195 / 236 page  DS12288 Rev 5 195/236 STM32G474xB STM32G474xC STM32G474xE Electrical characteristics 200 NAND controller waveforms and timings Figure 48 through Figure 51 represent synchronous waveforms, and Table 106 and Table 107 provide the corresponding timings. The results shown in these tables 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 In all timing tables, the THCLK is the HCLK clock period. Table 105. Synchronous non-multiplexed PSRAM write timings(1)(2)(3) 1. CL = 30 pF. 2. Guaranteed by characterization results. 3. Clock ratio R = (HCLK period /FMC_CLK period).
