Electrical characteristics
STM32H745xI/G
160/252
DS12923 Rev 1
Refer to Section 6.3.16: I/O port characteristics for more details on the input/output alternate
function characteristics.
Asynchronous waveforms and timings
Figure 27 through Figure 29 represent asynchronous waveforms and Table 75 through
Table 82 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
•
Capacitive load CL = 30 pF
In all timing tables, the TKERCK is the fmc_ker_ck clock period.
