When writing data to the memory, it responds to the

8 bits received by asserting an acknowledge bit

during the 9th bit time. When data is read by the

bus master, it acknowledges the receipt of the data

bytes in the same way. Data transfers are termi-

nated with a STOP condition.

order to prevent data corruption and inadvertent

write operations during power up, a Power On

voltage has reached the POR threshold value, the

internal reset is active, all operations are disabled

and the device will not respond to any command.

Notes: 1. Except for the rating "Operating Temperature Range", stresses above those listed in the Table "Absolute Maximum Ratings"

may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other

conditions above those indicated in the Operating sections of this specification is not implied. Exposure to Absolute Maximum

Rating conditions for extended periods may affect device reliability. Refer also to the STMicroelectronics SURE Program and other

relevant quality documents.
