162/245

DS12500 Rev 1

In the user application, the number of I/O pins which can drive current must be limited to

respect the absolute maximum rating specified in Section 0.2. In particular:

•

The sum of the currents sourced by all the I/Os on VDD, plus the maximum Run mode

consumption of the MCU sourced on VDD, cannot exceed the absolute maximum rating

∑IVDD (see Table 11).

•

The sum of the currents sunk by all the I/Os on VSS plus the maximum Run mode

consumption of the MCU sunk on VSS cannot exceed the absolute maximum rating

∑IVSS (see Table 11).

Output voltage levels

Unless otherwise specified, the parameters given in Table 49 are derived from tests

performed under ambient temperature and VDD supply voltage conditions summarized in

Table 13: General operating conditions. All I/Os are CMOS and TTL compliant.

1. The IIO current sourced or sunk by the device must always respect the absolute maximum rating specified in Table 10:

Voltage characteristics, and the sum of the currents sourced or sunk by all the I/Os (I/O ports and control pins) must always

respect the absolute maximum ratings ∑IIO.

2. TTL and CMOS outputs are compatible with JEDEC standards JESD36 and JESD52.

3. Guaranteed by design.
