STR720 - ELECTRICAL CHARACTERISTICS
385/401
28.8 AC and DC characteristics
The parameters listed in the following tables represent the electrical characteristics of
STR720 general purpose I/O pins and external memory interfaces (EMI and SDRAM). On
Table 99 the static characteristics are reported.
1.
VDD(all) = 1.80 V ± 10%, VDD3(all) = 3.30 V ± 10%, TA = -40 / +85 °C unless otherwise specified.
In the following table the dynamic characteristics of general purpose I/O pins and external
memory interfaces (EMI and SDRAM are reported). For a description of external memory
