DLPC964: Inquiry regarding issues with a custom board using the DLPC964

JH Shin — Fri, 16 Oct 2026 08:16:40 GMT

Part Number: DLPC964

Hello,

My customer has a few questions regarding the use of the DLPC964.

Q1. I understand that there are firmware versions 1.0, 1.1, and 2.0 for the DLPC964, and that the choice depends on the FPGA being used. Is this correct?

Q2. Should I use Version 1.0 when working with the XC7VX415T?

Q3. For Version 1.0, only the .MCS file is available. Could you please provide the .bit file as well?

Q4. I have designed a custom board using the same circuitry as the EVM and successfully completed the flash download (verified via the readback feature in Vivado). However, the 'DONE' and 'heartbeat' signals on the DLPC964 IC are not active. Even though I have loaded the firmware intended for the EVM, the board is not functioning correctly. Could you please provide some advice on how to proceed with debugging this issue?

Q5. If the flash memory recommended by TI is unavailable, are there alternative flash products that can be used instead? If so, please provide a complete list of suitable alternatives.

Thank you.

Hello, thank you for your prompt response.

I believe there may have been some misunderstandings, so I would like to clarify a few points and ask some follow-up questions.

We are not using a separate XC7VX415T FPGA. We are using the DLPC964 controller purchased directly from TI.
The link you referenced (DLPLCRC964EVM-SW) appears to provide the GUI and software tools for the DLPC964, which is not what we are asking about. We are looking for the MCS or BIN file that needs to be programmed into the Flash memory to boot the DLPC964. We obtained the file from the following link: DLPR964-FW v1.1. Could you please confirm whether this is the correct firmware package for this purpose?
Our issue is that the DONE_ signal is not being asserted. To clarify the required startup conditions, is it correct that DONE_ should assert when SYS_CLK100 and DMD_GTREFCLK are supplied, even while the system remains in the reset state? Or are there other prerequisites for DONE_ to assert?
Regarding Flash compatibility, my understanding is that TI only guarantees operation with the S25FL256SAGMFI011, and that compatibility with other Flash devices cannot be guaranteed. Is this correct?
The INIT_B signal goes High and remains High for approximately 2 ms before going Low again, even though PROGRAM_B stays High throughout the entire process.

The Flash read and write operations appear to be functioning normally. I also read back the Flash contents and verified that the readback data matches the original MCS file exactly. However, the DONE signal is still not asserted.

Thank you for your help and clarification.

Hello JH,

Please see my response in blue below regarding the the customers DLPC964 questions.

Q1. I understand that there are firmware versions 1.0, 1.1, and 2.0 for the DLPC964, and that the choice depends on the FPGA being used. Is this correct?

Firmware versions 1.0, 1.1, and 2.0 (DLPC964-APPS-FPGA-FW) are for the front-ends Apps FPGA (ZCU102), not for the DLPC964 FPGA. TI's DLPC964 firmware is located here (DLPLCRC964EVM-SW) and are v1.0, v1.1, and v1.2.

However, please be aware that TI's DLPC964 firmware is encrypted and only runs on the security‑enabled DLPC964ZUM controller. A standard off‑the-shelf XC7VX415T cannot boot it, even on EVM-matching hardware.

The E2E forums here will explain this more in-depth -> https://e2e.ti.com/support/dlp-products-group/dlp/f/dlp-products-forum/1640904/dlpc964-i-fused-dplc964-fw-xc7vx415t-2ffg1158c-of-the-board-we-are-developing-but-there-is-no-done-signal

Q2. Should I use Version 1.0 when working with the XC7VX415T?

Same answer as Q1 above!

Q3. For Version 1.0, only the .MCS file is available. Could you please provide the .bit file as well?

Same answer as Q1 above! If you would still like me to provide the bit file, I can! Send me a friend request via E2E forum and send me a private message! I will send you the .bit file though E2E private message.

Make sure DONE_) is asserted before INIT_DONE. DONE_0 must assert before INIT_DONE! Successful flash programming alone doesn't confirm boot. If DONE_0 is high but INIT_DONE stays low, verify stable SYS_CLK100 (100 MHz) and DMD_GTREFCLK (112.5 MHz) before SYS_ARSTZ release, confirm power-rail sequencing, and check the Aurora/DMD link (HSSI_BUS_ERR).

Another great E2E reference for review -> https://e2e.ti.com/support/dlp-products-group/dlp/f/dlp-products-forum/1677158/dlpc964-dlpc964-init_done-is-always-0

Q5. If the flash memory recommended by TI is unavailable, are there alternative flash products that can be used instead? If so, please provide a complete list of suitable alternatives.

