XRA1202IL16-F

Overview

The XRA1202IL16-F is an 8-bit general-purpose input/output (GPIO) expander manufactured by MaxLinear, Inc. It features an I2C and SMBus interface for communication. The device operates within a voltage range of 1.7V to 5.5V and supports data rates up to 400 kHz. It is housed in a 16-QFN package with dimensions of 3x3 mm and a height of 0.90 mm. The component functions across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides eight bidirectional GPIO pins for system expansion
• Supports standard I2C and SMBus communication protocols
• Includes internal pull-up resistors on power-up

Applications

• Embedded systems requiring additional control lines
• Industrial automation control interfaces
• Consumer electronics peripheral management

Procurement Notes

Verify the specific suffix 'F' indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the package marking and pinout configuration match the 16-QFN specification before integration. Ensure supply chain sources provide valid traceability for automotive or industrial grade requirements if applicable.

Selection Notes

Select this component when an 8-bit expansion is required with I2C compatibility. Consider the 1.7V minimum operating voltage for low-power applications. Evaluate the 400 kHz speed limit against system timing requirements. Compare against the XRA1202P variant if enhanced ESD protection specifications are necessary for the target environment.

Part Context

This part belongs to the XRA1202 series of I/O expanders from MaxLinear. It complements other interface solutions like UART bridges and USB controllers within the company's portfolio. The QFN form factor allows for compact PCB layouts in space-constrained designs compared to larger packages.
