DMDs are spatial light modulators that reflect incoming light from an illumination source to one of two directions, with the primary direction being into a projection or collection optic. Each application is derived primarily from the optical architecture of the system and the format of the data coming into the DLPC4430 display controller. Typical applications using the DLP801RE DMD include smart projectors, enterprise projectors, large venue projectors and digital signage.

DMD power-up and power-down sequencing is strictly controlled by the DLPC4430 display controller through the DLPA300. Refer to Section 9 for power-up and power-down specifications. For reliable operation, the DLP801RE DMD must always be used with DLPC4430 display controller, a DLPA100 PMIC/Motor driver, and a DLPA300 Micromirror Driver.
