136 / 167 page ![]() Electrical characteristics STM32F405xx, STM32F407xx 136/167 Doc ID 022152 Rev 2 PC Card/CompactFlash controller waveforms and timings Figure 60 through Figure 65 represent synchronous waveforms, and Table 79 and Table 80 provide the corresponding timings. The results shown in this table are obtained with the following FSMC configuration: ● COM.FSMC_SetupTime = 0x04; ● COM.FSMC_WaitSetupTime = 0x07; ● COM.FSMC_HoldSetupTime = 0x04; ● COM.FSMC_HiZSetupTime = 0x00; ● ATT.FSMC_SetupTime = 0x04; ● ATT.FSMC_WaitSetupTime = 0x07; ● ATT.FSMC_HoldSetupTime = 0x04; ● ATT.FSMC_HiZSetupTime = 0x00; ● IO.FSMC_SetupTime = 0x04; ● IO.FSMC_WaitSetupTime = 0x07; ● IO.FSMC_HoldSetupTime = 0x04; ● IO.FSMC_HiZSetupTime = 0x00; ● TCLRSetupTime = 0; ● TARSetupTime = 0. In all timing tables, the THCLK is the HCLK clock period. Figure 60. PC Card/CompactFlash controller waveforms for common memory read access 1. FSMC_NCE4_2 remains high (inactive during 8-bit access.
