Synchronous waveforms and timings

Figure 24 through Figure 27 represent synchronous waveforms and Table 72 through

Table 75 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

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, FMC_CLK =100 MHz at 20 pF



For 1.8 V<VDD<1.9 V, FMC_CLK =100 MHz at 20 pF



For 1.62 V<VDD<1.8 V, FMC_CLK =100 MHz at 15 pF

1. Guaranteed by characterization results.
