NAND controller waveforms and timings

Figure 84 through Figure 87 represent synchronous waveforms, and Table 175 and

Table 176 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

•

Capacitive load CL = 30 pF

In all timing tables, the Tfmc_ker_ck is the fmc_ker_ck clock period.
