LM8323JGR8AXMX/NOPB

Controllers Overview

The LM8323JGR8AXMX/NOPB is a mobile I/O companion integrated circuit manufactured by Texas Instruments. It supports key-scan, general-purpose I/O expansion, pulse-width modulation (PWM), and ACCESS.bus host interface functions. The device operates within a supply voltage range of 1.65 V to 5.5 V. It features an SPI bus interface for configuration and control. The component is designed for low-power applications in mobile devices.

Controllers Feature Summary

• Supports key-scan matrix scanning for input detection
• Provides general-purpose I/O expansion capabilities
• Integrates PWM outputs for peripheral control
• Functions as an ACCESS.bus host interface controller

Controllers Applications

• Mobile phone keypad and touch interface expansion
• Portable device I/O port extension
• ACCESS.bus compatible peripheral management in handheld systems

Controllers Procurement Notes

Verify the complete part number including the suffix /NOPB to ensure lead-free compliance and specific tape-and-reel packaging configuration. Confirm the J-grade temperature rating matches the intended operating environment requirements before finalizing procurement orders.

Controllers Selection Notes

Select this component when a single chip must handle multiple low-speed interface tasks including key scanning and I/O expansion in space-constrained mobile designs. Ensure the system voltage falls within the 1.65 V to 5.5 V range and that SPI communication lines are available for configuration.

Controllers Part Context

This part belongs to the LM8323 family of mobile I/O companions from Texas Instruments. It is specifically engineered to reduce component count in portable electronics by combining several discrete interface functions into one package. The device complements main processors by offloading simple input/output and bus management tasks.

Controllers Replacement Considerations

Direct pin-to-pin replacements may include other LM8323 variants with different suffixes such as LM8323JGR8AXM/NOPB or LM8323JGR8AXS/NOPB. Verify functional equivalence regarding ACCESS.bus support and key-scan capacity before substituting.
