AT91SAM7S32 Preliminary
These conditions and derating process apply to the following paragraphs: Clock Characteris-
tics, Embedded Flash Characteristics and JTAG/ICE Timings.
All delays are given as typical values under the following conditions:
•
•
•
•
•
•
The minimum and maximum values given in the AC characteristics tables of this datasheet
take into account process variation and design. In order to obtain the timing for other condi-
tions, the following equation should be used:
