Electrical characteristics
STM32U5Axxx
314/382
DS13543 Rev 1
Refer to Section 5.3.14: I/O port characteristics for more details on the input/output
characteristics.
Asynchronous waveforms and timings
Figure 55 to Figure 58 represent asynchronous waveforms and Table 125 to Table 132
provide the corresponding timings. The results shown in these tables are obtained with the
following FMC configuration:
•
AddressSetupTime (ADDSET) = 0x1
•
AddressHoldTime (ADDHLD) = 0x1
•
ByteLaneSetup (NBLSET) = 0x1
•
DataSetupTime (DATAST) = 0x1 (except for asynchronous NWAIT mode,
DataSetupTime = 0x5)
•
DataHoldTime (DATAHLD) = 0x1 (0x0 for write operation)
•
BusTurnAroundDuration = 0x0
•
Capacitive load CL = 30 pF
In all timing tables, the THCLK is the HCLK clock period.
