Overview
The XRA1201IG24-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 an interrupt output capability and provides 16 general-purpose input/output pins with an open-drain configuration. It is housed in a QFN-EP-24 package suitable for surface mount applications. The component functions reliably across an industrial temperature range from -40°C to +85°C.
Feature Summary
- Provides 16 configurable general-purpose digital input and output channels via I2C or SMBus interface
- Includes dedicated interrupt output pin for efficient event-driven system monitoring
- Supports low-voltage operation compatible with various logic levels
Applications
- Embedded systems requiring expanded I/O capabilities
- Industrial control panels needing remote GPIO management
- Consumer electronics utilizing space-constrained PCB layouts
Procurement Notes
Verify the specific suffix and manufacturer details against official datasheets before integration, as component specifications may vary between original Exar and current MaxLinear production runs. Confirm end-of-life status and availability constraints through authorized distributors to ensure long-term project viability.
Selection Notes
Select this component when a high-density GPIO solution is required in a compact footprint. Ensure the host controller supports I2C or SMBus protocols at speeds up to 400 kHz. Verify that the system power rail aligns with the 1.65 V to 3.6 V operating range and that thermal dissipation requirements fit within the QFN-EP-24 package limits.
Part Context
This part belongs to the XRA1201 series of I/O expanders, originally developed by Exar Corporation before its acquisition by MaxLinear. It serves as a bridge between microcontrollers and peripheral devices, allowing for flexible system architecture design without consuming additional processor pins.
Replacement Considerations
Potential substitutes include the XRA1203 for variants with reset functionality or the PCA6416A from NXP Semiconductors. Verify pin compatibility and register mapping differences before implementing any cross-manufacturer replacement.
