7 / 18 page ACE24LC02/04/08/16 Two-wire Serial EEPROM VER 1.6 7 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 during the ninth clock cycle to acknowledge that it has received each word. The 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 ACE24LC02/04/08/16 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 protocol reset by 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. Bus Timing Figure 2.SCL: Serial Clock, SDA: Serial Data I/O |
