Texas Instruments DLPC230-Q1 DLP® Automotive DMD Controllers

Texas Instruments DLPC230-Q1 DLP® Automotive DMD Controllers are part of two DMD chipsets, the DLP5530-Q1 (interior display applications, such as HUD) and DLP5531-Q1 (exterior lighting applications, such as high-resolution headlight). Both these chipsets include a 0.55” DMD and the TPS99000-Q1 System Management and Illumination controller.

The TI DLPC230-Q1 DLP Automotive DMD Controllers integrates an embedded processor with error code correction (SECDED ECC), allowing host control and real-time feedback, on-chip diagnostics, and system monitoring functions. The need for external DRAM is eliminated via the included on-chip SRAM. With the TPS99000-Q1, the DLPC230-Q1 supports high dynamic range dimming of over 5000:1 for HUD applications. Sub-LVDS 600MHz DMD interface allows high DMD refresh rates to generate seamless and brilliant digital images while simultaneously reducing radiated emissions.
