Figure 17. MAX1245 QSPI Connections
The MAX1245 can interface with QSPI using the circuit in
Figure 17 (f
QSPI circuit can be programmed to do a conversion on
each of the eight channels. The result is stored in memory
without taxing the CPU, since QSPI incorporates its own
micro-sequencer.
Because the maximum external clock frequency is
1.5MHz, the MAX1245 is QSPI compatible up to 1.5MHz.
