DESCRIPTION
I6
Manufacturing test enable signal. This signal should be connected directly to ground on the
PCB for normal operation.
PARKZ
C13
I6
DMD fast PARK control (active low Input) (hysteresis buffer). PARKZ must be set high to
enable normal operation. PARKZ should be set high prior to releasing RESETZ (that is, prior to
the low-to-high transition on the RESETZ input). PARKZ should be set low for a minimum of 40
µs before any power is removed from the DLPC343x such that the fast DMD PARK operation
can be completed. Note for PARKZ, fast PARK control should only be used when loss of power
is eminent and beyond the control of the host processor (for example, when the external power
source has been disconnected or the battery has dropped below a minimum level). The longest
lifetime of the DMD may not be achieved with the fast PARK operation. The longest lifetime is
achieved with a normal PARK operation. Because of this, PARKZ is typically used in
conjunction with a normal PARK request control input through GPIO_08. The difference being
that when the host sets PROJ_ON low, which connects to both GPIO_08 and the DLPA2000
PMIC chip, the DLPC343x takes much longer than 40 µs to park the mirrors. The DLPA2000
holds on all power supplies, and keep RESETZ high, until the longer mirror parking has
completed. This longer mirror parking time, of up to 500 µs, ensures the longest DMD lifetime
and reliability.
The DLPA2000 monitors power to the DLPC343x and detects an eminent power loss condition
and drives the PARKZ signal accordingly.

This pin must be tied to ground, through an external 8-kΩ, or less, resistor for normal operation.
Failure to tie this pin low during normal operation will cause startup and initialization problems.
I6
DLPC343x power-on reset (active low input) (hysteresis buffer). Self-configuration starts when a
low-to-high transition is detected on RESETZ. All ASIC power and clocks must be stable before
this reset is de-asserted. Note that the following signals will be tri-stated while RESETZ is
asserted:
SPI0_CLK, SPI0_DOUT, SPI0_CSZ0,
SPI0_CSZ1, and GPIO(19:00)
External pullups or downs (as appropriate) should be added to all tri-stated output signals listed
(including bidirectional signals to be configured as outputs) to avoid floating ASIC outputs
during reset if connected to devices on the PCB that can malfunction. For SPI, at a minimum,
any chip selects connected to the devices should have a pullup.
Unused bidirectional signals can be functionally configured as outputs to avoid floating ASIC
inputs after RESETZ is set high.
The following signals are forced to a logic low state while RESETZ is asserted and
corresponding I/O power is applied:
LED_SEL_0, LED_SEL_1 and DMD_DEN_ARSTZ
No signals will be in their active state while RESETZ is asserted.
Note that no I2C activity is permitted for a minimum of 500 ms after RESETZ (and PARKZ) are
set high.

If operation does not call for an external pullup and there is no external logic that might overcome the weak internal pulldown resistor,
then this I/O can be left open or unconnected for normal operation. If operation does not call for an external pullup, but there is external
logic that might overcome the weak internal pulldown resistor, then an external pulldown resistor is recommended to ensure a logic low.
External pullup resistor must be 8 kΩ, or less, for pins with internal pullup or down resistors.
If operation does not call for an external pullup and there is no external logic that might overcome the weak internal pulldown resistor,
then the TSTPT I/O can be left open/ unconnected for normal operation. If operation does not call for an external pullup, but there is
external logic that might overcome the weak internal pulldown resistor, then an external pulldown resistor is recommended to ensure a
logic low.

DESCRIPTION
DMD_DEN_ARSTZ
B1
O2
DMD driver enable (active high)/ DMD reset (active low). Assuming the
corresponding I/O power is supplied, this signal will be driven low after the DMD is
parked and before power is removed from the DMD. If the 1.8-V power to the
DLPC343x is independent of the 1.8-V power to the DMD, then TI recommends a
weak, external pulldown resistor to hold the signal low in the event DLPC343x
power is inactive while DMD power is applied.

DESCRIPTION
CMP_OUT
A12
I6
Successive approximation ADC comparator output (DLPC343x Input). Assumes a successive
approximation ADC is implemented with a WPC light sensor and/or a thermistor feeding one input of
an external comparator and the other side of the comparator is driven from the ASIC’s CMP_PWM pin.
Should be pulled-down to ground if this function is not used. (hysteresis buffer)
CMP_PWM
A15
O1
Successive approximation comparator pulse-duration modulation (output). Supplies a PWM signal to
drive the successive approximation ADC comparator used in WPC light-to-voltage sensor applications.
Should be left unconnected if this function is not used.
O9
Host interrupt (output)
This signal has two primary uses. The first use is to indicate when DLPC343x auto-initialization is in
progress and most importantly when it completes. The second is to indicate when service is requested
(that is an interrupt request).
The DLPC343x tri-states this output during reset and assumes that an external pullup is in place to
drive this signal to its inactive state.

(which can be 1.8, 2.5, or 3.3 V). External I2C pullups must be connected to an equal or higher supply
voltage, up to a maximum of 3.6 V (a lower pullup supply voltage would not likely satisfy the VIH
specification of the slave I2C input buffers).

