IWR1642AQASABL

RF Detectors Overview

The IWR1642AQASABL is a single-chip 76- to 81-GHz millimeter-wave sensor manufactured by Texas Instruments. It integrates an RF transceiver, baseband processing, and microcontroller on one die. The device operates within the 76GHz to 81GHz frequency range. It utilizes a 161-pin FC/CSP package with dimensions of 10.4x10.4 mm. The component supports surface mount installation. Supply voltage ranges are specified as 1.71V to 1.89V and 3.15V to 3.45V. The operating temperature range spans from -40°C to +105°C. Moisture sensitivity level is rated at MSL 3 (168 hours).

RF Detectors Feature Summary

• Integrates a complete 76-81 GHz mmWave radar system including transmitter, receiver, and signal processing on a single chip.
• Provides high-resolution sensing capabilities for detecting object distance, velocity, and angle in complex environments.
• Features embedded digital signal processing cores to reduce host processor load and simplify system design.

RF Detectors Applications

• Automotive collision avoidance and blind spot detection systems
• Industrial robot navigation and obstacle avoidance
• Smart home presence detection and gesture recognition

RF Detectors Procurement Notes

Verify the specific suffix 'AASABL' against the manufacturer's official datasheet to confirm pinout, marking, and thermal specifications match the design requirements. Ensure the procurement channel provides valid traceability documentation. Confirm RoHS compliance status and moisture sensitivity handling procedures prior to soldering. Cross-reference the part number with the latest revision history to avoid obsolete manufacturing sites.

RF Detectors Selection Notes

Select this component when a compact, low-power solution for short-range radar sensing is required. It is suitable for applications needing integrated processing without external radar chips. Consider the 161-pin package constraints for PCB layout. Evaluate the -40°C to +105°C temperature range against environmental conditions. Compare power consumption metrics with alternative sensors if battery life is critical.

RF Detectors Part Context

This part belongs to the IWR1642 family of mmWave sensors from Texas Instruments. It shares architectural similarities with the AWR1642 but is optimized for industrial and consumer markets rather than automotive qualification. The IWR1642 series enables developers to implement radar-based solutions using standard development tools like the IWR1642BOOST evaluation module.

RF Detectors Replacement Considerations

The IWR1642AQAGABLR is a related variant within the same family, differing primarily in packaging type (TR vs Tray) and potentially minor electrical tolerances. Verify functional equivalence before substitution. No other direct cross-manufacturer replacements are documented in public sources.
