Overview
The XRA1201PIG24-F is a 16-bit I2C/SMBus GPIO expander manufactured by MaxLinear. It operates within a supply voltage range of 1.65 V to 3.6 V and supports clock frequencies up to 400 kHz. The device features open-drain outputs with a maximum output current of 160 mA and includes an interrupt output capability. It is housed in a QFN-EP-24 package, designed for surface-mount installation, and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Provides 16 general-purpose input/output channels controlled via I2C or SMBus interfaces
- Includes dedicated interrupt output pin for efficient event-driven communication
- Supports low-voltage operation from 1.65 V to 3.6 V with open-drain output configuration
Applications
- Embedded systems requiring additional GPIO ports via serial interfaces
- Industrial control panels needing remote I/O expansion
- Consumer electronics utilizing I2C-based peripheral management
Procurement Notes
Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and check for End-of-Life notices, as availability may be restricted. Ensure the specific suffix matches required packaging and temperature grades before procurement.
Selection Notes
Select this component when 16 bidirectional I/O lines are required with I2C compatibility. Consider the QFN-EP-24 package for thermal performance and space constraints. Verify that the host controller supports the necessary SMBus/I2C protocols and interrupt handling mechanisms.
Part Context
This part belongs to the XRA1201 series of GPIO expanders from MaxLinear (formerly Exar). It serves as a bridge between high-speed microcontrollers and slower peripheral devices, allowing system designers to extend I/O capabilities without consuming additional processor pins on the main controller.
Replacement Considerations
Check for direct pin-compatible alternatives within the same family, such as the XRA1201IL24TR-F, which shares similar electrical characteristics but may differ in packaging or reel specifications. Verify functional equivalence before substitution.
