Synchronous waveforms and timings
Electrical characteristics
Figure 28 through Figure 31 represent synchronous waveforms and Table 36 through
Table 38 provide the corresponding timings. The results shown in these tables are obtained
with the following FSMC configuration:
●
●
●
●
●
BurstAccessMode = FSMC_BurstAccessMode_Enable;
MemoryType = FSMC_MemoryType_CRAM;
WriteBurst = FSMC_WriteBurst_Enable;
CLKDivision = 1; (0 is not supported, see the STM32F10xxx reference manual)
DataLatency = 1 for NOR Flash; DataLatency = 0 for PSRAM
