66 / 123 page ![]() Electrical characteristics STM32F103xC, STM32F103xD, STM32F103xE 66/123 Doc ID 14611 Rev 7 Synchronous waveforms and timings 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 Figure 28.
