is the time from a valid stop condition of a write sequence to the end of the internal clear/write cycle.
STANDBY MODE: The AT24C512B features a low power standby mode which is
enabled: a) upon power-up and b) after the receipt of the STOP bit and the completion
of any internal operations.
MEMORY RESET: After an interruption in protocol, power loss or system reset, any two-
wire part can be reset by following these steps:
(a) Clock up to 9 cycles, (b) look for SDA high in each cycle while SCL is high and then
(c) create a start condition as SDA is high.
