Multiple Devices with Separate Chip
Selects
devices by using separate chip selects as shown in
Figure 6. The advantage of this method over daisy
chaining is that any of the N 5173 devices may be
updated with a single 16-bit SPI operation (as
opposed to the long Nx16 bit data stream required
when N devices are daisy chained). The disadvantage
of this method is N different chip selects must be
supplied to the individual devices.

microcontroller, with independent chip selects.

Daisy Chaining
ing the DOUT of device n to the DIN pin of device
n+1, as shown in Figure 7. Data is loaded by hold-
ing the common CS low for 16 x N SCLK pulses,
where N = total number of devices in the daisychain.
All devices are simultaneously updated on the rising
edge of CS, particularly useful in applications where
updates to a large number of channels must be syn-
chronized. Another advantage of this method is one
chip select can be shared by all devices, simplifying
the digital control circuitry on the PCB. The disad-
vantage is all N devices must be updated as a group,
thereby slowing down the rate of control to each indi-
vidual device.
