NAND controller waveforms and timings
Figure 34 through Figure 37 represent synchronous waveforms, and Table 87 and Table 88
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.
