其它名称: AT24C1024BN-SH-TCT
STOP CONDITION: A low-to-high transition of SDA with SCL high is a stop condition. After a
read sequence, the Stop command will place the EEPROM in a standby power mode (see Fig-
ure 4-5 on page 8 ).
ACKNOWLEDGE: All addresses and data words are serially transmitted to and from the
EEPROM in 8-bit words. The EEPROM sends a zero during the ninth clock cycle to acknowl-
edge that it has received each word.
STANDBY MODE: The AT24C1024B 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.
SOFTWARE RESET: After an interruption in protocol, power loss or system reset, any 2-wire
part can be protocol reset by following these steps: (a) Create a start bit condition, (b) clock 9
cycles, (c) create another start bit followed by stop bit condition as shown below. The device is
ready for next communication after above steps have been completed.
