3 Description

The DLPC23x-Q1 DMD Display Controller for

automotive applications is used in chipsets for interior

applications such as HUD and exterior application

such as high resolution headlight. The DLP553x-Q1

chipset includes a 0.55” DMD and the DLP462x-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 realtime

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. 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.
