9 / 85 page ![]() STMPE16M31, STMPE24M31 Pin assignment Doc ID 16174 Rev 4 9/85 1.1 Power scheme The STMPE24M31/16M31 is powered by a 2.7- 5.5 V supply. An internal voltage regulator regulates this supply into 1.8 V for core operation. It is recommended to connect a 1 µF capacitor at VCC pin for filtering purpose. The VIO powers all GPIOs directly, if any LED driving is required on the GPIO, the VIO should be at least 3.3 V. Figure 5. Power supply scheme 1.2 Power states The STMPE24M31/16M31 operate in 3 states. Table 4 illustrates the capability of the device in each of the power states.