LED_ENABLE = 1 (enabled), the ASIC is free to control the LED SEL signals as it desires. There is
however a 100-ms delay after LED_ENABLE transitions from low-to-high before the interlock is
released.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltage values are with respect to GND.
Overlap currents, if allowed to continue flowing unchecked, not only increase total power dissipation in a circuit, but degrade the circuit
reliability, thus shortening its usual operating life.

These supplies have multiple valid ranges.
These I/O supply ranges are wider to facilitate additional filtering.
The operating ambient temperature range assumes 0 forced air flow, a JEDEC JESD51 junction-to-ambient thermal resistance value at
0 forced air flow (RθJA at 0 m/s), a JEDEC JESD51 standard test card and environment, along with min and max estimated power
dissipation across process, voltage, and temperature. Thermal conditions vary by application, which will impact RθJA. Thus, maximum
operating ambient temperature varies by application.
(a) Ta_min = Tj_min – (Pd_min × RθJA) = –30°C – (0.0 W × 30.3°C/W) = –30°C

For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953.
Thermal coefficients abide by JEDEC Standard 51. RθJA is the thermal resistance of the package as measured using a JEDEC defined
standard test PCB. This JEDEC test PCB is not necessarily representative of the DLPC350 PCB and thus the reported thermal
resistance may not be accurate in the actual product application. Although the actual thermal resistance may be different , it is the best
information available during the design phase to estimate thermal performance.
Example: (0.5 W) × (0.2 °C/W) ≈ 1.00°C temperature rise.

Programmable host and flash I/O are at minimum voltage (that is 1.8 V) for this typical scenario.
Max currents column use typical motion video as the input. The typical currents column uses SMPTE color bars as the input.
Some applications (that is, high-resolution 3D) may be forced to use 1-oz copper to manage ASIC package heat.
For the typical cases, all pins using 1.8 V are tied together as are 1.1-V pins, and the current specified is for the collective 1.8-V and 1.1V current.
Assumes typical case power PVT condition = nominal process, typical voltage, typical temperature (55°C junction). WVGA resolution.

The I/O pin TSTPT_6 enables the ASIC to use two different oscillator frequencies through a pullup control at initial ASIC power-up. If a
pullup is applied to this pin then a 16.0-MHz oscillator option must be used instead of the 24-MHz option shown.
The frequency accuracy for MOSC is ±200 PPM. (This includes impact to accuracy due to aging, temperature, and trim sensitivity.) The
MOSC input cannot support spread spectrum clock spreading.

The minimum total vertical blanking is defined by the following equation: tp_tvb(min) = 6 + [6 × Max(1, Source_ALPF/ DMD_ALPF)] lines
where:
(a) SOURCE_ALPF = Input source active lines per frame
(b) DMD_ALPF = Actual DMD used lines per frame supported
Total horizontal blanking is driven by the max line rate for a given source which will be a function of resolution and orientation. The
following equation can be applied for this: tp_thb = Roundup[(1000 × ƒclock)/ LR] – APPL
where:
(a) ƒclock = Pixel clock rate in MHz
(b) LR = Line rate in kHz
(c) APPL is the number of active pixels per (horizontal) line.
(d) If tp_thb is calculated to be less than tp_hbp + tp_hfp then the pixel clock rate is too low or the line rate is too high, and one or both
must be adjusted.

Standard SPI protocol is to transmit data on the falling edge of SPI_CLK and capture data on the rising edge. The DLPC343x does
transmit data on the falling edge, but it also captures data on the falling edge rather than the rising edge. This provides support for SPI
devices with long clock-to-Q timing. DLPC343x hold capture timing has been set to facilitate reliable operation with standard external
SPI protocol devices.
With the above output timing, DLPC343x provides the external SPI device 8.2-ns input set-up and 8.2-ns input hold, relative to the rising
edge of SPI_CLK.
This range include the 200 ppm of the external oscillator (but no jitter).

7 Parameter Measurement Information
7.1 HOST_IRQ Usage Model
•
•
•
•
•
While reset is applied HOST_IRQ will reset to tri-state (an external pullup pulls the line high).
HOST_IRQ will remain tri-state (pulled high externally) until the microprocessor boot completes. While the
signal is pulled high, this indicates that the ASIC is performing boot-up and auto-initialization.
As soon as possible after boot-up, the microprocessor will drive HOST_IRQ to a logic high state to indicate
that the ASIC is continuing to perform auto-initialization (no real state change occurs on the external signal)
Upon completion of auto-initialization, software will set HOST_IRQ to a logic low state to indicate the
completion of auto-initialization. (At the falling edge, the system is said to enter the INIT_DONE state.)
After auto-initialization completes, HOST_IRQ is used to generate a logic high interrupt pulse to the host
through software control. (This interrupt indicates that the ASIC has detected an error condition or otherwise
requires service.)
RESETZ
500 ms max
The first falling edge of HOST_IRQ
indicates auto-initialization done.
(ERR IRQ)
HOST_IRQ

Pullup)
(INIT_BUSY)
3 µs min

I2C access to DLPC343x should not start until
HOST_IRQ goes low (this should occur within 500 ms
from the release of RESETZ.
An active high pulse on HOST_IRQ following the
initialization period indicates an error condition
was detected. The source of the error is reported
in the system status.

