FF24 MODE Input

5-level input strap pin. Sets device control configuration modes. The pin can be exercised at device power up or in normal operation mode. Note the pull-down resistor values as outlined below are different than other 5-level pins of the device.

L1: SMBus/I2C controller mode - device control configuration is read from external EEPROM. When the device has finished reading from the EEPROM successfully, it will drive the ALL_DONE_N pin LOW. SMBus/I2C target operation is available in this mode before, during or after EEPROM reading. Note during EEPROM reading if the external SMBus/I2C controller wants to access the device registers it must support arbitration. To set the pin for L1 pull-down with 2.062 kΩ±10% resistor.

L2: SMBus/I2C target mode – device control configuration is done by an external controller with SMBus/I2C controller. To set the pin for L2 pull-down with 6.225 kΩ±10% resistor.

L0, L3 and L4: RESERVED – TI internal test modes.
FF27 ALL_DONE# Output

EEPROM loading is done. Active low 3.3 V open drain output pin. The pin can be left unconnected.

In SMBus/I2C controller mode: Indicates the completion of a valid EEPROM register load operation. External pullup resistor such as 4.7 kΩ required for operation.

  • High: External EEPROM load failed or incomplete
  • Low: External EEPROM load successful and complete

In SMBus/I2C target: The pin is High-Z.
FF30 B_ADDR1_15-8 Input 5-level input strap pins, as provided in Table 7-3. Sets SMBus/I2C target address, as provided in Table 8-1 and Table 8-2.

 Input

FJ25 READ_EN_# Input

Initiate EEPROM load. Active low 3.3 V LVCMOS input..

In SMBus/I2C controller mode: After device power up, when the pin is low, it initiates the EEPROM read function. Once EEPROM read is complete (indicated by ALL_DONE# asserted low), this pin can be held low for normal device operation. During the EEPROM load process the device’s signal path is disabled.

In SMBus/I2C target: In these modes the pin is not used. The pin can be left floating. The pin has internal 1-MΩ weak pull-down resistor.
