NXLS96120AESR2

Microprocessors Overview

The NXLS96120AESR2 is a single-channel inertial sensor designed for automotive safety applications. It supports DSI3, PSI5 Version 2.1, SPI, and I²C interfaces. The device measures acceleration along the X-axis with medium g ranges from ±15.5 g to ±150 g nominal full-scale range. It operates within a temperature range of -40 °C to 125 °C. Key features include high-side bus switch output drivers, programmable time slots with 1 µs resolution, selectable baud rates of 125 kBd or 189 kBd, and 10- or 16-bit data options. It integrates an embedded DSP with up to a fourth-order low-pass filter.

Microprocessors Feature Summary

• Supports multiple communication protocols including DSI3, PSI5 Version 2.1, SPI, and I²C for flexible system integration.
• Features an embedded digital signal processor (DSP) providing fully programmable digital filtering capabilities.
• Includes diagnostic modes such as background diagnostics during periodic data collection and discovery mode for physical location identification.
• Designed with wettable flanks on the QFN package to enable visual inspection of solder joints.

Microprocessors Applications

• Airbag crash sensing systems
• Vehicle stability control systems
• Seat belt pretensioner activation

Microprocessors Procurement Notes

Verify the specific suffix 'R2' indicates reel packaging when sourcing. Confirm the manufacturer transition status, as NXP MEMS sensors have been transitioned to STMicroelectronics. Ensure compliance with current automotive qualification standards such as AEC-Q100 and ISO26262 requirements for the target application safety level.

Microprocessors Selection Notes

Select this component for single-axis lateral or vertical acceleration measurement in airbag systems. Choose based on required interface compatibility, specifically PSI5 V2.1 or DSI3. Consider the medium g range suitability for the specific crash pulse requirements. Verify the operating temperature range meets the installation environment constraints.

Microprocessors Part Context

This part belongs to the NXLS9xxx0 family of single-channel inertial sensors. These devices are recommended for new designs starting in Q1-2026, replacing older FXLS9x series products. The family utilizes proprietary UMEMS sensing technology combined with a signal conditioning ASIC in a compact 4 mm x 4 mm x 1.45 mm QFN package.

Microprocessors Replacement Considerations

FXLS90xxxx and FXLS93xxxx products continue to be supported in production until inventory depletion. For new designs, the NXLS9xxx0 family is the recommended replacement path. Verify pinout and software compatibility when migrating from legacy NXP MEMS accelerometer families.