The user must stay within specifications for all source interface parameters such as max clock rate and max line rate.
The max DMD size for all rows in the table is 854 × 480.
To achieve the ranges stated, the composer-created firmware used must be defined to support the source parameters used.
These interfaces are supported with the DMD sequencer sync mode command (3Bh) set to auto.
Bits / Pixel does not necessarily equal the number of data pins used on the DLPC343x. Fewer pins are used if multiple clocks are used
per pixel transfer.
Frame rates below 10.00 Hz have not been tested by TI.

8 Detailed Description
8.1 Overview
The DLPC343x is the display controller for the DLP2010 (.2 WVGA) DMD. DLPC343x is part of the chipset
comprising DLPC343x controller, DLP2010 (.2 WVGA) DMD, and DLPA2000 PMIC/LED driver. All three
components of the chipset must be used in conjunction with each other for reliable operation of the DLP2010 (.2
WVGA) DMD. The DLPC343x display controller provides interfaces and data/image processing functions that are
optimized for small form factor and power-constrained display applications. Applications include projection within
cell phones, camera, camcorders and tablets, pico projectors, wearable displays, and digital signage. Standalone
projectors must include a separate front-end chip to interface to the outside world (for example, video decoder,
HDMI receiver, triple ADC, or USB I/F chip).

8.3 Feature Description
8.3.1 Interface Timing Requirements
This section defines the timing requirements for the external interfaces for the DLPC343x ASIC.
8.3.1.1 Parallel Interface
The parallel interface complies with standard graphics interface protocol, which includes a vertical sync signal
(VSYNC_WE), horizontal sync signal (HSYNC_CS), optional data valid signal (DATAEN_CMD), a 24-bit data
bus (PDATA), and a pixel clock (PCLK). The polarity of both syncs and the active edge of the clock are
programmable. Figure 4 shows the relationship of these signals. The data valid signal (DATAEN_CMD) is
optional in that the DLPC343x provides auto-framing parameters that can be programmed to define the data
valid window based on pixel and line counting relative to the horizontal and vertical syncs.
In addition to these standard signals, an optional side-band signal (PDM_CVS_TE) is available, which allows
periodic frame updates to be stopped without losing the displayed image. When PDM_CVS_TE is active, it acts
as a data mask and does not allow the source image to be propagated to the display. A programmable PDM
polarity parameter determines if it is active high or active low. This parameter defaults to make PDM_CVS_TE
active high; if this function is not desired, then it should be tied to a logic low on the PCB. PDM_CVS_TE is
restricted to change only during vertical blanking.

Feature Description (continued)
NOTE
VSYNC_WE must remain active at all times (in lock-to-VSYNC mode) or the display
sequencer will stop and cause the LEDs to be turned off.
8.3.2 Serial Flash Interface
DLPC343x uses an external SPI serial flash memory device for configuration support. The minimum required
size is dependent on the desired minimum number of sequences, CMT tables, and splash options while the
maximum supported is 16 Mb.
For access to flash, the DLPC343x uses a single SPI interface operating at a programmable frequency
complying to industry standard SPI flash protocol. The programmable SPI frequency is defined to be equal to
180 MHz/N, where N is a programmable value between 5 to 127 providing a range from 36.0 to 1.41732 MHz.
Note that this results in a relatively large frequency step size in the upper range (for example, 36 MHz, 30 MHz,
25.7 MHz, 22.5 MHz, and so forth) and thus this must be taken into account when choosing a flash device.
The DLPC343x supports two independent SPI chip selects; however, the flash must be connected to SPI chip
select zero (SPI0_CSZ0) because the boot routine is only executed from the device connected to chip select
zero (SPI0_CSZ0). The boot routine uploads program code from flash to program memory, then transfers control
to an auto-initialization routine within program memory. The DLPC343x asserts the HOST_IRQ output signal high
while auto-initialization is in progress, then drives it low to signal its completion to the host processor. Only after
auto-initialization is complete will the DLPC343x be ready to receive commands through I2C.
The DLPC343x should support any flash device that is compatible with the modes of operation, features, and
performance as defined in Table 3 and Table 4.

(that is expansion status byte)
The DLPC343x only supports single-byte status register R/W command execution, and thus may not be
compatible with flash devices that contain an expansion status byte. However, as long as expansion status
byte is considered optional in the byte 3 position and any write protection control in this expansion status
byte defaults to unprotected, then the device should be compatible with DLPC343x.
To support flash devices with program protection defaults of either enabled or disabled, the DLPC343x always
assumes the device default is enabled and goes through the process of disabling protection as part of the bootup process. This process consists of:
• A write enable (WREN) instruction executed to request write enable, followed by
• A read status register (RDSR) instruction is then executed (repeatedly as needed) to poll the write enable
latch (WEL) bit
• After the write enable latch (WEL) bit is set, a write status register (WRSR) instruction is executed that writes
0 to all 8-bits (this disables all programming protection)
Prior to each program or erase instruction, the DLPC343x issues:
• A write enable (WREN) instruction to request write enable, followed by

