DLPC231ZEKRQ1

Specialized ICS Overview

The DLPC231ZEKRQ1 is an automotive-grade digital micromirror device (DMD) controller designed for interior and exterior display applications requiring functional safety. It supports DLP553xS-Q1 and DLP462xS-Q1 chipsets, integrating an ARM Cortex-R4F processor with SECDED ECC. The device features a 600MHz SubLVDS interface, embedded SRAM eliminating external memory needs, and video processing capabilities including scaling and bezel adjustment. It operates within a temperature range of -40°C to +105°C and is qualified under AEC-Q100 Grade 2.

Specialized ICS Feature Summary

• AEC-Q100 qualified for automotive applications (-40°C to +105°C)
• Integrates ARM Cortex-R4F processor with error correction
• Supports DLP553xS-Q1 and DLP462xS-Q1 chipset combinations
• Includes internal SRAM for image processing without external RAM

Specialized ICS Applications

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

Specialized ICS Procurement Notes

Verify the specific suffix ZEK against the datasheet to confirm the 324-pin nFBGA package variant. Ensure the design accounts for the required external pull-ups and pull-downs specified in the pin configuration tables for proper initialization and operation.

Specialized ICS Selection Notes

Select this controller when designing for DLP553xS-Q1 or DLP462xS-Q1 DMDs. Confirm compatibility with the TPS99000S-Q1 system management controller. Verify that the host interface requirements align with the available SPI or I2C options.

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 DLPC231 uses a compact 15mm x 15mm nFBGA, whereas the DLPC230 utilizes a larger 23mm x 23mm BGA.

Specialized ICS Replacement Considerations

The DLPC230S-Q1 serves as a functional alternative if the larger package footprint is acceptable. Both devices share identical electrical characteristics and software compatibility.
