Sleep Mode

A low power mode called Sleep Mode is

implemented on both FM24V05 and FM24VN05

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 I2C-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 I2C-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 I2C pins. Once

the master sends a Slave Address that the FM24V05

identifies, it will “wakeup” and be ready for normal

operation within tREC (400

µs 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.
