Electrical characteristics

For an efficient and easy tracking, numbering has been added to each electrical parameter.

Device features are split into categories, see Table 5, and each of them is represented by a

Letter (A, B, C, etc); all parameters will be completely identified by a letter and three digit

number (e.g. B.125, C.096…) for their whole lifetime.

New inserted parameters will continue with the numbering of the related category, no matter

of where they are placed.

To facilitate insertion, the last number inserted for each category is also reported in Table 5.

Due to these rules and taking into account that deleted parameter numbers will be no more

reassigned, numbering inside each category may be not sequential.



All the electrical parameters reported in the following sections are evaluated with L99UDL01

in Normal Mode.
