The DLP5500 Digital Micromirror Device (DMD) is a digitally controlled MOEMS (micro-opto-electromechanical system) spatial light modulator (SLM). When coupled to an appropriate optical system, the DLP5500 can be used to modulate the amplitude, direction, and/or phase of incoming (illumination) light. Architecturally, the DLP5500 is a latchable, electrical-in/optical-out semiconductor device. This architecture makes the DLP5500 well suited for use in applications such as structured lighting, 3D optical metrology, Industrial & Medical imaging, microscopy, and spectroscopy. The compact physical size of the DLP5500 enables integration into portable equipment. The DLP5500 is one of three components in the DLP 0.55 XGA chip-set (see Figure 1). Proper function and operation of the DLP5500 requires that it be used in conjunction with the other components of the chip-set. The DLPC200 (TI literature number DLPS014) and DLPA200 (TI literature number DLPS015) control and coordinate the data loading and micromirror switching to guarantee reliable operation. Refer to DLP 0.55 XGA chip-set data sheet (TI literature number DLPZ004) for further details. DLPR200F is DLPC200 firmware code provided to enable Video and Structured Lighting Applicaions. To locate the latest version of the DLPR200F, go to www.ti.com and search keyword "DLPR200". Electrically, the DLP5500 consists of a two-dimensional array of 1-bit CMOS memory cells, organized in a square grid of 1024 memory cell columns by 768 memory cell rows. The CMOS memory array is written to on a column-by-column basis, over a 16-bit Low Voltage Differential Signaling (LVDS) double data rate (DDR) bus. Row addressing is handled via a serial control bus. The specific CMOS memory access protocol is handled by the DLPC200 Digital Controller. 1
