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 DLPA200x PMIC chip, the DLPC343x takes much longer than 40 µs to park the mirrors. The DLPA200x 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 DLPA200x monitors power to the DLPC343x and detects an eminent power loss condition and drives the PARKZ signal accordingly. Reserved P12 I6 TI internal use. Should be left unconnected.

Reserved M13 I6 TI internal use. Should be left unconnected. Reserved N11 I6 TI internal use. Should be left unconnected. Reserved P11 I6 TI internal use 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. RESETZ TSTPT_0 N12 C11 R12 B1 Test pin 0 (includes weak internal pulldown) – tri-stated while RESETZ is asserted low. Sampled as an input test mode selection control approximately 1.5 µs after de-assertion of RESETZ, and then driven as an output. Normal use: reserved for test output. Should be left open or unconnected for normal use. Note: An external pullup should not be applied to this pin to avoid putting the DLPC343x in a test mode. Without external pullup Feeds TMSEL(0) (1) (2) (3) 6 (2) With external pullup (3) Feeds TMSEL(0) 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.

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. HOST_IRQ (2) N8 IIC0_SCL N10 B7 I2C slave (port 0) SCL (bidirectional, open-drain signal with input hysteresis): An external pullup is required. The slave I2C I/Os are 3.6-V tolerant (high-volt-input tolerant) and are powered by VCC_INTF (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). Reserved R11 B8 TI internal use. TI recommends an external pullup resistor. IIC0_SDA N9 B7 I2C slave (port 0) SDA. (bidirectional, open-drain signal with input hysteresis): An external pullup is required. The slave I2C port is the control port of ASIC. The slave I2C I/Os are 3.6-V tolerant (high-voltinput tolerant) and are powered by VCC_INTF (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).

They will continue to be driven low throughout the auto-initialization process. A weak, external pulldown resistor is still recommended to ensure that the LEDs are disabled when I/O power is not applied.

DLPC343x hold capture timing has been set to facilitate reliable operation with standard external SPI protocol devices.

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 (with External Pullup) (INIT_BUSY) 3 µs min 0 ms 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. Figure 10.

DLPC343x is part of the chipset comprising DLPC343x controller, DLP3010 (.3 720) DMD, and DLPA200x PMIC/LED driver. All three components of the chipset must be used in conjunction with each other for reliable operation of the DLP3010 (.3 720) 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). 8.2 Functional Block Diagram Parallel Video / BT656 Port 5 24 Input Control Processing Test Pattern Generator Splash Screen Video Processing - Chroma Interpolation - Color Space Conversion - Brightness Enhancement - Dynamic Scaling - Keystone Correction - Gamma Correction eDRAM (Frame Memory) ARM Cortex M3 128KB I/D Memory 2 I C_0 SPI_0 SPI_1 I2C_1 LED Control Other options - Image Format Processing - Contrast Adjust - Color Correction - CAIC Processing - Blue Noise STM - Power Saving Operations DLPTM Display Formatting Real Time Control System DMD I/F 20 GPIO Clocks & Reset Generation DMD_HS_CLK (sub-LVDS) DMD_HS_DATA(A:H) (sub-LVDS) DMD_LS_CLK DMD_LS_WDATA DMD_LS_RDATA DMD_DEN_ARSTZ Clock (Crystal) Reset Control 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 6 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.

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 4 and Table 5. Table 4.

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 32 Submit Documentation Feedback Copyright © 2014–2016, Texas Instruments Incorporated Product Folder Links: DLPC3433 DLPC3438 DLPC3433, DLPC3438 www.ti.com • • • DLPS035B – FEBRUARY 2014 – REVISED JANUARY 2016 A read status register (RDSR) instruction (repeated as needed) to poll the write enable latch (WEL) bit After the write enable latch (WEL) bit is set, the program or erase instruction is executed Note the flash automatically clears the write enable status after each program and erase instruction The specific instruction OpCode and timing compatibility requirements are listed in Table 7 and Table 6.

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 7 contains a list of 1.8-, 2.5-, and 3.3-V compatible SPI serial flash devices supported by 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 DLPA200x. 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. 34 Submit Documentation Feedback Copyright © 2014–2016, Texas Instruments Incorporated Product Folder Links: DLPC3433 DLPC3438 DLPC3433, DLPC3438 www.ti.com DLPS035B – FEBRUARY 2014 – REVISED JANUARY 2016 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 17 and Figure 18 show an example of the application of CAIC for one color channel. Figure 17. Input Pixels Example Figure 18. Displayed Pixels After CAIC Processing Figure 18 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.

Thus, CAIC can achieve an overall LED power reduction while maintaining the same overall image brightness as if CAIC was not used. Figure 19 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 19. 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 20 shows a split screen example of the impact of the LABB algorithm for an image that includes dark areas. Figure 20. Boosting Brightness in Local Areas of an Image 36 Submit Documentation Feedback Copyright © 2014–2016, Texas Instruments Incorporated Product Folder Links: DLPC3433 DLPC3438 DLPC3433, DLPC3438 www.ti.com DLPS035B – FEBRUARY 2014 – REVISED JANUARY 2016 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 8 shows the four options available for the DLP3010 (.3 720p) DMD specifically. Table 8.