The specific instruction OpCode and timing compatibility requirements are listed in Table 6 and Table 5. Note
however that DLPC343x does not read the flash’s electronic signature ID and thus cannot automatically adapt

The timing values are related to the specification of the flash device itself, not the DLPC343x.
The DLPC343x does not drive the HOLD or WP (active low write protect) pins on the flash device, and thus these pins should be tied to
a logic high on the PCB through an external pullup.
The DLPC343x supports 1.8-, 2.5-, or 3.3-V serial flash devices. To do so, VCC_FLSH must be supplied with the
corresponding voltage. Table 6 contains a list of 1.8-, 2.5-, and 3.3-V compatible SPI serial flash devices
supported by DLPC343x.

The flash supply voltage must match VCC_FLSH on the DLPC343x. Special attention needs to be paid when ordering devices to be
sure the desired supply voltage is attained as multiple voltage options are often available under the same base part number.
Beware when considering Numonyx (Micron) serial flash devices as they typically do not have the 4KB sector size needed to be
DLPC343x compatible.
All of these flash devices appear compatible with the DLPC343x, but only those marked with yes in the DVT column have been
validated on the EVM3430 reference design. Those marked with no can be used at the ODM’s own risk.
8.3.3 Serial Flash Programming
Note that the flash can be programmed through the DLPC343x over I2C or by driving the SPI pins of the flash
directly while the DLPC343x I/O are tri-stated. SPI0_CLK, SPI0_DOUT, and SPI0_CSZ0 I/O can be tri-stated by
holding RESETZ in a logic low state while power is applied to the DLPC343x. Note that SPI0_CSZ1 is not tristated by this same action.
8.3.4 SPI Signal Routing
The DLPC343x is designed to support two SPI slave devices on the SPI0 interface, specifically, a serial flash
and the DLPA2000. This requires routing associated SPI signals to two locations while attempting to operate up
to 36 MHz. Take special care to ensure that reflections do not compromise signal integrity. To this end, the
following recommendations are provided:
• The SPI0_CLK PCB signal trace from the DLPC343x source to each slave device should be split into
separate routes as close to the DLPC343x as possible. In addition, the SPI0_CLK trace length to each device
should be equal in total length.
• The SPI0_DOUT PCB signal trace from the DLPC343x source to each slave device should be split into
separate routes as close to the DLPC343x as possible. In addition, the SPI0_DOUT trace length to each
device should be equal in total length(use the same strategy as SPI0_CLK).
• The SPI0_DIN PCB signal trace from each slave device to the point where they intersect on their way back to
the DLPC343x should be made equal in length and as short as possible. They should then share a common
trace back to the DLPC343x.
• SPI0_CSZ0 and SPI0_CSZ1 need no special treatment because they are dedicated signals which drive only
one device.
8.3.5 I2C Interface Performance
Both DLPC343x I2C interface ports support 100-kHz baud rate. By definition, I2C transactions operate at the
speed of the slowest device on the bus, thus there is no requirement to match the speed grade of all devices in
the system.
8.3.6 Content-Adaptive Illumination Control
Content-adaptive illumination control (CAIC) is an image processing algorithm that takes advantage of the fact
that in common real-world image content most pixels in the images are well below full scale for the for the R, G,
and B digital channels being input to the DLPC343x. As a result of this the average picture level (APL) for the
overall image is also well below full scale, and the system’s dynamic range for the collective set of pixel values is
not fully utilized. CAIC takes advantage of this headroom between the source image APL and the top of the
available dynamic range of the display system.

CAIC evaluates images frame by frame and derives three unique digital gains, one for each of the R, G, and B
color channels. During CAIC image processing, each gain is applied to all pixels in the associated color channel.
CAIC derives each color channel’s gain that is applied to all pixels in that channel so that the pixels as a group
collectively shift upward and as close to full scale as possible. To prevent any image quality degradation, the
gains are set at the point where just a few pixels in each color channel are clipped. Figure 15 and Figure 16
show an example of the application of CAIC for one color channel.
Figure 15. Input Pixels Example
Figure 16. Displayed Pixels After CAIC Processing
Figure 16 shows the gain that is applied to a color processing channel inside the DLPC343x. CAIC will also
adjust the power for the R, G, and B LED. For each color channel of an individual frame, CAIC will intelligently
determine the optimal combination of digital gain and LED power. The decision regarding how much digital gain
to apply to a color channel and how much to adjust the LED power for that color is heavily influenced by the
software command settings sent to the DLPC343x for configuring CAIC.
As CAIC applies a digital gain to each color channel independently, and adjusts each LED’s power
independently, CAIC also makes sure that the resulting color balance in the final image matches the target color
balance for the projector system. Thus, the effective displayed white point of images is held constant by CAIC
from frame to frame.

