Overview
The XRA1402IG16-F is an 8-bit SPI GPIO expander manufactured by MaxLinear. It operates within a supply voltage range of 1.65 V to 3.6 V and supports a maximum clock frequency of 15 MHz. The device features interrupt output capability and is housed in a TSSOP-16 surface-mount package. It functions across an industrial temperature range from -40°C to +85°C, with a total output current capacity of 160 mA and power dissipation rated at 200 mW.
Feature Summary
- Provides eight general-purpose input/output lines accessible via a standard Serial Peripheral Interface (SPI) bus.
- Includes an interrupt output pin to signal state changes on the I/O ports without continuous polling.
- Supports low-voltage operation suitable for systems requiring 1.65 V to 3.6 V power supplies.
Applications
- General-purpose I/O expansion for embedded microcontroller systems
- Adding push-button inputs or LED indicators to space-constrained designs
- Interface extension in portable electronic devices
Procurement Notes
Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance details as specified in official documentation. Check for potential supply chain restrictions or regional sales limitations before procurement planning.
Selection Notes
Select this component when SPI interface availability is required for I/O expansion. Ensure the design accommodates the TSSOP-16 package dimensions. Verify that the system logic levels align with the 1.65 V to 3.6 V operating range.
Part Context
