8 / 17 page FM24V05 - 512Kb I2C FRAM Document Number: 001-84462 Rev. *B Page 8 of 17 Sleep Mode A low power mode called Sleep Mode is implemented on both FM24V05 devices. The device will enter this low power state when the Sleep command 86h is clocked-in. Sleep Mode entry can be entered as follows: 1. The master sends a START command. 2. The master sends Reserved Slave ID 0xF8 3. The master sends the I 2C-bus slave address of the slave device it needs to identify. The last bit is a „Don‟t care‟ value (R/W bit). Only one device must acknowledge this byte (the one that has the I 2C-bus slave address). 4. The master sends a Re-START command. 5. The master sends Reserved Slave ID 0x86 6. The FM24V05 sends an ACK. 7. The master sends STOP to ensure the device enters sleep mode. Once in sleep mode, the device draws IZZ current, but the device continues to monitor the I 2C pins. Once the master sends a Slave Address that the FM24V05 identifies, it will “wakeup” and be ready for normal operation within tREC (400 s max.). As an alternative method of determining when the device is ready, the master can send read or write commands and look for an ACK. While the device is waking up, it will NACK the master until it is ready.