DLPS038B – JULY 2014 – REVISED FEBRUARY 2016
Since the R, G, and B channels can be gained up by CAIC inside the DLPC343x, the LED power can be turned
down for any color channel until the brightness of the color on the screen is unchanged. Thus, CAIC can achieve
an overall LED power reduction while maintaining the same overall image brightness as if CAIC was not used.
Figure 17 shows an example of LED power reduction by CAIC for an image where the R and B LEDs can be
turned down in power.
CAIC can alternatively be used to increase the overall brightness of an image while holding the total power for all
LEDs constant. In summary, when CAIC is enabled CAIC can operate in one of two distinct modes:
• Power Reduction Mode – holds overall image brightness constant while reducing LED power
• Enhanced Brightness Mode – holds overall LED power constant while enhancing image brightness
Figure 17. CAIC Power Reduction Mode (for Constant Brightness)
8.3.7 Local Area Brightness Boost
Local area brightness boost (LABB), is an image processing algorithm that adaptively gains up regions of an
image that are dim relative to the average picture level. Some regions of the image will have significant gain
applied, and some regions will have little or no gain applied. LABB evaluates images frame by frame and derives
the local area gains to be used uniquely for each image. Since many images have a net overall boost in gain
even if some parts of the image get no gain, the overall perceived brightness of the image is boosted.
Figure 18 shows a split screen example of the impact of the LABB algorithm for an image that includes dark
areas.

LABB works best when the decision about the strength of gains used is determined by ambient light conditions.
For this reason, there is an option to add an ambient light sensor which can be read by the DLPC343x during
each frame. Based on the sensor readings, LABB will apply higher gains for bright rooms to help overcome any
washing out of images. LABB will apply lower gains in dark rooms to prevent over-punching of images.
8.3.8 94- to 120-Hz 3-D Display Operation
The DLPC343x supports 94- to 120-Hz 3-D display operation, but is limited to:
• Only parallel interfaces (all pixel formats are supported)
• Only non-interlaced image inputs
• 122.4 Hz is maximum supported frame rate
• Un-packed, frame sequential, 3-D format (that is each 100- or 120-Hz source frame contains a single, full
resolution, eye frame separated by VSYNCs, where an eye frame contains image data for a single left or right
eye; not both)
Each DMD frame is displayed at the source frame rate in the order it is received. It is assumed that a front-end
device ahead of the DLPC343x will convert all 3-D sources to the 3-D format defined previously and will provide
any needed left or right eye selection control directly to the DLPC343x 3DR input pin.
8.3.9 DMD (Sub-LVDS) Interface
The DLPC343x ASIC DMD interface consists of a HS 1.8-V sub-LVDS output only interface with a maximum
clock speed of 600-MHz DDR and a LS SDR (1.8-V LVCMOS) interface with a fixed clock speed of 120 MHz.
The DLPC343x sub-LVDS interface supports a number of DMD display sizes, and as a function of resolution, not
all output data lanes are needed as DMD display resolutions decrease in size. With internal software selection,
the DLPC343x also supports a limited number of DMD interface swap configurations that can help board layout
by remapping specific combinations of DMD interface lines to other DMD interface lines as needed. Table 7
shows the four options available for the DLP2010 (.2 WVGA) DMD specifically. Any unused DMD signal pairs
should be left unconnected on the final board design.

8.3.10 DLPC343x System Design Consideration – Application Notes
System power regulation: It is acceptable for VDD_PLLD and VDD_PLLM to be derived from the same regulator
as the core VDD, but to minimize the AC noise component they should be filtered as recommended in the PCB
Layout Guidelines for Internal ASIC PLL Power.
8.3.11 Calibration and Debug Support
The DLPC343x contains a test point output port, TSTPT_(7:0), which provides selected system calibration
support as well as ASIC debug support. These test points are inputs while reset is applied and switch to outputs
when reset is released. The state of these signals is sampled upon the release of system reset and the captured
value configures the test mode until the next time reset is applied. Each test point includes an internal pulldown
resistor, thus external pullups must be used to modify the default test configuration. The default configuration
(x000) corresponds to the TSTPT_(7:0) outputs remaining tri-stated to reduce switching activity during normal
operation. For maximum flexibility, an option to jumper to an external pullup is recommended for TSTPT_(2:0).
Pullups on TSTPT_(6:3) are used to configure the ASIC for a specific mode or option. TI does not recommend
adding pullups to TSTPT_(7:3) because this has adverse affects for normal operation. This external pullup is only
sampled upon a 0-to-1 transition on the RESETZ input, thus changing their configuration after reset is released
will not have any effect until the next time reset is asserted and released. Table 8 defines the test mode selection
for one programmable scenario defined by TSTPT(2:0).

