3 Description
•
The DLP3000 digital micromirror device (DMD) is a
digitally-controlled
micro-opto-electromechanical
system (MOEMS) spatial light modulator (SLM)
optimized for small form-factor applications. When
coupled to an appropriate optical system, the
DLP3000 can be used to modulate the amplitude and
direction of incoming light. The DLP3000 creates
highly flexible light patterns with speed, precision, and
efficiency.

Architecturally, the DLP3000 is a latchable, electricalin/optical-out semiconductor device. This architecture
makes the DLP3000 well-suited for use in
applications such as 3D scanning or metrology with
structured light, augmented reality, microscopy,
medical instruments, and spectroscopy. The compact
physical size of the DLP3000 is well-suited for
portable equipment where small form factor and lower
cost are important.
The compact package
complements the small size of LEDs to enable highlyefficient, robust light engines.
The DLP3000 is one of two devices in the DLP® 0.3
WVGA chipset. Proper function and reliable operation
of the DLP3000 requires that it be used in conjunction
with the DLPC300 controller. See the DLP 0.3 WVGA
chipset data sheet (DLPZ005) for further details.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device is not implied at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure above Recommended Operating Conditions for extended periods may affect device reliability.
All voltage values are with respect to the ground terminals VSS (ground). The following power supplies are all required to operate the
DMD: Voltages VSS, VCC, VREF, VOFFSET, VBIAS, and VRESET.
VOFFSET supply transients must fall within specified voltages.
To prevent excess current, the supply voltage delta |VBIAS - VOFFSET| must be less than specified limit.
Exposure of the DMD simultaneously to any combination of the maximum operating conditions for case temperature, differential
temperature, or illumination power density will reduce the device lifetime.
DMD Temperature is the worst-case of any test point shown in Figure 11, or the active array as calculated by the Micromirror Array
Temperature Calculation.
Ceramic package temperature as measured at test point 3 (TP 3) in Figure 11.

application-specific effects be considered as early as possible in the design cycle.
(4) Array Temperature is the worst-case of any test point shown in Figure 11, or the active array as calculated by the Micromirror Array
Temperature Calculation.
(5) Per Figure 1, the maximum operational array temperature should be derated based on the micromirror landed duty cycle that the DMD
experiences in the end application. Refer to Micromirror Landed-On/Landed-Off Duty Cycle for a definition of micromirror landed duty
cycle.

The DMD is designed to conduct absorbed and dissipated heat to the back of the package. The cooling system must be capable of
maintaining the package within the temperature range specified in the Recommended Operating Conditions. The total heat load on the
DMD is largely driven by the incident light absorbed by the active area; although other contributions include light energy absorbed by the
window aperture and electrical power dissipation of the array. Optical systems should be designed to minimize the light energy falling
outside the window clear aperture since any additional thermal load in this area can significantly degrade the reliability of the device.

6.9 Typical Characteristics
The DLP3000 DMD is controlled by the DLPC300 controller. The controller has two modes of operation. The first is Video
mode where the video source is displayed on the DMD. The second is Pattern mode, where the patterns are pre-stored in
flash memory and then streamed to the DMD. The allowed DMD pattern rate depends on which mode and bit-depth is
selected.

