1. Guaranteed by design, not tested in production.

2. If VDD is below 3 V, the code execution is guaranteed above the VIT- and VIT+ thresholds. RAM content is

kept. The EEPROM programming sequence must not be initiated.

VCAP external capacitor

Stabilization for the main regulator is achieved connecting an external capacitor CEXT to the

VCAP pin. CEXT is specified in Table 26. Care should be taken to limit the series inductance

to less than 15 nH.

1. Legend: ESR is the equivalent series resistance and ESL is the equivalent inductance.

Supply current characteristics

The current consumption is measured as described in Figure 9 on page 58 and Figure 10

on page 59.

If not explicitly stated, general conditions of temperature and voltage apply.
