Thank you for contacting Intel Community. Please be noted that Intel FPGA requires details information for failure analysis request. Please help to answer questions below in order for us to better understand your position. 1. Please provide full device details. 1.1. Device name: 1.2. Full part number: 2. What is the failure rate? What is the failure rate vs. tested sample? Example: 2 out of 100 units. 3. What is the failure symptom? Please elaborate the failure symptom in detail. 4. When did the failure happen? How did you discover the failure? 5. How did you determine the failure? Please elaborate the procedures. 6. Does the failure unit ever working before failure? 7. Did they violate solder re-flow temperature profiles, moisture sensitivity? 8. Did you swap the failure device to a known good board? Is the failure following the device or board? Regards, Wani

Hi, Refer below: 1. Please provide full device details. 1.1. Device name: IC 1.695M-bit EEPROM CMOS 20-PLCC 1.2. Full part number: AE1818-7675LF 2. What is the failure rate? What is the failure rate vs. tested sample? Example: 2 out of 100 units. - 7 / 246 3. What is the failure symptom? Please elaborate the failure symptom in detail. - Test program aborted due to E8251-60666 failed at Store Module Eeprom. [cid:image006.jpg@01D4E0C7.8E40C470][cid:image007.jpg@01D4E0C7.8E40C470] 4. When did the failure happen? How did you discover the failure? - The failure happen while perform Download Firmware. - The test program shown E8251-60666 “Eeprom header read from UUT does NOT match header written to UUT. 5. How did you determine the failure? Please elaborate the procedures. - Refer to the schematic, U101 is the configuration Eeprom. - We have perform measurement VOLTAGE for U101, good vs bad. [cid:image010.jpg@01D4E0C7.8E40C470] U101 Measurement Voltage (V) No U101 GOOD BAD 1 Pin 1 3.35v 3.30v 2 Pin 2 3.38v 3.30v 3 Pin 3 0 0 4 Pin 4 0 0 5 Pin 5 3.26v 3.30v 6 Pin 6 0 0 7 Pin 7 0 0 8 Pin 8 3.30v 0.035v 9 Pin 9 3.30v 0.035v 10 Pin 10 0 0 11 Pin 11 2.8v 2.79v 12 Pin 12 3.26v 3.30v 13 Pin 13 3.30v 3.30v 14 Pin 14 3.30v 3.30v 15 Pin 15 0 0 16 Pin 16 0 0 17 Pin 17 0 0 18 Pin 18 3.30v 3.30v 19 Pin 19 3.30v 3.30v 20 Pin 20 3.30v 3.30v 6. Does the failure unit ever working before failure? No 7. Did they violate solder re-flow temperature profiles, moisture sensitivity? No 8. Did you swap the failure device to a known good board? Is the failure following the device or board? We have done swapping experiment, the failure is following device. Thank you. Regards, Nabilah
