DLP4620SAFQXQ1

Specialized ICS Overview

The DLP4620SAFQXQ1 is an automotive-grade Digital Micromirror Device (DMD) featuring a 0.46-inch diagonal micromirror array with 960x960 resolution and a 7.6µm pitch. It operates within a -40°C to +105°C temperature range and supports bottom illumination for compact optical engine designs. The device utilizes a 600MHz SubLVDS interface for low-power data transmission and achieves a 10kHz refresh rate across extreme temperatures. Key electrical parameters include a VDD supply of 1.8V, total power dissipation of 1.045W, and operation in a 120-pin CLGA package.

• Automotive qualification compliant with AEC-Q100 standards
• Functional safety quality managed up to ISO 26262 ASIL-B
• Bottom illumination configuration for high efficiency
• Built-in self-test (BIST) for DMD memory cells

Specialized ICS Applications

• Augmented reality head-up displays (HUD)
• Digital cluster and navigation windshield displays
• Infotainment display systems

Specialized ICS Procurement Notes

Verify the specific suffix 'FQX' against the manufacturer's current datasheet to confirm pinout and packaging dimensions match the design requirements. Ensure that the ordering documentation explicitly references the DLPC231S-Q1 controller and TPS99000S-Q1 system management components as part of the required chipset architecture for proper functionality.

Specialized ICS Selection Notes

Select this component when designing wide aspect ratio automotive displays requiring retinal-limited HUD performance. The 2:1 aspect ratio and 0.9MP resolution support large driver eye boxes. Confirm compatibility with LED or laser illumination sources and ensure the optical system can handle the specified 10kHz refresh rate under extreme thermal conditions.

Specialized ICS Part Context

This device belongs to the DLP4620S-Q1 series of automotive digital micromirror devices. It is designed to function as part of a complete chipset solution, specifically intended for integration with the DLPC231S-Q1 DMD controller and the TPS99000S-Q1 system management and illumination controller to deliver high-performance visual output.

Specialized ICS Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Replacement requires validation of the complete chipset compatibility, including the specific controller and illumination management ICs defined by Texas Instruments.
