Let me address each of your questions in turn. 1. Warranty Confirmation — Direct Purchase from TI Since you have confirmed that PO# 9431033 was a direct purchase from TI (not through a third-party distributor), the parts are within TI's warranty coverage scope. You should submit a formal quality/warranty claim through TI Customer Support, referencing: PO# 9431033 MPN: TMS320F28335PGFA Lot/Date Codes: DC 202141 and DC 202240 The photos and your internal evaluation findings TI's quality team will make the final warranty disposition on a case-by-case basis after reviewing the submitted evidence. 2. Shelf Life and Manufacturing Expiry Date Per TI's official QRP data for the TMS320F28335PGFA: MSL Rating: Level 3 — 260°C / 168 hours (J-STD-020) Floor Life (once dry-pack is opened): 168 hours (7 days) at ≤30°C / ≤60% RH Regarding dry-pack shelf life (unopened sealed bag), the industry standard per J-STD-033 is 12 months from the bag seal date when stored at ≤40°C / ≤90% RH. TI does not publish a separate "manufacturing expiry date" — the shelf life clock runs from the bag seal date printed on the moisture barrier bag label. For your specific lots: DC 202141 = Week 41 of 2021 (approximately October 2021) DC 202240 = Week 40 of 2022 (approximately October 2022) If these parts were received in 2022 and the bags have remained sealed and properly stored, the shelf life of the earlier lot (DC 202141) may have already exceeded the 12-month guideline by the time of receipt or shortly thereafter. This is a point TI's quality team will likely scrutinize closely. Please check the bag seal date printed on the moisture barrier bag itself , as that is the controlling date — not the date code on the device. Important: You have confirmed only 4.5 hours of floor life exposure, which is well within the 168-hour limit. However, if the bags were stored for an extended period beyond 12 months before opening, a bake-out per J-STD-033 (125°C / 24 hours for MSL 3) would be the standard remediation before assembly. Whether TI considers this a warranty condition or a handling/storage issue will depend on the bag seal date. 3. Rescreening and Retaping — Impact on RMA This is an important question. Proceeding with rescreening and retaping before receiving TI's disposition on the quality case carries risk: Rescreening (electrical testing to separate passing from failing units) is generally acceptable as a characterization step and can strengthen your quality submission by providing data on electrical functionality. Retaping/repackaging of units that have already been identified as potentially defective could complicate TI's ability to inspect the parts in their original condition, which may negatively impact your RMA consideration. Recommendation: Before proceeding with any rescreening or retaping, notify TI Customer Support and request explicit written guidance. TI's quality team may want to inspect parts in their as-received condition, or they may authorize rescreening as part of the investigation. Acting without authorization could be interpreted as altering the evidence and may jeopardize the RMA outcome. In your quality case submission, clearly state your intent to conduct rescreening and ask for TI's approval before proceeding. Summary of Next Steps Action Priority Check bag seal date on moisture barrier bag Immediate Submit formal quality case to TI Customer Support with invoice, photos, lot/DC info Immediate Request written authorization from TI before rescreening/retaping Before proceeding Continue internal electrical/mechanical evaluation and document results Ongoing Best Regards, Zackary Fleenorhttps://e2e.ti.com/support/site-support-group/site-support/f/site-support-forum/1656044/launchxl2-tms57012-tms570ls12x-launchpad-development-kit-is-not-working/6388557Fri, 19 Jun 2026 04:24:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:ba4002f7-eaa7-499a-9342-a25d4c97eb14jagadish gundavarapuHi, Recommended Troubleshooting Steps: Power Supply Verification: Try a different USB cable and USB port Use a USB port that can provide adequate current (avoid USB hubs) Check if the USB cable supports both data and power (some cables are power-only) Hardware Inspection: Examine the board for any signs of component damage, especially around power regulation circuits Check for loose connections or cold solder joints Look for any burnt components or discoloration Power Rail Testing: If you have a multimeter, check the voltage levels on the main power rails The dim LED6 suggests partial power delivery but insufficient current Reset and Recovery: Try holding any reset buttons while connecting power Look for jumper settings that might affect power or boot mode Check if there are any DIP switches that control power or debug modes Alternative Power Sources: If the board supports external power input, try using an external power supply Some boards have power selection jumpers between USB and external power Likely Causes: Power regulation circuit failure (voltage regulator or associated components) USB power management IC failure Short circuit on one of the power rails causing current limiting -- Thanks & regards, Jagadish.https://e2e.ti.com/support/site-support-group/site-support/f/site-support-forum/1653587/tms320f28335-component-surface-bulging/6388535Fri, 19 Jun 2026 03:33:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:0d80cfaf-c188-42bb-96cb-eaa63f26d47bFatin NadzirahTo confirm the affected lot, please advise if we can proceed with rescreening and retaping?

