7 I/O PORT CHARACTERISTICS

Unless otherwise specified, the parameters given as below Table.

For detail information of I/O injection parameters and conditions, please refer to

STM32F205RG I/0 manual.

Table7.1 I/O static characteristics

1. FT = Five-volt tolerant. In order to sustain a voltage higher than VDD+0.3 the internal pull-

up/pull-down resistors must be disabled.

2. Hysteresis voltage between Schmitt trigger switching levels. Based on characterization, not

tested in production.

3. With a minimum of 100 mV.

4. Leakage could be higher than max. if negative current is injected on adjacent pins.

5. Pull-up and pull-down resistors are designed with a true resistance in series with a

switchable PMOS/NMOS. This MOS/NMOS contribution to the series resistance is minimum

(~10% order).
