6.3.29 FSMC characteristics
Unless otherwise specified, the parameters given in Table 105 to Table 118 for the FMC 
interface are derived from tests performed under the ambient temperature, f
HCLK
 frequency 
and V
DD
 supply voltage conditions summarized in Table 23, 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: 0.5V
DD
Refer to Section 6.3.14: I/O port characteristics for more details on the input/output 
characteristics.
Asynchronous waveforms and timings
Figure 45 through Figure 48 represent asynchronous waveforms and Table 105 through 
Table 112 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.
