142 / 184 page ![]() Electrical characteristics STM32F20xxx 142/184 DocID15818 Rev 15 PC Card/CompactFlash controller waveforms and timings Figure 65 through Figure 70 represent synchronous waveforms, with Table 80 and Table 81 providing the corresponding timings. The results shown in these 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. td(CLKL- NADVL) FSMC_CLK low to FSMC_NADV low - 5 ns td(CLKL- NADVH) FSMC_CLK low to FSMC_NADV high 6 - ns td(CLKL-AV) FSMC_CLK low to FSMC_Ax valid (x=16…25) - 0 ns td(CLKL-AIV) FSMC_CLK low to FSMC_Ax invalid (x=16…25) 8 - ns td(CLKL-NWEL) FSMC_CLK low to FSMC_NWE low - 1 ns td(CLKL-NWEH) FSMC_CLK low to FSMC_NWE high 1 - ns td(CLKL-Data) FSMC_D[15:0] valid data after FSMC_CLK low - 2 ns td(CLKL-NBLH) FSMC_CLK low to FSMC_NBL high 2 - ns 1.
