Electrical characteristics

PC Card/CompactFlash controller waveforms and timings

Figure 62 through Figure 67 represent synchronous waveforms together with Table 78 and

Table 79 provides 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.
