High-S peed Digital Interfac ing with QS PI
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 V
DD
.
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.
