FMC characteristics

Unless otherwise specified, the parameters given in Table 66 to Table 79 for the FMC

interface are derived from tests performed under the ambient temperature, frcc_c_ck

frequency and VDD supply voltage conditions summarized in Table 24: General operating

conditions, with the following configuration:

•

Output speed is set to OSPEEDRy[1:0] = 11

•

Measurement points are done at CMOS levels: 0.5VDD

Refer to Section 6.3.15: I/O port characteristics for more details on the input/output

characteristics.

Asynchronous waveforms and timings

Figure 24 through Figure 27 represent asynchronous waveforms and Table 66 through

Table 73 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

•

Capcitive load CL = 30 pF

In all timing tables, the TKERCK is the fmc_ker_ck clock period.
