Data on the SDA pin may change only during SCL low time periods (refer to Figure 4). 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 (refer to Figure 5). 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 (refer to Figure 5). 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. Following receipt each word from the EEPROM, the microcontroller should send a zero to EEPROM and continue to output the next data word or send a stop condition to finish the read cycle. STANDBY MODE: The FM24C02C 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. DEVICE RESET: After an interruption in protocol, power loss or system reset, any two-wire part can be reset in following these steps: 1. Clock up to 9 Cycles, 2. Look for SDA high in each cycle while SCL is high and then, 3. Create a start condition as SDA is high.

The eighth bit of the device address is the read/write operation select bit. A read operation is initiated if this bit is high and a write operation is initiated if this bit is low. The device address word consists of a mandatory one, zero, one, zero, zero, zero, zero sequence for the first seven most significant bits as shown. Upon a compare of the device address, the EEPROM will output a zero. Data Sheet FM24C02C 2-wrie Serial EEPROM Ver1.6 10 Write Operations Read Operations BYTE WRITE: A write operation requires an 8-bit data word address following the device address word and acknowledgment. Upon receipt of this address, the EEPROM will again respond with a zero and then clock in the first 8-bit data word. Following receipt of the 8-bit data word, the EEPROM will output a zero and the addressing device, such as a microcontroller, must terminate the write sequence with a stop condition. At this time the EEPROM enters an internally timed write cycle, tWR, to the nonvolatile memory. All inputs are disabled during this write cycle and the EEPROM will not respond until the write is complete (refer to Figure 8). Read operations are initiated the same way as write operations with the exception that the read/write select bit in the device address word is set to one. There are three read operations: current address read, random address read and sequential read. PAGE WRITE: The 2K devices are capable of 8-byte page writes. A page write is initiated the same as a byte write, but the microcontroller does not send a stop condition after the first data word is clocked in. Instead, after the EEPROM acknowledges receipt of the first data word, the microcontroller can transmit up to seven more data words. The EEPROM will respond with a zero after each data word received. The microcontroller must terminate the page write sequence with a stop condition (refer to Figure 9). The data word address lower three bits are internally incremented following the receipt of each data word. The higher data word address bits are not incremented, retaining the memory page row location. When the word address, internally generated, reaches the page boundary, the following byte is placed at the beginning of the same page. If more than eight data words are transmitted to the EEPROM, the data word address will “roll over” and previous data will be overwritten. ACKNOWLEDGE POLLING: Once the internally timed write cycle has started and the EEPROM inputs are disabled, acknowledge polling can be initiated. This involves sending a start condition followed by the device address word. The read/write bit is representative of the operation desired. Only if the internal write cycle has completed will the EEPROM respond with a zero allowing the read or write sequence to continue. CURRENT ADDRESS READ: The internal data word address counter maintains the last address accessed during the last read or write operation, incremented by one. This address stays valid between operations as long as the chip power is maintained. The address “roll over” during read is from the last byte of the last memory page to the first byte of the first page. The address “roll over” during write is from the last byte of the current page to the first byte of the same page. Once the device address with the read/write select bit set to one is clocked in and acknowledged by the EEPROM, the current address data word is serially clocked out. The microcontroller does not respond with an input zero but does generate a following stop condition (refer to Figure 10). RANDOM READ: A random read requires a “dummy” byte write sequence to load in the data word address. Once the device address word and data word address are clocked in and acknowledged by the EEPROM, the microcontroller must generate another start condition. The microcontroller now initiates a current address read by sending a device address with the read/write select bit high. The EEPROM acknowledges the device address and serially clocks out the data word. The microcontroller does not respond with a zero but does generate a following stop condition (refer to Figure 11). 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 “roll over” and the sequential read will continue. The sequential read operation is terminated when the microcontroller does not respond with a zero but does generate a following stop condition (refer to Figure 12) Data Sheet FM24C02C 2-wrie Serial EEPROM Ver1.6 11 Figure 7．Device Address MSB 1 0 1 0 0 0 0 LSB R/W Figure 8．Byte Write Figure 9．Page Write Data Sheet FM24C02C 2-wrie Serial EEPROM Ver1.6 12 Figure 10．Current Address Read Figure 11． Random Read Figure 12． Sequential Read Data Sheet FM24C02C 2-wrie Serial EEPROM Ver1.6 13 Ordering Information FM 24C 02 C -PP -C -H Company Prefix FM = Shanghai Fudan Microelectronics Group Co.,ltd Product Family 24C = 2-Wire Serial EEPROM Product Density 02 = 2K-bit Sub-Product Family C = 1.7V to 5.5V Package Type (1) PD = 8-pin PDIP SO = 8-pin SOP TS = 8-pin TSSOP DN = 8-pin TDFN ST = 5-pin TSOT23 M2F or M2P = 8-pin Module Package M3F or M3P = 6-pin Module Package Product Carrier U = Tube T = Tape and Reel R = Module Reel HSF ID Code (2) Blank or R = RoHS Compliant G = RoHS Compliant, Halogen-free, Antimony-free Note: 1.
