6.4.4 Device SMBus Address

The DS280DF810’s SMBus target address is strapped at power up using the ADDR[1:0] pins. The pin state is read on power up, after the internal power-on reset signal is de-asserted. The ADDR[1:0] pins are four-level LVCMOS IOs, which provides for 16 unique SMBus addresses. The four levels are achieved by pin strap options as follows:

  • 0: 1kΩ to GND
  • R: 10kΩ to GND
  • F: Float
  • 1: 1kΩ to VDD