Measured relative to the plane formed by the overall micromirror array.
Parking the micromirror array returns all of the micromirrors to an essentially flat (0˚) state (as measured relative to the plane formed by
the overall micromirror array).
(3) When the micromirror array is parked, the tilt angle of each individual micromirror is uncontrolled.
(4) Additional variation exists between the micromirror array and the package datums.
(5) When the micromirror array is landed, the tilt angle of each individual micromirror is dictated by the binary contents of the CMOS
memory cell associated with each individual micromirror. A binary value of 1 results in a micromirror landing in an nominal angular
position of +12°. A binary value of 0 results in a micromirror landing in an nominal angular position of –12°.
(6) Represents the landed tilt angle variation relative to the nominal landed tilt angle.
(7) Represents the variation that can occur between any two individual micromirrors, located on the same device or located on different
devices.
(8) For some applications, it is critical to account for the micromirror tilt angle variation in the overall system optical design. With some
system optical designs, the micromirror tilt angle variation within a device may result in perceivable nonuniformities in the light field
reflected from the micromirror array. With some system optical designs, the micromirror tilt angle variation between devices may result in
colorimetry variations and/or system contrast variations.
(9) Performance as measured at the start of life.
(10) Non-operating micromirror is defined as a micromirror that is unable to transition nominally from the –12° position to +12° or vice versa.
(11) Measured relative to the package datums B and C, shown in the Mechanical, Packaging, and Orderable Information.
(12) The minimum or maximum DMD optical efficiency observed in a specific application depends on numerous application-specific design
variables, such as:
(a) Illumination wavelength, bandwidth/line-width, degree of coherence
(b) Illumination angle, plus angle tolerance
(c) Illumination and projection aperture size, and location in the system optical path
(d) Illumination overfill of the DMD micromirror array
(e) Aberrations present in the illumination source and/or path
(f) Aberrations present in the projection path
The specified nominal DMD optical efficiency is based on the following use conditions:
(a) Visible illumination (420 to 700 nm)
(b) Input illumination optical axis oriented at 24° relative to the window normal
(c) Projection optical axis oriented at 0° relative to the window normal
(d) ƒ / 3 illumination aperture
(e) ƒ / 2.4 projection aperture
Based on these use conditions, the nominal DMD optical efficiency results from the following four components:
(a) Micromirror array fill factor: nominally 92.5%
(b) Micromirror array diffraction efficiency: nominally 86%
(c) Micromirror surface reflectivity: nominally 88%
(d) Window transmission: nominally 97% (single pass, through two surface transitions)
(13) Does not account for the effect of micromirror switching duty cycle, which is application dependent. Micromirror switching duty cycle
represents the percentage of time that the micromirror is actually reflecting light from the optical illumination path to the optical projection
path. This duty cycle depends on the illumination aperture size, projection aperture size, and micromirror array update rate.
NOTE
TI assumes no responsibility for end-equipment optical performance. Achieving the
desired end-equipment optical performance involves making trade-offs between numerous
component and system design parameters. See the related application reports (listed in
Related Documentation) for guidelines.

DLPS022B – JANUARY 2012 – REVISED MARCH 2015
7.3 Feature Description
Electrically, the DLP3000 consists of a two-dimensional array of 1-bit CMOS memory cells, organized in a grid of
608 memory cell columns by 684 memory cell rows. The CMOS memory array is addressed on a column-bycolumn basis, over a 15-bit DDR bus. Addressing is handled via a serial control bus. The specific CMOS memory
access protocol is handled by the DLPC300 digital controller.
Optically, the DLP3000 consists of 415872 highly-reflective, digitally-switchable, micrometer-sized mirrors
(micromirrors) organized in a 2-D array. The micromirror array consists of 608 micromirror columns by 684
micromirror rows in diamond pixel configuration (Figure 9). Due to the diamond pixel configuration, the columns
of each odd row are offset by half a pixel from the columns of the even row.
Each aluminum micromirror is approximately 7.6 microns in size (see Micromirror Pitch in Figure 9) and is
switchable between two discrete angular positions: –12° and +12°. The angular positions are measured relative
to a 0° flat reference when the mirrors are parked in their inactive state, parallel to the array plane (see
Figure 10). The tilt direction is perpendicular to the hinge-axis. The on-state landed position is directed toward
the left side of the package (see DLP3000 Active Mirror Array, Micromirror Pitch, and Micromirror Hinge-Axis
Orientation in Figure 9).
Each individual micromirror is positioned over a corresponding CMOS memory cell. The angular position of a
specific micromirror is determined by the binary state (logic 0 or 1) of the corresponding CMOS memory cell
contents, after the mirror clocking pulse is applied. The angular position (–12° or +12°) of the individual
micromirrors changes synchronously with a micromirror clocking pulse, rather than being coincident with the
CMOS memory cell data update. Therefore, writing a logic 1 into a memory cell followed by a mirror clocking
pulse results in the corresponding micromirror switching to a +12° position. Writing a logic 0 into a memory cell
followed by a mirror clocking pulse results in the corresponding micromirror switching to a –12° position.
Updating the angular position of the micromirror array consists of two steps.
1. Update the contents of the CMOS memory.
2. Apply a mirror reset to all of the micromirror array. Mirror reset pulses are generated internally by the
DLP3000 DMD, with application of the pulses being coordinated by the DLPC300 controller. See Timing
Requirements timing specifications.
Around the perimeter of the 608 × 684 array of micromirrors is a uniform band of border micromirrors. The border
micromirrors are not user-addressable. The border micromirrors land in the –12° position after power is applied
to the device. There are 10 border micromirrors on each side of the 608 × 684 active array.

