3 Description

The DLPC23xS-Q1 DMD Display Controller for

automotive applications is used in chipsets for interior

and exterior display applications with a functional

safety requirement (such as augmented reality

HUDs and windshield clusters). The DLP553xS-Q1

chipset includes a 0.55” DMD and the DLP462xS-Q1

chipset includes a 0.46 DMD. Both chipsets also

include the TPS99000S-Q1 System Management and

Illumination controller. The DLPC23xS-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. On-chip SRAM is included to remove

the need for external DRAM. Combined with the

TPS99000S-Q1, the DLPC23xS-Q1 supports high

dynamic range dimming of over 5000:1 for HUD

applications. Sub-LVDS 600-MHz DMD interface

allows high DMD refresh rates to generate seamless

and brilliant digital images, while simultaneously

reducing radiated emissions.

To aid in the design and manufacture of automotive

qualified projectors based on DLP technology,

there are a number of established optical module

manufacturers and design houses that can be

leveraged to support your design.
