Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality.
The DLP7000UV devices require they be coupled with the DLPC410 controller to provide a reliable solution for many different applications. The DMDs are spatial light modulators which reflect incoming light from an illumination source to one of two directions, with the primary direction being into a projection collection optic. Each application is derived primarily from the optical architecture of the system and the format of the data coming into the DLPC410. Applications of interest include lithography, 3D Printing, medical systems, and compressive sensing.
TI assumes no responsibility for end-equipment reflectivity performance. Achieving the desired end-equipment reflectivity performance involves making trade-offs between numerous component and system design parameters. DMD reflectivity characteristics over UV exposure times are represented in Figure 18.

DMD reflectivity includes micromirror surface reflectivity and window transmission. The DMD was characterized for DMD reflectivity using a broadband light source (200-W metal-halide lamp). Data is based off of a 2.3-W/cm2 UV exposure at the DMD surface (363-nm peak output) using a 363-nm high-pass filter between the light source and the DMD. (Contact your local Texas Instruments representative for additional information about power density measurements and UV filter details.)
Optimal, long-term performance of the digital micromirror device (DMD) can be affected by various application parameters. Below is a list of some of these application parameters and includes high level design recommendations that may help extend relative reflectivity from time zero:
All applications using the DLP7000UV chipset require both the controller and the DMD components for operation. The system also requires an external parallel flash memory device loaded with the DLPC410 Configuration and Support Firmware. The chipset has several system interfaces and requires some support circuitry. The following interfaces and support circuitry are required:
The DLP7000UV XGA chipset offers developers a convenient way to design a wide variety of industrial, medical, telecom and advanced display applications by delivering maximum flexibility in formatting data, sequencing data, and light patterns.
The DLP7000UV XGA chipset includes the following four components: DMD Digital Controller (DLPC410), EEPROM (DLPR410), DMD Micromirror Driver (DLPA200), and a DMD (DLP7000UV).

Reliable function and operation of DLP7000UV XGA chipsets require the components be used in conjunction with each other. This document describes the proper integration and use of the DLP7000UV XGA chipset components.
The DLP7000UV XGA chipset can be combined with a user programmable Application FPGA (not included) to create high performance systems.
The DLP7000UV DMD is designed with a window which allows transmission of Ultra-Violet (UV) light. This makes it well suited for UV applications requiring fast, spatially programmable light patterns using the micromirror array. UV wavelengths can affect the DMD differently than visible wavelengths. There are system level considerations which should be leveraged when designing systems using this DMD.
