Application Information (continued)
• Cumulative incident illumination – limiting the total hours of UV illumination exposure when the DMD is not
actively steering UV light in the application. For example, a design might include a shutter to block the
illumination or LED illumination where the LEDs can be strobed off during periods not requiring UV exposure.
• Micromirror landed duty cycle – applying a 50/50 duty cycle pattern during periods where operational patterns
are not required.

9.2.1 Design Requirements
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:
• DLPC410 system interfaces:
– Control interface
– Trigger interface
– Input data interface
– Illumination interface
– Reference clock
• DLP7000UV interfaces:
– DLPC410 to DLP7000UV digital data
– DLPC410 to DLP7000UV control interface
– DLPC410 to DLP7000UV micromirror reset control interface
– DLPC410 to DLPA200 micromirror driver
– DLPA200 to DLP7000UV micromirror reset
Device Description:
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.
