data transfer, the bus master should reattempt communi-
cation at a later time. The MAX6889/MAX6890/
MAX6891 generate a NACK after the command byte
during a software reboot, while writing to the EEPROM,
or when receiving an illegal memory address.
Slave Address
SA7 through SA4 represent the standard 2-wire inter-
face address (1010) for devices with EEPROM. SA3
and SA2 correspond to the A1 and A0 address inputs
of the MAX6889/MAX6890/MAX6891 (hardwired as
logic-low or logic-high). SA0 is a read/write flag bit (0 =
write, 1 = read).
The A0 and A1 address inputs allow up to four
MAX6889/MAX6890 to connect to one bus, while the
A0 address input allows up to two MAX6891s to con-
nect to one bus. Connect A0 and A1 to GND or to the
2-wire serial-interface power supply (see Figure 7).
