PCA9555PWRE4 Frequently Asked Questions (FAQ)
-
The PCA9555PWRE4 can support I2C bus frequencies up to 400 kHz, but it is recommended to operate at 100 kHz or lower for reliable operation.
-
The PCA9555PWRE4 is configured to operate in 16-bit mode by default. To operate in 8-bit mode, the A0 and A1 pins must be tied to VCC or GND to select the desired mode.
-
The PCA9555PWRE4 can sink or source up to 25 mA of current on its GPIO pins, but it is recommended to limit the current to 10 mA or less to ensure reliable operation.
-
The PCA9555PWRE4 can be reset by pulling the RESET pin low for at least 1 ms. This will reset the device to its default state.
-
No, the PCA9555PWRE4 is designed to operate with a 1.65V to 5.5V power supply, but it is not recommended to operate at 5V as it may exceed the maximum rating of some internal components.
