XRA1200PIL16-F

Overview

The XRA1200PIL16-F is an 8-bit I2C/SMBus GPIO expander in a 16-pin QFN package. It operates at 1.65V to 3.6V with inputs tolerant to 5V. The device features individually programmable internal pull-up resistors, polarity inversion, and interrupt generation on rising/falling edges. It supports up to 400kHz clock frequency and offers open-drain active low interrupt output. The part includes three-state control for outputs and input filtering capabilities.

Feature Summary

Individually configurable general-purpose I/Os with internal pull-up resistor enablement
Programmable interrupt generation based on rising or falling edge detection
Open-drain active low interrupt output with configurable clearing mechanisms
Output three-state control capability for power management scenarios

Applications

Personal Digital Assistants (PDA)
Cellular Phones/Data Devices
Battery-Operated Devices
Global Positioning System (GPS)
Bluetooth

Procurement Notes

Verify the specific ordering suffix 'F' indicates Green/RoHS compliance as documented. Confirm the 'P' designation ensures internal pull-ups are enabled upon power-up, distinguishing it from the standard XRA1200 variant. Ensure the QFN-16 package matches the required thermal and mechanical constraints for the target PCB layout.

Selection Notes

Select this component when pin and software compatibility with CAT9554 or PCA9554 is required. Choose the XRA1200P variant specifically if known input states are necessary immediately after power-up due to its default internal pull-up configuration. Verify that the 1.65V to 3.6V supply range aligns with the system voltage rails.

Part Context

This part is part of the XRA1200/1200P family, which serves as enhanced versions of earlier 8-bit GPIO expanders. It maintains pin and software compatibility with industry-standard parts like the CAT9534, PCA9534, CAT9554, and PCA9554. The 'P' suffix denotes the version with default internal pull-ups enabled, while the 'IL16' specifies the QFN-16 package and operating temperature range.
