XRA1201/1201P

16-BIT I2C/SMBUS GPIO EXPANDER

SEPTEMBER 2011

REV. 1.0.0

FEATURES

GENERAL DESCRIPTION

• 1.65V to 3.6V operating voltage

• 16 General Purpose I/Os (GPIOs)

• 5V tolerant inputs

The XRA1201/1201P is a 16-bit GPIO expander with

an I C/SMBus interface.

After power-up, the

XRA1201 has internal 100K ohm pull-up resistors on

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

XRA1201P has 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 XRA1201/1201P 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 XRA1201/1201P are enhanced versions of other

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

• Pin and software compatible with PCA9535,

TCA9535, MAX7312 (XRA1201)

The XRA1201 is pin and software compatible with the

PCA9535, TCA9535 and MAX7312. The XRA1201P

is pin and software compatible with the CAT9555,

PCA9555, TCA9555, MAX7311 and MAX7318.

• Pin and software compatible with CAT9555,

PCA9555, TCA9555, MAX7311 and MAX7318

(XRA1201P)

The XRA1201/1201P are available in 24-pin QFN

and 24-pin TSSOP packages.

• 3kV HBM ESD protection per JESD22-A114F

• 200mA latch-up performance per JESD78B

APPLICATIONS

• Personal Digital Assistants (PDA)

• Cellular Phones/Data Devices

• Battery-Operated Devices

• Global Positioning System (GPS)

• Bluetooth
