of the self-timed internal nonvolatile write cycle. It
is the minimum cycle time to be allowed for any nonvolatile write by the user, unless Acknowledge Polling is used.
3. This parameter is periodically sampled and not 100% tested.
