Document Outline

A read operation is initi- ated if this bit is high and a write operation is initiated if this bit is low. A write operation requires an 8-bit data word address following the device address word and acknowledgment.

Data Input Hold Time. Internally organized with 8-bit words, the 2K requires an 8-bit data word address for random datasbeet addressing.

Hardware controlled write protection. Input Capacitance See Note. Instead, after the EEPROM ac- knowledges the receipt of the first data word, the microcontroller can transmit up to seven more data words.

After this period the first clock pulse is generated.

The higher data word address bits are not incremented, re- taining the memory page row location refer to Page write timing. 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.


After receiving the 8-bit data word, the EEPROM will output a zero and the address- ing device, datssheet as a microcontroller, must terminate the write sequence with a stop con- dition.

The SDA pin is bidirectional for serial data transfer. 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. Vatasheet receipt of this ad- dress, the EEPROM will again respond with a zero and then clock in the first 8-bit data word. Commerical temperature range 0.

Serial clock data input. Partial page write allowed.

Search field Part name Part description. ACK polling can be initiated immediately. 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.

These three bits must compare to their corresponding hard-wired input pins. Output Valid from Clock. Data transfer may be initiated only when the. Time in which the bus must be free before a new transmission can start. Output Capacitance See Note.


If the device is still busy with the. Since the device will not acknowledge during a write cycle, this can be used to determine when the cycle is complete this feature can be used to maximize bus throughput. The pin is open-drain driven and may be wired-OR with any number of other open-drain or open collector devices. During data transfer, the data line must remain stable whenever the clock line is high. Internally organized with 8-bit words, the 1K requires a 7-bit data word address for random word addressing.

Once the stop condition for a write command has been issued from the master, the device initiates the internally timed write cycle. Data Input Setup Time. This happens during the ninth clock cycle. Characteristics Functional Description Timing Diagrams.

The microcontroller must terminate the page write sequence with a stop condition. Clock and data transition. Write operation with built-in timer.
