DLPC231SZEKQ1

Specialized ICS Overview

The DLPC231SZEKQ1 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 display resolution of 1358 x 566 pixels. The device operates within an ambient temperature range of -40°C to +105°C and utilizes a 324-NFBGA package. Key electrical parameters include power supply voltages of 1.1V, 1.8V, and 3.3V, with operating currents of 28.1 mA, 71 mA, and 201 mA respectively. It features a 600MHz SubLVDS interface and internal SRAM, eliminating the need for external memory.

Specialized ICS Feature Summary

• AEC-Q100 qualified for Grade 2 (-40°C to +105°C) with ISO 26262 functional safety support up to ASIL-B.
• Integrates an ARM Cortex-R4F processor with SECDED ECC and on-chip SRAM for image processing without external RAM.
• Supports video processing features including scaling, bezel adjustment (±50% vertical, ±10% horizontal), and gamma correction.
• Features a 600MHz SubLVDS DMD interface for low power and emission, along with spread spectrum clocking.

Specialized ICS Applications

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

Specialized ICS Procurement Notes

Verify the AEC-Q100 qualification status and ASIL-B functional safety documentation availability before integration. Confirm that the 324-NFBGA (ZEK) package dimensions align with the PCB layout requirements. Ensure the host system provides stable power rails at 1.1V, 1.8V, and 3.3V prior to deasserting the RESETZ signal to guarantee proper initialization.

Specialized ICS Selection Notes

Select the DLPC231SZEKQ1 when designing automotive interior displays requiring high dynamic range dimming and functional safety compliance. It is specifically optimized for use with DLP5530S-Q1 and DLP4620S-Q1 DMDs. Consider the internal SRAM capacity if external memory constraints exist. Verify compatibility with the TPS99000S-Q1 illumination controller for complete chipset functionality.

Specialized ICS Part Context

This component belongs to the DLPC23xS-Q1 family, which also includes the DLPC230S-Q1. The primary distinction lies in the package type: the DLPC231S uses a compact 15mm x 15mm NFBGA, whereas the DLPC230S uses a larger 23mm x 23mm BGA. Both share identical electrical specifications and functional capabilities for automotive DMD control.

Specialized ICS Replacement Considerations

The DLPC230S-Q1 serves as a pin-compatible alternative within the same family, differing only in the ZDQ (324-BGA) package compared to the ZEK (324-NFBGA) package of the DLPC231S-Q1. No other functional replacements are documented in the provided datasheet.
