3 Description

The DLPC23x-Q1 digital micromirror display (DMD)

controller for automotive applications is used in

chipsets for interior applications such as HUD and

exterior application such as high resolution headlight.

The DLP5530-Q1 chipset includes a 0.55” DMD

and the DLP4621-Q1 chipset includes a 0.46

DMD. Both chipsets also include the TPS99000-Q1

System Management and Illumination controller. The

DLPC23x-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 TPS99000-Q1, the DLPC23x-

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.
