NAND controller waveforms and timings
Figure 26 through Figure 29 represent synchronous waveforms, and Table 75 and Table 76
provide the corresponding timings. The results shown in this table are obtained with the
following FMC configuration:
• COM.FMC_SetupTime = 0x01
• COM.FMC_WaitSetupTime = 0x03
• COM.FMC_HoldSetupTime = 0x02
• COM.FMC_HiZSetupTime = 0x01
• ATT.FMC_SetupTime = 0x01
• ATT.FMC_WaitSetupTime = 0x03
• ATT.FMC_HoldSetupTime = 0x02
• ATT.FMC_HiZSetupTime = 0x01
• Bank = FMC_Bank_NAND
• MemoryDataWidth = FMC_MemoryDataWidth_16b
• ECC = FMC_ECC_Enable
• ECCPageSize = FMC_ECCPageSize_512Bytes
• TCLRSetupTime = 0
• TARSetupTime = 0
• C
L
= 30 pF
In all timing tables, the T
fmc_ker_ck
is the fmc_ker_ck clock period.