7.4 Device Functional Modes
DLP3000 is part of the chipset comprising of the DLP3000 DMD and DLPC300 display controller. To ensure
reliable operation, DLP3000 DMD must always be used with a DLPC300 display controller.
DMD functional modes are controlled by the DLPC300 digital display controller. See the DLPC300 data sheet
listed in Related Documentation.
7.5 Window Characteristics and Optics
NOTE
TI assumes no responsibility for image quality artifacts or DMD failures caused by optical
system operating conditions exceeding limits described previously.
7.5.1 Optical Interface and System Image Quality
TI assumes no responsibility for end-equipment optical performance. Achieving the desired end-equipment
optical performance involves making trade-offs between numerous component and system design parameters.
Optimizing system optical performance and image quality strongly relate to optical system design parameter
trades. Although it is not possible to anticipate every conceivable application, projector image quality and optical
performance is contingent on compliance to the optical system operating conditions described in the following
sections.
7.5.2 Numerical Aperture and Stray Light Control
The angle defined by the numerical aperture of the illumination and projection optics at the DMD optical area
should be the same. This angle should not exceed the nominal device mirror tilt angle unless appropriate
apertures are added in the illumination and/or projection pupils to block out flat-state and stray light from the
projection lens. The mirror tilt angle defines DMD capability to separate the "ON" optical path from any other light
path, including undesirable flat-state specular reflections from the DMD window, DMD border structures, or other
system surfaces near the DMD such as prism or lens surfaces. If the numerical aperture exceeds the mirror tilt
angle, or if the projection numerical aperture angle is more than two degrees larger than the illumination
numerical aperture angle, objectionable artifacts in the display’s border and/or active area could occur.
7.5.3 Pupil Match
TI’s optical and image quality specifications assume that the exit pupil of the illumination optics is nominally
centered within 2° (two degrees) of the entrance pupil of the projection optics. Misalignment of pupils can create
objectionable artifacts in the display’s border and/or active area, which may require additional system apertures
to control, especially if the numerical aperture of the system exceeds the pixel tilt angle.
7.5.4 Illumination Overfill
The active area of the device is surrounded by an aperture on the inside DMD window surface that masks
structures of the DMD device assembly from normal view. The aperture is sized to anticipate several optical
operating conditions. Overfill light illuminating the window aperture can create artifacts from the edge of the
window aperture opening and other surface anomalies that may be visible on the screen. The illumination optical
system should be designed to limit light flux incident anywhere on the window aperture from exceeding
approximately 10% of the average flux level in the active area. Depending on the particular system’s optical
architecture, overfill light may have to be further reduced below the suggested 10% level in order to be
acceptable.
7.6 Micromirror Array Temperature Calculation
Achieving optimal DMD performance requires proper management of the maximum DMD case temperature, the
maximum temperature of any individual micromirror in the active array, the maximum temperature of the window
aperture, and the temperature gradient between any two points on or within the package.
See the Absolute Maximum Ratings and Recommended Operating Conditions for applicable temperature limits.

Micromirror Array Temperature Calculation (continued)
The DMD is designed to conduct the absorbed and dissipated heat back to the series 220 package where it can
be removed by an appropriate system thermal management. The system thermal management must be capable
of maintaining the package within the specified operational temperatures at the Thermal test point location, see
Figure 11. The total heat load on the DMD is typically driven by the incident light absorbed by the active area;
although other contributions can include light energy absorbed by the window aperture, electrical power
dissipation of the array, and/or parasitic heating.
The temperature of the DMD case can be measured directly. For consistency, a thermal test point location is
defined, as shown in Figure 11.
Figure 11. Thermal Test Point Location
Micromirror array temperature cannot be measured directly. Therefore, it must be computed analytically from:
• Thermal test point location (see Figure 11)
• Package thermal resistance
• Electrical power dissipation
• Illumination heat load
The relationship between the micromirror array and the case temperature is provided by the following equations:
TArray = TCeramic + (QArray × RArray-To-Ceramic)
QArray = QElec + QIllum
QIllum = CL2W × SL

QArray = Total DMD array power (electrical + absorbed) (W)
RArray-to-Ceramic = Thermal resistance of DMD package from array to TC3 (°C/W)
QElec = Nominal electrical power (W)
QIllum = Absorbed illumination heat (W)
CL2W = Lumens-to-watts constant, estimated at 0.00293 W/lm, based on array characteristics. It assumes a
spectral efficiency of 300 lm/W for the projected light, illumination distribution of 83.7% on the active array, and
16.3% on the array border and window aperture.

