COMMENT
Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
This is a stress rating only; the functional operation of the
device (at these or any other conditions above those
listed in the operational sections of this specification) is
not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect device reliability.
D.C. OPERATING CHARACTERISTICS
(Over the recommended operating conditions unless otherwise specified.)
Notes: (1) The device enters the active state after any start, and remains active until: 9 clock cycles later if the device select bits in the slave
address byte are incorrect; 200ns after a stop ending a read operation; or t
WC
after a stop ending a write operation.
(2) The device goes into standby: 200ns after any stop, except those that initiate a nonvolatile write cycle; t
WC
after a stop that initiates a
nonvolatile cycle; or 9 clock cycles after any start that is not followed by the correct device select bits in the slave address byte.
