Figure 3. Serial-Interface Timing Details
clock starts after a 5s delay, and data transfer begins.
Data transfer disables access to the configuration regis-
ters and EEPROM. The data transfer from EEPROM to
configuration registers takes 3ms (max). Read configu-
ration EEPROM data at any time after power-up or soft-
ware reboot. Write commands to the configuration
EEPROM are allowed at any time after power-up or soft-
ware reboot, unless the configuration lock bit is set (see
Table 22). The maximum cycle time to write a single
byte is 11ms (max).
User EEPROM
The 512-bit, user-EEPROM addresses range from 40h to
7Fh (see Figure 2). Store software revision data, board
revision data, and other data in these registers. The max-
imum cycle time to write a single byte is 11ms (max).
Configuration Register Bank and EEPROM
The configuration registers can be directly modified
through the serial interface without modifying the
EEPROM, after the power-up procedure terminates and
the configuration EEPROM data has been loaded into the
configuration register bank. Use the write byte or block
write protocols to write directly to the configuration regis-
ters. Changes to the configuration registers take effect
immediately and are lost upon power removal.
At device power-up, the register bank loads configura-
tion data from the EEPROM. Configuration data may be
directly altered in the register bank during application
development, allowing maximum flexibility. Transfer the
new configuration data byte-by-byte to the configura-
tion EEPROM with the write byte protocol. The next
device power-up or software reboot automatically loads
the new configuration.
SMBus/I2C-Compatible Serial Interface
The MAX6889/MAX6890/MAX6891 feature an I2C/SMBus-
compatible 2-wire serial interface consisting of a serial
data line (SDA) and a serial clock line (SCL). SDA and
SCL facilitate bidirectional communication between the
MAX6889/MAX6890/MAX6891 and the master device at
clock rates up to 400kHz. Figure 3 shows the 2-wire inter-
face timing diagram. The MAX6889/MAX6890/MAX6891
are transmit/receive slave-only devices, relying upon a
