FSMC characteristics

Unless otherwise specified, the parameters given in Table 90 to Table 95 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 34 and Figure 35 represent asynchronous waveforms and Table 90 through Table 93

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.
