AT34C02
0958O–SEEPR–12/04
Memory Organization AT34C02, 2K Serial EEPROM: The 2K is internally organized with 16 pages of 16 bytes
each. Random word addressing requires a 8-bit data word address.
Device Operation
CLOCK and DATA TRANSITIONS: The SDA pin is normally pulled high with an exter-
nal device. Data on the SDA pin may change only during SCL low time periods (see
Figure 5 on page 8). Data changes during SCL high periods will indicate a start or stop
condition as defined below.
START CONDITION: A high-to-low transition of SDA with SCL high is a start condition
which must precede any other command (see Figure 5 on page 8).
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 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 to acknowledge that it has
received each word. This happens during the ninth clock cycle.
STANDBY MODE: The AT34C02 features a low-power standby mode which is enabled:
(a) upon power-up or (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.
