Stresses exceeding the range specified under “Absolute Maxi. Functional operation of this device at other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability.
Input Capacitance See Note. Output Capacitance See Note. After this period the first clock pulse is generated.

Time in which the bus must be free before a new transmission can start. For relative timing, refer to timing diagrams. The SDA pin is bidirectional for datasueet data transfer. The pin is open-drain driven and may be wired-OR with any number of other open-drain or open collector devices.
Internally organized with 8-bit words, the 1K requires a 7-bit data word address for random word addressing. Internally organized with 8-bit words, the 2K requires an 8-bit data word datashewt for random word addressing. Clock and data transition. Data transfer may be initiated only when the. During data transfer, the data line must remain stable whenever the clock line is high.
This happens during the ninth clock cycle. The device address word consist of a mandatory one, zero sequence for the first four most significant bits refer to the diagram show- ing the Device Address. These three bits must compare to their corresponding hard-wired input pins. A read operation is initi- ated if this bit is high and a write operation is initiated if this bit is low.
If not, the chip will return to a standby state.

A write operation requires an 8-bit data word address following the device address word and acknowledgment. Upon receipt of this ad- dress, the EEPROM will again respond with a zero and then clock in the first 8-bit data dxtasheet. After receiving the 8-bit data word, the EEPROM will output a zero and the address- ing device, such as a microcontroller, must terminate the write sequence with a stop con- datasheef.
A page write is initiated the same as byte write, but the microcontroller does not send a stop condition after the first data word is clocked in. Instead, after the EEPROM ac- knowledges the receipt of the first data word, the microcontroller can transmit up to seven more data words. The microcontroller must terminate the page write sequence datsaheet a stop condition.
The higher data word address bits are not incremented, re- taining the memory page row location refer to Datashert write timing.
Since the device will not acknowledge during a write cycle, 24lc022 can be used to determine when the cycle is complete this feature can be used to maximize bus throughput.
Once the stop condition for a write command has been issued from the master, the device initiates the internally timed write cycle. ACK polling can be initiated immediately. If the device is still busy with the. Search field Part name Part description.
