6 - ELECTRICAL CHARACTERISTICS

6.1 - DC Characteristics

6.1.1 - Absolute Maximum Ratings

They are the same.

6.1.2 - DC Characteristics

6.1.2.1 - Operating Voltage

The ST10F269 appears like a 5V device externally but operates at a lower internal voltage thanks to a

voltage regulator.

Hardware Impacts

pins are named DC1 and DC2, respectively pins 56 and 17, and are used as de-coupling pins for the

internal core supply.

Software Impacts

None.

6.1.2.2 - Programming Voltage

The ST10F269 has a single voltage Flash Memory.

Hardware Impacts

The 12V input on the pin 84 is no longer needed.

Software Impacts

None.

6.1.2.3 - Miscellaneous

6.2 - AC characteristics at 25MHz

6.2.1 - Hardware Impact

None.

6.2.2 - Software Impact

None.
