3 Description

The DLPC23xS-Q1 digital micromirror device (DMD)

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 DLP5530S-Q1 chipset includes a 0.55” DMD

and the DLP4620S-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. Onchip

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.

SubLVDS 600MHz 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.
