Texas Instruments DLPC230S-Q1 DLP® Automotive DMDs

Texas Instruments DLPC230S-Q1 DLP^® Automotive DMDs is part of the DLP5530S-Q1 chipset used for interior display applications with a functional safety requirement (such as augmented reality HUDs and windshield clusters). The chipset also includes a 0.55” DMD and the TPS99000S-Q1 System Management and Illumination controller.

The TI DLPC230S-Q1 integrates an embedded processor with error code correction (SECDED ECC), enabling host control and real-time feedback, on-chip diagnostics, and system monitoring functions. An on-chip SRAM is included to remove the requirement for external DRAM.

The DLPC230S-Q1, combined with the TPS99000S-Q1, supports high dynamic range dimming of over 5000:1 for HUD applications. The Sub-LVDS 600MHz DMD interface allows high DMD refresh rates to generate seamless and brilliant digital images while simultaneously reducing radiated emissions.
