Synchronous waveforms and timings
Figures 25 through 28 represent synchronous waveforms, tables 76 through 79 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.
•
With capacity load 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 = 100 MHz at CL = 20 pF
•
For 1.71 V < VDD < 1.8 V: maximum FMC_CLK = 95 MHz at CL = 20 pF
•
For 1.71 V < VDD < 1.8 V: maximum FMC_CLK = 100 MHz at CL = 15 pF