The validated flash we use is the S25FL256SAGMFI011 (Vivado device S25FL256Sxxxx1). S25FS256SAGNFI000 is a non-supported early-development option that can cause boot failure. No other specific alternate part numbers are available in current findings.

DLPC900: DLPC900 video mode latency

Arik Pel — Wed, 14 Oct 2026 08:44:16 GMT

Part Number: DLPC900

When working in duel mode using the DLPC900 video mode, HDMI input, What is the video latency?

Is there any option to bypass the internal prosses to reduce the latency ?

Thanks

Arik

RE: DLPC900: DLPC900 video mode latency

Aaron Black — Thu, 15 Oct 2026 22:26:16 GMT

Hello Arik,

Could you please advise what version of firmware you have programmed here?

If you utilize a photodiode and look at the output of a white screen, you should be able to see how this is composed as you display red, blue, and green independently. Please keep in mind that this is 8-bit grayscale this means it's 3x (red, green, blue) at 8-bit totaling to a 24-bit frame.

I cannot directly say what that timing should be as this changes. The transition time for our DMDs is around 8us but that can change as well.

Best,

Aaron

DLPDLCR3010EVM-G2: DLP LightCrafter Display 3010 EVM shuts down immediately after startup

Art Mecina — Thu, 24 Sep 2026 19:19:22 GMT

Part Number: DLPDLCR3010EVM-G2

Hi Team,

Appreciate your help on our customer who are having issues with DLPDLCR3010EVM-G2 Please see below in verbatim.

"Customer File.zip I am having a startup issue with a DLP LightCrafter Display 3010 EVM (DLPDLCR3010EVM).

When I power on the unit, LEDs D2 and D3 are initially on. Then D4 turns on for approximately one second and the projector displays an image. After about one second, the projected image turns off, D4 turns off, and only D2 and D3 remain on.

The same behavior occurs whether the external display/video connection is connected or disconnected, so it does not appear to depend on the video source. The fan continues running. Power cycling the unit previously allowed it to operate normally temporarily, but the problem has returned.

Could you please help me determine what the D2, D3, and D4 LED sequence indicates and what could cause the projector to shut down approximately one second after startup? Please also let me know what measurements or diagnostic steps I should perform to identify the faulty component."

Thanks in advance,

Art

Kevin Rivera — Thu, 15 Oct 2026 15:43:00 GMT

Hello Alice,

Could you measure the following highlighted lines during bootup? If these three could be measured alongside HOST_IRQ this could help point to the potential issue.

Could you also confirm that the properly rated power supply is being used?

Additionally, the power going to the DMD would be good to capture, since proj_on is going low I do not suspect the issue is here, but it would be good to check.

Thank you!

RE: DLPC900: DLPC900 video mode latency

Arik Pel — Thu, 15 Oct 2026 13:16:05 GMT

Thanks for the replay, Aaron

One additional question:

Currently working in Video mode with the DLP9000 DMD using 2 DLPC900, 8 bits grayscale, operating at 60 frames per second and would like to obtain more detailed technical information regarding the micromirror timing characteristics.

Specifically, I am interested in understanding the timing constraints associated with mirror state transitions for the LSB and LSB +1, On & off timing:

What is the minimum micromirror switching or transition time specified for the DLP9000?
During 16.67 msec frame operation, what portion of the frame period is occupied by mirror transition and is the 8 bits has the right timing deviation? Meaning T/256, T/128 ….

Thank you for your assistance.

Part Number: DLPC900

Working with the DLP900 can I load a new Gamma correction table, and is there any application to build it?

RE: DLPC900: DLPC900 video mode latency

Aaron Black — Wed, 14 Oct 2026 21:07:10 GMT

Hello Arik,

Thank you for coming to E2E with your question!

The DLPC900 will always have a frame buffered. If you are using the dual EVM we provide, the HDMI input is limited to 30Hz input. At this rate a frame will be at least 33.3us.

The controller is capable of more than that, but the concept is the same for having a frame of buffer.

Aaron

RE: DLP2010: Inquiry regarding replacements for DLP2010 and DLP3010

Aaron Black — Wed, 14 Oct 2026 20:46:54 GMT

Hello Grady,

We plan to have the 'LC' parts still be available for the next few years, likely 2030, at which time a LTB can be requested and stored parts can be utilized for years after.

If it is early into development and support is needed for a decade or further, I would advise to work with TI closer as we are developing alternates to this as a solution for these applications of Dental Scanning, 3D Print and Machine Vision. These parts will be available in the near future but no dates will be shared at this time.

