XRA1202P - 8-BIT I2C/SMBUS GPIO EXPANDER

Download the XRA1202P datasheet PDF. This datasheet also covers the XRA1202 variant, as both devices belong to the same 8-bit i2c/smbus gpio expander family and are provided as variant models within a single manufacturer datasheet.

General Description

The XRA1202/1202P is an 8-bit GPIO expander with an I2C/SMBus interface.

After power-up, the XRA1202 has internal 100K ohm pull-up resistors on each I/O pin that can be individually enabled.

Key Features

  • 1.65V to 3.6V operating voltage.
  • 8 General Purpose I/Os (GPIOs).
  • 5V tolerant inputs.
  • Maximum stand-by current of 1uA at +1.8V.
  • I2C/SMBus bus interface s I2C clock frequency up to 400kHz s Noise filter on SDA and SCL inputs s Up to 16 I2C Slave Addresses.
  • Individually programmable inputs s Internal pull-up resistors s Polarity inversion s Individual interrupt enable s Rising edge and/or Falling edge interrupt s Input filter.
  • Individu.

XRA1202/1202P 8-BIT I2C/SMBUS GPIO EXPANDER WITH RESET APRIL 2013 REV. 1.0.1 GENERAL DESCRIPTION The XRA1202/1202P is an 8-bit GPIO expander with an I2C/SMBus interface. After power-up, the XRA1202 has internal 100K ohm pull-up resistors on each I/O pin that can be individually enabled. The XRA1202P has the internal pull-up 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 XRA1202/1202P 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.
