Doc ID 17050 Rev 8

5.3.24

Embedded reference voltage

The parameters given in Table 68 are derived from tests performed under ambient

temperature and VDD supply voltage conditions summarized in Table 11.

5.3.25

FSMC characteristics

Asynchronous waveforms and timings

Figure 53 through Figure 56 represent asynchronous waveforms and Table 69 through

Table 72 provide the corresponding timings. The results shown in these tables are obtained

with the following FSMC configuration:

●

AddressSetupTime = 1

●

AddressHoldTime = 1

●

DataSetupTime = 1

●

BusTurnAroundDuration = 0x0

In all timing tables, the THCLK is the HCLK clock period.