RE: DLP2010: Inquiry regarding replacements for DLP2010 and DLP3010

Grady Lee — Tue, 13 Oct 2026 23:22:51 GMT

Hi, Aaron

Thank you for response.

So, the best course of action right now is to consider switching to the DLP2010LC and DLP3010LC, correct?

1) However, is it also true that there are plans for a "Last Time Buy" and EOL (End of Life) for the DLP2010LC and DLP3010LC within the next few years?
I noticed a comment you made in an E2E forum post stating, "Unfortunately, the DLP3010LC is also getting close to Last Time Buy status as well."

( DLP3010LC: DLP3010 replacement - DLP products forum - DLP®︎ products - TI E2E support forums )

2) And are you saying that the DLPC3470 or DLPC3478 controllers themselves are also slated for 'Last Time Buy' and 'EOL' within the next few years?

3) In that case, is there a DLP solution you would recommend for developing a new dental scanning product?

Please check. Thank you.

DLP5500: Optical Setup Issues

Sam Melvin — Tue, 13 Oct 2026 19:45:04 GMT

Part Number: DLP5500

Hi everyone,

We're setting up a DLP5500 for imaging into a microscopy system. The mirrors will be illuminated by a collimated laser beam and then imaged onto the imaging plane. The issue at the moment is that I can't wrap my head around where the incident light should be coming from in relation to the face of the DMD. Page 23 of the documentation states that incident light should be coming from the A-1 corner at an angle of 12 degrees from the parallel to the board. I've tried that and the image is not where it is supposed to be. The image in the documentation has not been of much assistance.

Does anyone have a diagram of their setup I could look at?

Our previous DMD was XY setup and easier to work with, IMHO.

Sam

RE: DLP2010: Inquiry regarding replacements for DLP2010 and DLP3010

Aaron Black — Tue, 13 Oct 2026 19:26:55 GMT

Hello Grady,

The DLP2010 and DLP3010 are indeed 'End of Life' status.

If customers are utilizing these devices for dental scanning solutions, the associated DLP2010LC and DLP3010LC should meet their needs as these parts are not yet going to EOL. They will require a replacement of the DLPC3430 or DLPC3438 to the DLPC3470 or DLPC3478.

Please note, if customers are looking to develop new products, we have to note that these devices and their associated controllers will be available until we also go to Last Time Buy and EOL for these devices in the next few years as well.

Best,

Aaron

DLP3940S-Q1: DLP3940S-Q1: Via Size

Jaewon Park — Mon, 12 Oct 2026 05:44:54 GMT

Part Number: DLP3940S-Q1

Hello,

I am designing a PCB for the DLP3940S-Q1 FSC package.

To route the signals from the LGA pads to the internal PCB layers,
we are considering placing vias directly inside the LGA PCB lands
using a via-in-pad structure.

Could you please confirm whether placing a via inside the LGA land
is acceptable for the DLP3940S-Q1 FSC package?

If via-in-pad is allowed, could you please provide TI’s recommended
dimensions for the following?

- Finished via-hole diameter
- Via pad diameter
- LGA PCB land size

My understanidng is that LGA PAD Size is 0.52 x 0.52 mm, so that there must be recommedation via-in pad size.

Please also let us know if there are any special requirements or potential concerns regarding the via-in-pad structure.

Thank you for your support.

Best regards,
Jaewon Park

RE: DLP3940S-Q1: DLP3940S-Q1: Via Size

Michael Ly — Tue, 13 Oct 2026 10:39:32 GMT

Hello Jaewon,

Our mechanical engineer has the following recommendations:

Vias in the DMD PCB pad area is common but can cause electrical interconnect issues if not done correctly.

If the PCB is a hard [rigid] PCB (not thin flex) then filled vias should be used to provide a smooth surface. It is still best to minimize the via size as the filled via is not perfect. The diameter is generally dictated by the PCB process and the thickness of the PCB. It is still best to locate the via as close to one of the corners as layout rules allow.

If the PCB is a thin flex then the filled via process is generally not available. In this case the via should be as small as the manufacturing process allows. Since the PCB is thinner than a hard pcb the process allows for a smaller diameter. It is best to locate the via as close to one of the corners as layout rules allow.

Below are slides that have been provided to customers previously for other DMDs.

Attached is one of our engineering revisions for a DMD board we've been using successfully for months:

e2e.ti.com/.../DLP120E2_5F00_fab.pdf

You will find that the DMDs on our rigid PCB has the following drill table from the file above. Please take a careful look at it before your implementation.

I can provide the layout file to you if you need further details. Please let me know!

Regards,
Michael Ly