Currently, when the board is connected to power via USB, the only sign of life is that LED6 is on, but it is very dim. All other on-board LEDs remain completely off, and the board is completely unrecognizable by Code Composer Studio and the XDS110 debugger. Here are my order details for your reference:LAUNCHXL2-TMS57012https://e2e.ti.com/support/site-support-group/site-support/f/site-support-forum/1655045/pspice-for-ti-aceess-keyFri, 12 Jun 2026 16:25:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:8f3b889b-e528-4c44-95e0-57e6f856526bPeter LichardPart Number: PSPICE-FOR-TI Hello, I have got a new computer on which I'd like to install PSPICE-for-TI.

Thank you PeterPSPICE-FOR-TIhttps://e2e.ti.com/support/site-support-group/site-support/f/site-support-forum/1653587/tms320f28335-component-surface-bulging/6376600Tue, 09 Jun 2026 23:03:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:6bcca9b8-f9fc-4430-9cc8-575d891447baFleenorHi Fatin, Thank you for the detailed submission and photos. Bulging Condition — Acceptability TI's published documentation does not define specific acceptance criteria for mold compound surface bulging, so I cannot confirm from documentation alone whether the condition observed is within manufacturing tolerances or constitutes a defect. That determination requires a formal quality review by TI's product quality team on a case-by-case basis. Reliability Standing The TMS320F28335PGFA is an active, catalog-rated product assembled at TI Philippines in a 176-pin LQFP package. It has passed all standard JEDEC reliability qualifications: Stress Test Condition Result HTOL 125C, 1000 hours Pass HTSL 150C, 1000 hours Pass Biased HAST 130C / 85% RH, 96 hours Pass Unbiased HAST 130C / 85% RH, 96 hours Pass Temperature Cycle -65 / 150C, 500 cycles Pass MTBF is rated at 441.6 million hours at 55C with zero failures across 5,225 samples. However, none of this qualification data speaks to surface bulging as a physical appearance criterion — the two are evaluated separately. Potential Root Cause — Moisture Sensitivity This is worth flagging before escalating to the TI Quality and Reliability team. The TMS320F28335PGFA is rated MSL Level 3, meaning once the moisture barrier bag is opened, parts must be assembled within 168 hours under controlled floor conditions (30C / 60% RH or better). If parts were stored outside the bag beyond that window without baking, moisture absorption into the mold compound is a credible and consistent explanation for the bulging pattern observed across multiple unused units from the same lot. Before submitting a quality case to TI, please confirm the following: Whether the dry-pack seal was intact upon receipt Storage conditions and duration after the bag was opened Whether all affected units share the same lot and date code This context will be critical for TI's quality team in determining whether the condition originated at manufacturing or during downstream handling and storage, and it will directly affect the outcome of any warranty or RMA consideration. Warranty Coverage TI warranty coverage applies only to products purchased directly from TI or through their authorized distribution network — Arrow Electronics, Digi-Key Electronics, or Mouser Electronics. Products sourced outside of those channels are not eligible for warranty support. Please confirm that PO# 9431033 was fulfilled through one of those authorized channels prior to escalating. If it was not, TI will not be in a position to support a warranty or RMA claim. Note also that per TI's standard terms, no refund is available on purchased parts, though a formal RMA may be considered depending on the outcome of TI's quality review. Recommended Next Steps Verify the purchase channel against TI's authorized distributor list Confirm dry-pack integrity, floor life exposure, and lot and date code for all affected units Submit a formal quality case to TI Customer Support with PO# 9431033, lot and date code, and the photos provided — this is the correct path for quality escalation and any potential RMA consideration Continue your internal electrical and mechanical evaluation and include those results as supporting evidence in the TI quality submission Best Regards, Zackary Fleenorhttps://e2e.ti.com/support/site-support-group/site-support/f/site-support-forum/1652905/amc1100evm-amc1100evm-sbau196a-does-not-have-schematic/6376564Tue, 09 Jun 2026 22:26:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:15e5c9f8-f8e8-4341-b711-afa473988682Jeffrey VaselHi Alexander. Thank you for the schematic. I am working on an educational project based on "800VA Pure Sine Wave Inverter slaa602a" which uses the AMC1100. So I do not have strict design requirements. Also, I plan on experimenting with the AMC1100 for some energy monitoring as well. Thx.

The schematic is the same as the AMC1200 version of the EVM, it is simply a variant. May I ask about your interest in the AMC1100? This is a fairly old device at this point and we've made several advances in both analog performance and isolation technology.

We only encountered this problem in 2 of them. The chip was working properly, we had tested it, but then for some reason it stopped working. They removed the chip and threw it away, so we can't take any measurements, unfortunately. We repaired it and installed a new chip, and it is working without any problems now. Do you have any idea what might have caused this? Best Regards.