Micromirror Array Temperature Calculation (continued)
These equations are based on traditional 1-chip DLP system with a total projection efficiency from the DMD to
the screen of 87%. An example calculation is provided in Equation 4 and Equation 5. DMD electrical power
dissipation varies and depends on the voltage, data rates, and operating frequencies. The nominal electrical
power dissipation used in this calculation is 0.15 W. Screen lumens is nominally 20 lm. The ceramic case
temperature at TC3 is 55°C. Using these values in the previous equations, the following values are computed:
QArray = QElec + CL2W × SL = 0.144 W + (0.00293 W/Lumen × 20 Lumen) = 0.2026 W
TArray = TCeramic + (QArray * RArray-To-Ceramic) = 55°C + (0.2026 W × 5 °C/W) = 56.01°C

7.7 Micromirror Landed-On/Landed-Off Duty Cycle
7.7.1 Definition of Micromirror Landed-On/Landed-Off Duty Cycle
The micromirror landed-on/landed-off duty cycle (landed duty cycle) denotes the amount of time (as a
percentage) that an individual micromirror is landed in the On–state versus the amount of time the same
micromirror is landed in the Off–state.
As an example, a landed duty cycle of 100/0 indicates that the referenced pixel is in the On–state 100% of the
time (and in the Off–state 0% of the time); whereas 0/100 would indicate that the pixel is in the Off–state 100% of
the time. Likewise, 50/50 indicates that the pixel is On 50% of the time and Off 50% of the time.
Note that when assessing landed duty cycle, the time spent switching from one state (ON or OFF) to the other
state (OFF or ON) is considered negligible and is thus ignored.
Since a micromirror can only be landed in one state or the other (On or Off), the two numbers (percentages)
always add to 100.
7.7.2 Landed Duty Cycle and Useful Life of the DMD
Knowing the long-term average landed duty cycle (of the end product or application) is important because
subjecting all (or a portion) of the DMD’s micromirror array (also called the active array) to an asymmetric landed
duty cycle for a prolonged period of time can reduce the DMD’s usable life.
Note that it is the symmetry/asymmetry of the landed duty cycle that is of relevance. The symmetry of the landed
duty cycle is determined by how close the two numbers (percentages) are to being equal. For example, a landed
duty cycle of 50/50 is perfectly symmetrical whereas a landed duty cycle of 100/0 or 0/100 is perfectly
asymmetrical.
7.7.3 Landed Duty Cycle and Operational Array Temperature
Operational Array Temperature and Landed Duty Cycle interact to affect the DMD’s usable life, and this
interaction can be exploited to reduce the impact that an asymmetrical Landed Duty Cycle has on the DMD’s
usable life. This is quantified in the de-rating curve shown in Figure 1. The importance of this curve is that:
• All points along this curve represent the same usable life.
• All points above this curve represent lower usable life (and the further away from the curve, the lower the
usable life).
• All points below this curve represent higher usable life (and the further away from the curve, the higher the
usable life).
In practice, this curve specifies the Maximum Operating Array Temperature that the DMD should be operated at
for a give long-term average Landed Duty Cycle.
7.7.4 Estimating the Long-Term Average Landed Duty Cycle of a Product or Application
During a given period of time, the Landed Duty Cycle of a given pixel follows from the image content being
displayed by that pixel.
For example, in the simplest case, when displaying pure-white on a given pixel for a given time period, that pixel
will experience a 100/0 Landed Duty Cycle during that time period. Likewise, when displaying pure-black, the
pixel will experience a 0/100 Landed Duty Cycle.
Between the two extremes (ignoring for the moment color and any image processing that may be applied to an
incoming image), the Landed Duty Cycle tracks one-to-one with the gray scale value, as shown in Table 2.

