If additional device addresses are required, a resistor can be
connected to the SA0 pin according to Table 22 to provide up to
25 unique device addresses. In this case, the SA1 pin should be
tied to SGND.

Using this method, the user can theoretically configure up to 625
unique SMBus addresses, however the SMBus is inherently
limited to 128 devices so attempting to configure an address
higher than 128 (0x80) will cause the device address to repeat
(i.e., attempting to configure a device address of 129 (0x81)
would result in a device address of 1). Therefore, the user should
use index values 0 to 4 on the SA1 pin and the full range of index
values on the SA0 pin, which will provide 125 device address
combinations.
To determine the SA0 and SA1 resistor values given an SMBus
address (in decimal), follow the indicated steps to calculate an
index value and then use Table 23 to select the resistor that
corresponds to the calculated index value as follows:
1. Calculate SA1 Index:
28.7
0x0B
100
0x18
SA1 index = Address (in decimal) ÷ 25
(EQ. 34)
31.6
0x0C
2. Round the result down to the nearest whole number.
(EQ. 33)
If more than 25 unique device addresses are required or if other
SMBus address values are desired, both the SA0 and SA1 pins
can be configured with a resistor to SGND according to Equation
SMBus address = 25 x (SA1 index) + (SA0 index)
(in decimal)
Note that the SMBus address 0x4B is reserved for device test and
cannot be used in the system.
3. Select the value of R1 from Table 23 using the SA1 Index
rounded value from Step 2.
4. Calculate SA0 Index:
SA0 index = Address - (25 x SAl Index) (EQ. 35)
5. Select the value of R0 from Table 23 using the SA0 Index
value from step 4.
Digital-DC Bus
The Digital-DC Communications (DDC) bus is used to
communicate between Zilker Labs Digital-DC devices. This
dedicated bus provides the communication channel between
devices for features such as sequencing, fault spreading, and
current sharing. The DDC pin on all Digital-DC devices in an
application should be connected together. A pull-up resistor is
required on the DDC bus in order to guarantee the rise time as
follows:
26
Risetime = R PU ? C LOAD ≈ 1 μ s
