Electrical characteristics
Synchronous waveforms and timings
Figure 58 through Figure 61 represent synchronous waveforms and Table 80 through
Table 82 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 STM32F40xxx/41xxx reference manual)
•
DataLatency = 1 for NOR Flash; DataLatency = 0 for PSRAM
In all timing tables, the THCLK is the HCLK clock period (with maximum
FSMC_CLK = 60 MHz).