8.3.12 DMD Interface Considerations
The sub-LVDS HS interface waveform quality and timing on the DLPC343x ASIC is dependent on the total length
of the interconnect system, the spacing between traces, the characteristic impedance, etch losses, and how well
matched the lengths are across the interface. Thus, ensuring positive timing margin requires attention to many
factors.
As an example, DMD interface system timing margin can be calculated as follows:
Setup Margin = (DLPC343x output setup) – (DMD input setup) – (PCB routing mismatch) – (PCB SI degradation)
Hold-time Margin = (DLPC343x output hold) – (DMD input hold) – (PCB routing mismatch) – (PCB SI degradation)
(1)
where PCB SI degradation is signal integrity degradation due to PCB affects which includes such things as
Simultaneously Switching Output (SSO) noise, cross-talk and Inter-symbol Interference (ISI) noise.
(2)
DLPC343x I/O timing parameters as well as DMD I/O timing parameters can be found in their corresponding data
sheets. Similarly, PCB routing mismatch can be budgeted and met through controlled PCB routing. However,
PCB SI degradation is a more complicated adjustment.
In an attempt to minimize the signal integrity analysis that would otherwise be required, the following PCB design
guidelines are provided as a reference of an interconnect system that will satisfy both waveform quality and
timing requirements (accounting for both PCB routing mismatch and PCB SI degradation). Variation from these
recommendations may also work, but should be confirmed with PCB signal integrity analysis or lab
measurements.

8.4 Device Functional Modes
DLPC343x has two functional modes (ON/OFF) controlled by a single pin PROJ_ON:
• When pin PROJ_ON is set high, the projector automatically powers up and an image is projected from the
DMD.
• When pin PROJ_ON is set low, the projector automatically powers down and only microwatts of power are
consumed.

9 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.
9.1 Application Information
The DLPC343x controller requires to be coupled with DLP2010 DMD to provide a reliable display solution for
many data and video display applications. The DMDs are spatial light modulators which 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 DLPC343x. Applications of interest include projection embedded in display devices like smart
phones, tablets, cameras, and camcorders. Other applications include wearable (near-eye) displays, battery
powered mobile accessory, interactive display, low latency gaming display, and digital signage.

DLPS038B – JULY 2014 – REVISED FEBRUARY 2016
Typical Application (continued)
9.2.1 Design Requirements
A Pico projector is created by using a DLP chipset comprised of DLP2010 (.2 WVGA) DMD, DLPC343x
controller and DLPA2000 PMIC/LED driver. The DLPC343x does the digital image processing, the DLPA2000
provides the needed analog functions for the projector, and DMD is the display device for producing the
projected image.
In addition to the three DLP chips in the chipset, other chips may be needed. At a minimum a flash part is
needed to store the software and firmware to control the DLPC343x.
The illumination light that is applied to the DMD is typically from red, green, and blue LEDs. These are often
contained in three separate packages, but sometimes more than one color of LED die may be in the same
package to reduce the overall size of the pico-projector.
For connecting the DLPC343x to the host processing for receiving images, parallel interface is used. I2C should
be connected to the host processor for sending commands to the DLPC3430.
The only power supplies needed external to the projector are the battery (SYSPWR) and a regulated 1.8-V
supply.
The entire pico-projector can be turned on and off by using a single signal called PROJ_ON. When PROJ_ON is
high, the projector turns on and begins displaying images. When PROJ_ON is set low, the projector turns off and
draws just microamps of current on SYSPWR. When PROJ_ON is set low, the 1.8V supply can continue to be
left at 1.8 V and used by other non-projector sections of the product. If PROJ_ON is low, the DLPA2000 will not
draw current on the 1.8-V supply.
9.2.2 Detailed Design Procedure
For connecting together the DLP2010 (.2 WVGA) DMD, DLPC343x controller and DLPA2000 PMIC/LED Driver
see the reference design schematic. When a circuit board layout is created from this schematic a very small
circuit board is possible. An example small board layout is included in the reference design data base. Follow the
layout guidelines to achieve a reliable projector.
The optical engine that has the LED packages and the DMD mounted to it is typically supplied by an optical
OEM who specializes in designing optics for DLP projectors.
9.2.3 Application Curve
As the LED currents that are driven time-sequentially through the red, green, and blue LEDs are increased, the
brightness of the projector increases. This increase is somewhat non-linear, and the curve for typical white
screen lumens changes with LED currents is shown in Figure 21. For the LED currents shown, it is assumed that
the same current amplitude is applied to the red, green, and blue LEDs.

10 Power Supply Recommendations
10.1 System Power-Up and Power-Down Sequence
Although the DLPC343x requires an array of power supply voltages, (for example, VDD, VDDLP12,
VDD_PLLM/D, VCC18, VCC_FLSH, VCC_INTF), if VDDLP12 is tied to the 1.1-V VDD supply (which is assumed
to be the typical configuration), then there are no restrictions regarding the relative order of power supply
sequencing to avoid damaging the DLPC343x. (This is true for both power-up and power-down scenarios).
Similarly, there is no minimum time between powering-up or powering-down the different supplies if VDDLP12 is
tied to the 1.1-V VDD supply.
If however VDDLP12 is not tied to the VDD supply, then VDDLP12 must be powered-on after the VDD supply is
powered-on, and powered-off before the VDD supply is powered-off. In addition, if VDDLP12 is not tied to VDD,
then VDDLP12 and VDD supplies should be powered on or powered off within 100 ms of each other.
Although there is no risk of damaging the DLPC343x if the above power sequencing rules are followed, the
following additional power sequencing recommendations must be considered to ensure proper system operation.
• To ensure that DLPC343x output signal states behave as expected, all DLPC343x I/O supplies should remain
applied while VDD core power is applied. If VDD core power is removed while the I/O supply (VCC_INTF) is
applied, then the output signal state associated with the inactive I/O supply will go to a high impedance state.
• Additional power sequencing rules may exist for devices that share the supplies with the DLPC343x, and thus
these devices may force additional system power sequencing requirements.
Note that when VDD core power is applied, but I/O power is not applied, additional leakage current may be
drawn. This added leakage does not affect normal DLPC343x operation or reliability.
Figure 22 and Figure 23 show the DLPC343x power-up and power-down sequence for both the normal PARK
and fast PARK operations of the DLPC343x ASIC.

