XRA1202/1202P

8-BIT I2C/SMBUS GPIO EXPANDER WITH RESET

APRIL 2013

REV. 1.0.1

FEATURES

GENERAL DESCRIPTION

•

1.65V to 3.6V operating voltage

8 General Purpose I/Os (GPIOs)

5V tolerant inputs

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.

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

I²C/SMBus bus interface

■

I²C clock frequency up to 400kHz

Noise filter on SDA and SCL inputs

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.

■

Up to 16 I²C 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

Active-low reset input

The XRA1202/1202P are enhanced versions of the

PCA9538. The XRA1202 is pin and software

compatible with the PCA9538 (note: software

registers are compatible to the PCA9538, but the I²C

slave address is different).

Pin and software compatible with PCA9538

3kV HBM ESD protection per JESD22-A114F

200mA latch-up performance per JESD78B

The XRA1202 is available in 16-pin QFN and 16-pin

TSSOP packages. The XRA1202P is available in the

16-pin QFN package.

APPLICATIONS

•

Personal Digital Assistants (PDA)

Cellular Phones/Data Devices

Battery-Operated Devices

Global Positioning System (GPS)

Bluetooth
