High-Speed Digital Interfacing with QSPI
The MAX186/MAX188 can interface with QSPI at high
throughput rates using the circuit in Figure 19. This
QSPI circuit can be programmed to do a conversion on
each of the eight channels. The result is stored in mem-
ory without taxing the CPU since QSPI incorporates its
own micro-sequencer. Figure 19 depicts the MAX186,
but the same circuit could be used with the MAX188 by
adding an external reference to VREF and connecting
REFADJ to VDD.
Figure 20 details the code that sets up QSPI for
autonomous operation. In external clock mode, the
MAX186/MAX188 perform a single-ended, unipolar con-
version on each of their eight analog input channels.
Figure 21, QSPI Assembly-Code Timing, shows the tim-
ing associated with the assembly code of Figure 20. The
first byte clocked into the MAX186/MAX188 is the control
byte, which triggers the first conversion on CH0. The last
two bytes clocked into the MAX186/MAX188 are all zero
and clock out the results of the CH7 conversion.
