XRA1200/1200P

8-BIT I2C/SMBUS GPIO EXPANDER

SEPTEMBER 2011

REV. 1.0.0

FEATURES

GENERAL DESCRIPTION

• 1.65V to 3.6V operating voltage

• 8 General Purpose I/Os (GPIOs)

• 5V tolerant inputs

The XRA1200/1200P is an 8-bit GPIO expander with

an I C/SMBus interface.

After power-up, the

XRA1200 has internal 100K ohm pull-up resistors on

each I/O pin that can be individually enabled. The

XRA1200P have the internal pull-up resistors

enabled upon power-up in case it is necessary for the

inputs to be in a known state.

• Maximum stand-by current of 1uA at +1.8V

• I C/SMBus bus interface

■ I C clock frequency up to 400kHz

In addition, the GPIOs on the XRA1200/1200P 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.

■ Noise filter on SDA and SCL inputs

■ Up to 32 I C Slave Addresses

• Individually programmable inputs

■ Internal pull-up resistors

■ Polarity inversion

As inputs, the internal pull-up resistors can be

enabled or disabled and the input polarity can be

inverted. The interrupt can be programmed for

■ Individual interrupt enable

■ Rising edge and/or Falling edge interrupt

■ Input filter

different behaviors.

The interrupts can be

programmed to generate an interrupt on the rising

edge, falling edge or on both edges. The interrupt

can be cleared if the input changes back to its original

state or by reading the current state of the inputs.

• Individually programmable outputs

■ Output Level Control

■ Output Three-State Control

• Open-drain active low interrupt output

The XRA1200/1200P are enhanced versions of other

8-bit GPIO expanders with an I C/SMBus interface.

• Pin and software compatible with CAT9534,

CAT9554, PCA9534, and PCA9554

The XRA1200 is pin and software compatible with the

CAT9534 and PCA9534. The XRA1200P is pin and

software compatible with the CAT9554 and

• 3kV HBM ESD protection per JESD22-A114F

• 200mA latch-up performance per JESD78B

APPLICATIONS

PCA9554.

The XRA1200/1200P are also pin

compatible with the PCA9554A and TCA9554A.

The XRA1200/1200P are available in 16-pin QFN

and 16-pin TSSOP packages.

• Personal Digital Assistants (PDA)

• Cellular Phones/Data Devices

• Battery-Operated Devices

• Global Positioning System (GPS)

• Bluetooth
