... LOGIC SERIAL CLOCK (SCL): The SCL input is used to positive edge clock data into each EEPROM device and negative edge clock data out of each device. SERIAL DATA (SDA): The SDA pin is bidirectional for serial data transfer. This pin is open-drain driven and may be wire-ORed with any number of other open-drain or open collector devices ...

... This parameter is characterized and is not 100% tested. 0976Q–SEEPR–8/05 The AT24C04A uses the A2 and A1 inputs for hardwire addressing, and a total of four 4K devices may be addressed on a single bus system. The A0 pin is a no-connect. WRITE PROTECT (WP): The AT24C02A/04A have a WP pin that provides hardware data protection ...

... Figure 3. Start and Stop Definition 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 Figure 3). ACKNOWLEDGE: All addresses and data words are serially transmitted to and from ...

... The next three bits are the A2, A1 and A0 device address bits for the 2K EEPROM. These three bits must compare to their corresponding hardwired input pins. The 4K EEPROM only uses the A2 and A1 device address bits with the third bit being a memory page address bit. The two device address bits must compare to their corre- sponding hardwired input pins ...

... Instead, after the EEPROM acknowledges receipt of the first data word, the microcontroller can transmit up to seven (2K) or fifteen (4K) more data words. The EEPROM will respond with a “0” after each data word received. The microcontroller must terminate the page write sequence with a stop condition, see Figure 9 ...
Page 10
... SEQUENTIAL READ: Sequential reads are initiated by either a current address read or a random address read. After the microcontroller receives a data word, it responds with an acknowledge. As long as the EEPROM receives an acknowledge, it will continue to increment the data word address and serially clock out sequential data words. When the memory address limit is reached, the data word address will “ ...