It is assumed that an external power monitor will hold the DLPC343x in system reset during power-up. It must do
this by driving RESETZ to a logic low state. It should continue to assert system reset until all ASIC voltages have
reached minimum specified voltage levels, PARKZ is asserted high, and input clocks are stable. During this time,
most ASIC outputs will be driven to an inactive state and all bidirectional signals will be configured as inputs to
avoid contention. ASIC outputs that are not driven to an inactive state are tri-stated. These include LED_SEL_0,
LED_SEL_1, SPICLK, SPIDOUT, and SPICSZ0 (see RESETZ pin description for full signal descriptions in Pin
Configuration and Functions. After power is stable and the PLL_REFCLK_I clock input to the DLPC343x is
stable, then RESETZ should be deactivated (set to a logic high). The DLPC343x then performs a power-up
initialization routine that first locks its PLL followed by loading self configuration data from the external flash.
Upon release of RESETZ all DLPC343x I/Os will become active. Immediately following the release of RESETZ,
the HOST_IRQ signal will be driven high to indicate that the auto initialization routine is in progress. However,
since a pullup resistor is connected to signal HOST_IRQ, this signal will have already gone high before the
DLPC343x actively drives it high. Upon completion of the auto-initialization routine, the DLPC343x will drive
HOST_IRQ low to indicate the initialization done state of the DLPC343x has been reached.
Note that the host processor can start sending I2C commands after HOST_IRQ goes low.
10.3 DMD Fast PARK Control (PARKZ)
The PARKZ signal is defined to be an early warning signal that should alert the ASIC 40 µs before DC supply
voltages have dropped below specifications in fast PARK operation. This allows the ASIC time to park the DMD,
ensuring the integrity of future operation. Note that the reference clock should continue to run and RESETZ
should remain deactivated for at least 40 µs after PARKZ has been deactivated (set to a logic low) to allow the
park operation to complete.
10.4 Hot Plug Usage
The DLPC343x provides fail-safe I/O on all host interface signals (signals powered by VCC_INTF). This allows
these inputs to be driven high even when no I/O power is applied. Under this condition, the DLPC343x will not
load the input signal nor draw excessive current that could degrade ASIC reliability. For example, the I2C bus
from the host to other components would not be affected by powering off VCC_INTF to the DLPC343x. TI
recommends weak pullups or pulldowns on signals feeding back to the host to avoid floating inputs.
If the I/O supply (VCC_INTF) is powered off, but the core supply (VDD) is powered on, then the corresponding
input buffer may experience added leakage current, but this does not damage the DLPC343x.
10.5 Maximum Signal Transition Time
Unless otherwise noted, 10 ns is the maximum recommended 20% to 80% rise or fall time to avoid input buffer
oscillation. This applies to all DLPC343x input signals. However, the PARKZ input signal includes an additional
small digital filter that ignores any input buffer transitions caused by a slower rise or fall time for up to 150 ns.

11 Layout
11.1 Layout Guidelines
11.1.1 PCB Layout Guidelines for Internal ASIC PLL Power
The following guidelines are recommended to achieve desired ASIC performance relative to the internal PLL.
The DLPC343x contains 2 internal PLLs which have dedicated analog supplies (VDD_PLLM , VSS_PLLM,
VDD_PLLD, VSS_PLLD). As a minimum, VDD_PLLx power and VSS_PLLx ground pins should be isolated using
a simple passive filter consisting of two series Ferrites and two shunt capacitors (to widen the spectrum of noise
absorption). It’s recommended that one capacitor be a 0.1-µF capacitor and the other be a 0.01-µF capacitor. All
four components should be placed as close to the ASIC as possible but it’s especially important to keep the
leads of the high frequency capacitors as short as possible. Note that both capacitors should be connected
across VDD_PLLM and VSS_PLLM / VDD_PLLD and VSS_PLLD respectfully on the ASIC side of the Ferrites.
For the ferrite beads used, their respective characteristics should be as follows:
• DC resistance less than 0.40 Ω
• Impedance at 10 MHz equal to or greater than 180 Ω
• Impedance at 100 MHz equal to or greater than 600 Ω
The PCB layout is critical to PLL performance. It is vital that the quiet ground and power are treated like analog
signals. Therefore, VDD_PLLM and VDD_PLLD must be a single trace from the DLPC343x to both capacitors
and then through the series ferrites to the power source. The power and ground traces should be as short as
possible, parallel to each other, and as close as possible to each other.

