MxL82200

The MxL82200 and MxL82210 are 8-bit GPIO expanders with an I2C/SMBus interface. After power-up, the MxL82200 has internal 100K ohm pull-up resistors on each I/O pin that can be individually enabled. The MxL82210 has internal pullup resistors enabled upon power-up in case it is necessary for the inputs to be in a known state.

In addition, the GPIOs on the MxL82200 and MxL82210 can individually be controlled and configured. As outputs, the GPIOs can be outputs that are high, low, or in three-state mode. The three-state mode feature is useful for applications where the power is removed from the remote devices, but they may still be connected to the GPIO expander.

As inputs, the internal pull-up resistors can be enabled or disabled and the input polarity can be inverted. The interrupt behavior is configurable. It can be set to trigger on a rising edge, falling edge, or both edges. The interrupt

condition is cleared either when the input returns to its original state or when the current input state is read.

The MxL82200 and MxL82210 are enhanced versions of other 8-bit GPIO expanders with an I2C/SMBus interface. The MxL82200 is pin and software compatible with the CAT9534 and PCA9534. The MxL82210 is pin and software compatible with the CAT9554 and PCA9554.

The MxL82200 and MxL82210 are also pin compatible with the PCA9554A and TCA9554A. The MxL82200 and MxL82210 are available in 16-pin TSSOP and 16-pin QFN packages.
