DLPC231SZEKRQ1

Specialized ICS Overview

The DLPC231SZEKRQ1 is an automotive-grade Digital Micromirror Device (DMD) controller from Texas Instruments, designed for functional safety applications up to ASIL-B. It supports DLP553xS-Q1 and DLP462xS-Q1 chipsets with a 1358 x 566 pixel resolution capability. The device features a 600MHz SubLVDS interface, embedded ARM Cortex-R4F processor with ECC, and internal SRAM. Operating temperatures range from -40°C to +105°C. Power supplies include 1.01V–1.19V, 1.65V–1.95V, and 3.02V–3.58V rails. It utilizes a 324-pin NFBGA package.

Specialized ICS Feature Summary

• AEC-Q100 qualified for Grade 2 (-40°C to +105°C ambient)
• Supports DLP553xS-Q1 and DLP462xS-Q1 automotive chipsets
• Integrated ARM Cortex-R4F processor with SECDED ECC
• 600MHz SubLVDS DMD interface for low power and emission

Specialized ICS Applications

• Wide field of view and augmented reality head-up displays (HUD)
• Digital cluster windshield displays
• Navigation and infotainment windshield displays

Specialized ICS Procurement Notes

Verify the ZEK suffix indicates the 324-pin nFBGA package (15mm x 15mm). Confirm the 'R1' suffix corresponds to Tape & Reel packaging. Ensure the 'Q1' designation matches AEC-Q100 automotive qualification requirements for your specific system design.

Specialized ICS Selection Notes

Select this controller when designing interior or exterior automotive displays requiring functional safety compliance. It pairs with TPS99000S-Q1 illumination controllers. Verify compatibility with DLP5530S-Q1 or DLP4620S-Q1 DMDs based on required display size and resolution.

Specialized ICS Part Context

This component belongs to the DLPC23xS-Q1 family, which includes the DLPC230S-Q1. The DLPC231S-Q1 variant specifically uses the ZEK package code, distinguishing it from the larger ZDQ package used in the DLPC230S-Q1. Both share identical functional specifications but differ in physical footprint.

Specialized ICS Replacement Considerations

The DLPC230SZEKRQ1 is a functional alternative within the same family but utilizes a different 324-pin BGA package (ZDQ, 23mm x 23mm) compared to the DLPC231SZEKRQ1's nFBGA (ZEK, 15mm x 15mm). Pinout and board layout are not compatible.
