The DMD is a 0.65 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 DLP650LE DMD is part of the chipset comprising of the DLP650LE DMD, the DLPC4420 display controller, the DLPA100 power and motor driver and the DLPA200 micromirror driver. To ensure reliable operation, the DLP650LE DMD must always be used with the DLPC4420 display controller, the DLPA100 power and motor driver and the DLPA200 micromirror driver.