11.1.2 DLPC343x Reference Clock
The DLPC343x requires an external reference clock to feed its internal PLL. A crystal or oscillator can supply this
reference. For flexibility, the DLPC343x accepts either of two reference clock frequencies (see Table 10), but
both must have a maximum frequency variation of ±200 ppm (including aging, temperature, and trim component
variation). When a crystal is used, several discrete components are also required as shown in Figure 25.

11.1.3 General PCB Recommendations
TI recommends 1-oz. copper planes in the PCB design to achieve needed thermal connectivity.
11.1.4 General Handling Guidelines for Unused CMOS-Type Pins
To avoid potentially damaging current caused by floating CMOS input-only pins, TI recommends that unused
ASIC input pins be tied through a pullup resistor to its associated power supply or a pulldown to ground. For
ASIC inputs with an internal pullup or pulldown resistors, it is unnecessary to add an external pullup or pulldown
unless specifically recommended. Note that internal pullup and pulldown resistors are weak and should not be
expected to drive the external line. The DLPC343x implements very few internal resistors and these are noted in
the pin list. When external pullup or pulldown resistors are needed for pins that have built-in weak pullups or
pulldowns, use the value 8 kΩ (max).
Unused output-only pins should never be tied directly to power or ground, but can be left open.
When possible, TI recommends that unused bidirectional I/O pins be configured to their output state such that
the pin can be left open. If this control is not available and the pins may become an input, then they should be
pulled-up (or pulled-down) using an appropriate, dedicated resistor.

Max signal routing length includes escape routing.
Multi-board DMD routing length is more restricted due to the impact of the connector.
Due to board variations, these are impossible to define. Any board designs should SPICE simulate with the ASIC IBIS models to ensure
single routing lengths do not exceed requirements.

These values apply to PCB routing only. They do not include any internal package routing mismatch associated with the DLPC343x, the
DMD.
DMD HS data lines are differential, thus these specifications are pair-to-pair.
Training is applied to DMD HS data lines, so defined matching requirements are slightly relaxed.
DMD LS signals are single ended.
Mismatch variance applies to high-speed data pairs. For all high-speed data pairs, the maximum mismatch between pairs should be 1
mm or less.
11.1.6 Number of Layer Changes
• Single-ended signals: Minimize the number of layer changes
• Differential signals: Individual differential pairs can be routed on different layers, but the signals of a given pair
should not change layers.
11.1.7 Stubs
• Stubs should be avoided
11.1.8 Terminations
• No external termination resistors are required on DMD_HS differential signals.
• The DMD_LS_CLK and DMD_LS_WDATA signal paths should include a 43-Ω series termination resistor
located as close as possible to the corresponding ASIC pins.
• The DMD_LS_RDATA signal path should include a 43-Ω series termination resistor located as close as
possible to the corresponding DMD pin.
• DMD_DEN_ARSTZ does not require a series resistor.
11.1.9 Routing Vias
• The number of vias on DMD_HS signals should be minimized and should not exceed two.
• Any and all vias on DMD_HS signals should be located as close to the ASIC as possible.
• The number of vias on the DMD_LS_CLK and DMD_LS_WDATA signals should be minimized and not
exceed two.
• Any and all vias on the DMD_LS_CLK and DMD_LS_WDATA signals should be located as close to the ASIC
as possible.

DLPS038B – JULY 2014 – REVISED FEBRUARY 2016
11.1.10 Thermal Considerations
The underlying thermal limitation for the DLPC343x is that the maximum operating junction temperature (TJ) not
be exceeded (this is defined in the Recommended Operating Conditions). This temperature is dependent on
operating ambient temperature, airflow, PCB design (including the component layout density and the amount of
copper used), power dissipation of the DLPC343x, and power dissipation of surrounding components. The
DLPC343x’s package is designed primarily to extract heat through the power and ground planes of the PCB.
Thus, copper content and airflow over the PCB are important factors.
The recommended maximum operating ambient temperature (TA) is provided primarily as a design target and is
based on maximum DLPC343x power dissipation and RθJA at 0 m/s of forced airflow, where RθJA is the thermal
resistance of the package as measured using a glater test PCB with two, 1-oz power planes. This JEDEC test
PCB is not necessarily representative of the DLPC343x PCB; the reported thermal resistance may not be
accurate in the actual product application. Although the actual thermal resistance may be different, it is the best
information available during the design phase to estimate thermal performance. However, after the PCB is
designed and the product is built, TI highly recommended that thermal performance be measured and validated.
To do this, measure the top center case temperature under the worse case product scenario (max power
dissipation, max voltage, max ambient temperature) and validated not to exceed the maximum recommended
case temperature (TC). This specification is based on the measured φJT for the DLPC343x package and provides
a relatively accurate correlation to junction temperature. Take care when measuring this case temperature to
prevent accidental cooling of the package surface. TI recommends a small (approximately 40 gauge)
thermocouple. The bead and thermocouple wire should contact the top of the package and be covered with a
minimal amount of thermally conductive epoxy. The wires should be routed closely along the package and the
board surface to avoid cooling the bead through the wires.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
