A8003SMHN1/9E34AFJ

Overview

The A8003SMHN1/9E34AFJ is a component within the NXP USA Inc. portfolio, identified by the specific ordering suffix E34AFJ which denotes a reel packaging configuration. The base part number A8003SMHN1/9 indicates a device from the P3H series of I3C interface devices. This series functions as an I3C Hub designed to expand connectivity for application processors. The component supports the MIPI I3C standard, providing a scalable utility and control bus solution that integrates attributes from I2C-bus and SPI interfaces to deliver a unified, high-performance, low-power interface.

Feature Summary

• Functions as an I3C Hub with multiple controller and target ports for system expansion
• Supports MIPI I3C basic protocol with in-band interrupt (IBI) capabilities
• Provides dynamic address assignment and backward compatibility with I2C-bus implementations
• Enables bidirectional voltage level translation and data rate throughput up to 12.5 Mbit/s

Applications

• Connecting peripherals to application processors in mobile computers
• Industrial building automation systems requiring scalable control buses
• Consumer home audio applications needing low-power interface solutions

Procurement Notes

Verify the complete ordering code including the E34AFJ suffix to ensure correct reel packaging specifications. Confirm the specific hub port configuration required for the design, as the P3H series includes variants with different default or debug configurations for controller and target ports. Cross-reference the datasheet for exact pinout and electrical characteristics relevant to the specific revision.

Selection Notes

Select this component when an I3C Hub is required to connect multiple targets to a single controller while maintaining I2C compatibility. Consider the P3H2840xHN or P3H2841xHN variants if eight target ports are needed, or the P3H2440xHN/P3H2441xHN for four target ports. Ensure the system voltage levels align with the translator capabilities specified in the datasheet.

Part Context

This part belongs to the NXP I3C Interface Devices family, specifically the Hubs category. It is designed to work alongside other I3C components such as buffers, translators, and multiplexers. The P3H series addresses the need for flexible upgrade paths from traditional I2C and SPI implementations to the more efficient I3C standard.

Replacement Considerations

Direct replacements include other models within the P3H series, such as P3H2840xHN, P3H2841xHN, P3H2440xHN, or P3H2441xHN, depending on the required number of target ports and configuration type. Verify pin-to-pin compatibility and electrical specifications before substitution.