Accounting for color rendition (but still ignoring image processing) requires knowing both the color intensity (from
0% to 100%) for each constituent primary color (red, green, and/or blue) for the given pixel as well as the color
cycle time for each primary color, where “color cycle time” is the total percentage of the frame time that a given
primary must be displayed in order to achieve the desired white point.
During a given period of time, the landed duty cycle of a given pixel can be calculated as follows:
Landed Duty Cycle = (Red_Cycle_% × Red_Scale_Value) + (Green_Cycle_% × Green_Scale_Value) + (Blue_Cycle_% ×
Blue_Scale_Value)
(6)
Where:
Red_Cycle_%, Green_Cycle_%, and Blue_Cycle_%, represent the percentage of the frame time that Red,
Green, and Blue are displayed (respectively) to achieve the desired white point.
For example, assume that the red, green and blue color cycle times are 50%, 20%, and 30% respectively (in
order to achieve the desired white point), then the Landed Duty Cycle for various combinations of red, green,
blue color intensities would be as shown in Table 3.

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The DLP3000 along with the DLPC300 controller provides a solution for many applications including structured
light and video projection. The DMD is a spatial light modulator, which reflects 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 DLPC300. Applications of interest include 3D machine vision, 3D printing, and spectroscopy.
8.2 Typical Application
A typical embedded system application using the DLPC300 controller and a DLP3000 is shown in Figure 12. In
this configuration, the DLPC300 controller supports a 24-bit parallel RGB input, typical of LCD interfaces, from an
external source or processor. This system configuration supports still and motion video sources plus sequential
pattern mode. Refer to Related Documents for the DLPC300 digital controller data sheet.

9 Power Supply Recommendations
9.1 DMD Power Supply Requirements
The following power supplies are all required to operate the DMD: six voltage-level supplies (VSS,VCC, VREF,
VOFFSET, VBIAS, and VRESET). For reliable operation of DLP3000, the following power-supply sequencing
requirements must be followed.
CAUTION
Reliable performance of the DMD requires that the following conditions be met:
• The VCC, VREF, VOFFSET, VBIAS, and VRESET power supply inputs all be present
during operation.
• The VCC, VREF, VOFFSET, VBIAS, and VRESET power supplies be sequenced on and off
in the manner prescribed.
Repeated failure to adhere to the prescribed power-up and power-down procedures
may affect device reliability
9.2 DMD Power Supply Power-Up Procedure
Follow these steps to power-up the DMD power supply.
1. Power up VCC and VREF in any order.
2. Wait for VCC and VREF to each reach a stable level within their respective recommended operating ranges.
3. Power up VBIAS, VOFFSET, and VRESET in any order, provided that the maximum delta-voltage between VBIAS
and VOFFSET is not exceeded (see Absolute Maximum Ratings for details).
NOTE
During the power-up procedure, the DMD LVCMOS inputs should not be driven high until
after step 2 is completed. Power supply slew rates during power up are unrestricted,
provided that all other conditions are met.
9.3 DMD Power Supply Power-Down Procedure
Follow these steps to power-down the DMD power supply.
1. Command the chipset controller to execute a mirror-parking sequence. See the controller data sheet (listed
in Related Documentation) for details.
2. Power down VBIAS, VOFFSET, and VRESET in any order, provided that the maximum delta voltage between
VBIAS and VOFFSET is not exceeded (see Absolute Maximum Ratings for details).
3. Wait for VBIAS, VOFFSET, and VRESET to each discharge to a stable level within 4 V of the reference ground.
4. Power down VCC and VREF in any order.
NOTE
During the power-down procedure, the DMD LVCMOS inputs should be held at a level
less than VREF + 0.3 V. Power-supply slew rates during power down are unrestricted,
provided that all other conditions are met.

10.1.5 Routing Constraints
In order to meet the specifications listed in Table 9 and Table 10, typically the PCB designer must route these
signals manually (not using automated PCB routing software). In case of length matching requirements, the
longer signals should be routed in a serpentine fashion, keeping the number of turns to a minimum and the turn
angles no sharper than 45 degrees. Avoid routing long traces all around the PCB.

10.1.6 Termination Requirements
Table 11 lists the termination requirements for the DMD and mDDR interfaces.
For applications where the routed distance of the mDDR or DMD signal can be kept less than 0.75 inches, then
this signal is short enough not to be considered a transmission line and should not need a series terminating
resistor.
