The DMD is a 0.66-inch diagonal spatial light modulator which consists of an array of highly reflective aluminum micromirrors. The DMD is an electrical input, optical output micro-electrical-mechanical system (MEMS). The electrical interface is low voltage differential signaling (LVDS). The DMD consists of a two-dimensional array of 1-bit CMOS memory cells. The array is organized in a grid of M memory cell columns by N memory cell rows. Refer to Section 6.2. The positive or negative deflection angle of the micromirrors can be individually controlled by changing the address voltage of underlying CMOS addressing circuitry and micromirror reset signals (MBRST).

The DLP660TE DMD is part of the chipset comprising of the DLP660TE DMD, the DLPC4420 display controller and the DLPA100 power and motor driver. For reliable operation, the DLP660TE DMD must always be used with the DLPC4420 display controller and the DLPA100 power and motor driver.
