8.5.1 SMBus Master Mode

The DS125BR800 devices support reading directly from an external EEPROM device by implementing SMBus Master mode. When using the SMBus master mode, the DS125BR800 will read directly from specific location in the external EEPROM. When designing a system for using the external EEPROM, the user needs to follow these specific guidelines. For additional information, refer to SNLA228.

  • Set ENSMB = Float — enable the SMBUS master mode.
  • The external EEPROM device address byte must be 0xA0 and capable of 520 kHz operation at 2.5 V and 3.3 V supply.
  • Set the AD[3:0] inputs for SMBus address byte. When the AD[3:0] = 0000'b, the device address byte is 0xB0.

When tying multiple DS125BR800 devices to the SDA and SCL bus, use these guidelines to configure the devices.

  • Use SMBus AD[3:0] address bits so that each device can loaded it's configuration from the EEPROM. Example below is for 4 device.
    • U1: AD[3:0] = 0000 = 0xB0,
    • U2: AD[3:0] = 0001 = 0xB2,
    • U3: AD[3:0] = 0010 = 0xB4,
    • U4: AD[3:0] = 0011 = 0xB6
  • Use a pull-up resistor on SDA and SCL; value = 2 kΩ
  • Daisy-chain READ_EN (pin 26) and ALL_DONE (pin 27) from one device to the next device in the sequence so that they do not compete for the EEPROM at the same time.
    1. Tie READ_EN of the 1st device in the chain (U1) to GND
    2. Tie ALL_DONE of U1 to READ_EN of U2
    3. Tie ALL_DONE of U2 to READ_EN of U3
    4. Tie ALL_DONE of U3 to READ_EN of U4
    5. Optional: Tie ALL_DONE output of U4 to a LED to show the devices have been loaded successfully

Below is an example of a 2 kbits (256 x 8-bit) EEPROM in hex format for the DS125BR800 device. The first 3 bytes of the EEPROM always contain a header common and necessary to control initialization of all devices connected to the I2C bus. CRC enable flag to enable/disable CRC checking. If CRC checking is disabled, a fixed pattern (8’hA5) is written/read instead of the CRC byte from the CRC location, to simplify the control. There is a MAP bit to flag the presence of an address map that specifies the configuration data start in the EEPROM. If the MAP bit is not present the configuration data start address is derived from the DS125BR800 address and the configuration data size. A bit to indicate an EEPROM size > 256 bytes is necessary to properly address the EEPROM. There are 37 bytes of data size for each DS125BR800 device. For additional information on EEPROM programming, refer to SNLA228.

NOTE

The maximum EEPROM size supported is 8-kbits (1024 x 8 bits).
