191 / 232 page ![]() DocID025976 Rev 4 191/232 STM32L476xx Electrical characteristics 207 6.3.28 FSMC characteristics Unless otherwise specified, the parameters given in Table 90 to Table 103 for the FMC interface are derived from tests performed under the ambient temperature, fHCLK frequency and VDD supply voltage conditions summarized in Table 22, with the following configuration: • Output speed is set to OSPEEDRy[1:0] = 11 • Capacitive load C = 30 pF • Measurement points are done at CMOS levels: 0.5VDD Refer to Section 6.3.14: I/O port characteristics for more details on the input/output characteristics. Asynchronous waveforms and timings Figure 37 through Figure 40 represent asynchronous waveforms and Table 90 through Table 97 provide the corresponding timings. The results shown in these tables are obtained with the following FMC configuration: • AddressSetupTime = 0x1 • AddressHoldTime = 0x1 • DataSetupTime = 0x1 (except for asynchronous NWAIT mode, DataSetupTime = 0x5) • BusTurnAroundDuration = 0x0 In all timing tables, the THCLK is the HCLK clock period. |