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).

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.

Software can reprogram the selection at any time. 8.3.11 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. DMD_HS Differential Signals DMD_LS Signals Figure 21.

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 is required to be coupled with DLP3010 DMD to provide a reliable display solution for various 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 accessory projectors, projectors embedded in display devices like notebooks, laptops, tablets, and hot spots. Other applications include wearable (near-eye or head mounted) displays, interactive display, low latency gaming display, and digital signage. 9.1.1 DLPC343x System Design Consideration 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. 9.2 Typical Application + Charger DC_IN BAT ± A common application when using DLPC343x controller with DLP3010 DMD and DLPA200x/DLPA3000 PMIC/LED driver is for creating an accessory Pico projector for a smartphone, tablets, or any other display source.

The DLPC343x does the digital image processing, the DLPA200x/DLPA3000 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 DLPC343x. 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 DLPA200x/DLPA3000 will not draw current on the 1.8-V supply. 9.2.2 Detailed Design Procedure For connecting together the DLP3010 (.3 720p) DMD, DLPC343x controller and DLPA200x/DLPA3000 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 22 when using the DLPA2005. For the LED currents shown, it is assumed that the same current amplitude is applied to the red, green, and blue LEDs.

(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 23 and Figure 24 show the DLPC343x power-up and power-down sequence for both the normal PARK and fast PARK operations of the DLPC343x ASIC.

DLPC343x Power-Up / PARKZ = 0 initiated Fast PARK and Power-Down 10.2 DLPC343x Power-Up Initialization Sequence 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.

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. 46 Submit Documentation Feedback Copyright © 2014–2016, Texas Instruments Incorporated Product Folder Links: DLPC3433 DLPC3438 DLPC3433, DLPC3438 www.ti.com DLPS035B – FEBRUARY 2014 – REVISED JANUARY 2016 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 0.1uf capacitor and the other be a 0.01uf 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.

A crystal or oscillator can supply this reference. For flexibility, the DLPC343x accepts either of two reference clock frequencies (see Table 11), 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 26. PLL_REFCLK_I PLL_REFCLK_O RFB RS Crystal C L1 C L2 A. CL = Crystal load capacitance (farads) B.

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.

Example Layout 11.3 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. 52 Submit Documentation Feedback Copyright © 2014–2016, Texas Instruments Incorporated Product Folder Links: DLPC3433 DLPC3438 DLPC3433, DLPC3438 www.ti.com DLPS035B – FEBRUARY 2014 – REVISED JANUARY 2016 12 Device and Documentation Support 12.1 Device Support 12.1.1 Third-Party Products Disclaimer TI'S PUBLICATION OF INFORMATION REGARDING THIRD-PARTY PRODUCTS OR SERVICES DOES NOT CONSTITUTE AN ENDORSEMENT REGARDING THE SUITABILITY OF SUCH PRODUCTS OR SERVICES OR A WARRANTY, REPRESENTATION OR ENDORSEMENT OF SUCH PRODUCTS OR SERVICES, EITHER ALONE OR IN COMBINATION WITH ANY TI PRODUCT OR SERVICE. 12.1.2 Device Nomenclature 12.1.2.1 Device Markings DLPC343x DLPC343xRXXX XXXXXXXXXX-TT LLLLLL.ZZZ PH YYWW 1 2 SC 3 4 5 Terminal A1 corner identifier Marking Definitions: Line 1: DLP® Device Name: DLPC343x = x indicates a 3 or 8 device name ID.

Active Pixels Per Line (APPL) Defines the number of pixel clocks in a line containing displayable data: APPL is a subset of the TPPL. Horizontal Back Porch (HBP) Blanking Number of blank pixel clocks after horizontal sync but before the first active pixel. Note: HBP times are reference to the leading (active) edge of the respective sync signal. Horizontal Front Porch (HFP) Blanking Number of blank pixel clocks after the last active pixel but before Horizontal Sync. Horizontal Sync (HS) Timing reference point that defines the start of each horizontal interval (line). The absolute reference point is defined by the active edge of the HS signal. The active edge (either rising or falling edge as defined by the source) is the reference from which all horizontal blanking parameters are measured. Total Lines Per Frame (TLPF) Defines the vertical period (or frame time) in lines: TLPF = Total number of lines per frame (active and inactive). Total Pixel Per Line (TPPL) Defines the horizontal line period in pixel clocks: TPPL = Total number of pixel clocks per line (active and inactive). Vertical Sync (VS) Timing reference point that defines the start of the vertical interval (frame). The absolute reference point is defined by the active edge of the VS signal. The active edge (either rising or falling edge as defined by the source) is the reference from which all vertical blanking parameters are measured. Vertical Back Porch (VBP) Blanking Number of blank lines after vertical sync but before the first active line.

TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device.
