Synchronous waveforms and timings
Figure 22 through Figure 25 represent synchronous waveforms and Table 65 through
Table 68 provide the corresponding timings. The results shown in these tables are obtained
with the following FMC configuration:
•
BurstAccessMode = FMC_BurstAccessMode_Enable
•
MemoryType = FMC_MemoryType_CRAM
•
WriteBurst = FMC_WriteBurst_Enable
•
CLKDivision = 1
•
DataLatency = 1 for NOR Flash, DataLatency = 0 for PSRAM, CL = 30 pF
In all the timing tables, the Tfmc_ker_ck is the fmc_ker_ck clock period, with the following
FMC_CLK maximum values:
•
For 2.7 V<VDD<3.6 V: maximum FMC_CLK = 137 MHz at CL = 20 pF
•
For 1.8 V<VDD<1.9 V: maximum FMC_CLK = 100 MHz at CL = 20 pF
•
For 1.62 V<VDD<1.8 V: maximumFMC_CLK = 88 MHz at CL = 15 pF
