Definitions 12 RELIABILITY MONITOR -- ATMEL PROPRIETARY Reliability Monitor Report Date: Aug 20, 2010 Executive Summary The intent of the Reliability Monitor Program is to measure the reliability of previously qualified devices on a quarterly basis. This is achieved by selecting representative devices within a process, package or business unit and performing a series of reliability tests to ensure that the reliability has maintained over time. Listed below are the overall results for the last quarter. 1. High Temperature Operating Life (125° - 150°C; 0 failures) Failure Rate: 8 FITS (2,058K device-hours) Note: The Exponential Model is used to derive FIT rates (60% Confidence; EA = 0.6 eV). Also, Thermal and Voltage Acceleration are used to compute the overall acceleration factor. Weighted acceleration factors (WAF) for a group of products are calculated by taking the weighted average of each device’s acceleration factor multiplied by its corresponding device hours. All failures were inconclusive. 2. Data Retention Bake (150°C; 0 failures) Failure Rate: 15 FITS (539K device-hours) Note: The Exponential Model is used to derive FIT rates (60% Confidence; EA = 0.6 eV). Since there is no bias applied during testing and the stress temperature is fixed for all devices at 150°C, the acceleration factor is 117 for all groupings. 3. Temperature Cycle (-65°C to 150°C, 500 cycles) * Failure Rate: 0.00% (0 failures out of 205 units) 4. Temperature Humidity Bias (85°C/85%RH) and HAST (130°C/85%RH) * Failure Rate: 0.00% (0 failures out of 308K device-hours) Note: A 20:1 Acceleration Factor is used to combine HAST results with THB). 5. Steam Pressure Pot (121°C/100%RH) * Failure Rate: 0.00% (0 failures out of 240 units) RELIABILITY MONITOR -- ATMEL PROPRIETARY * indicates that preconditioning is performed prior to the stress test. 1 High Temperature Operating Life (sorted by FAMILY) BU QTR 48 Hours 168 Hours 500 Hours 1K Hours REJ SS REJ SS REJ SS REJ SS Device-Hours* WAF EFR PPM FITS APG 1 LAST 4Q 0 0 162 648 0 0 162 648 0 0 162 648 0 0 162 648 162,000 648,000 35 35 0 0 160 40 ASIC 1 LAST 4Q 0 0 145 6,756 0 0 145 1,779 0 0 145 1,779 0 0 100 1,520 122,500 1,888,396 19 17 0 0 392 28 MEMORY 1 LAST 4Q 0 0 900 3,400 0 0 500 1,800 0 0 500 1,796 0 0 500 1,787 519,200 1,868,972 48 52 0 0 37 9 MCU 1 LAST 4Q 0 0 2,534 8,224 0 0 462 1,413 0 0 462 1,413 0 0 462 1,259 561,456 1,662,928 3 14 0 0 525 38 RFA 1 LAST 4Q 0 0 693 2,847 0 0 693 2,847 0 0 693 2,847 0 0 693 2,693 693,000 3,153,000 117 119 0 0 11 2 ATMEL 1 LAST 4Q 0 0 4,434 21,875 0 0 1,962 8,487 0 0 1,962 8,483 0 0 1,917 7,907 2,058,156 9,221,296 56 60 0 0 8 2 RELIABILITY MONITOR -- ATMEL PROPRIETARY 2 High Temperature Operating Life (sorted by TECHNOLOGY) TECH QTR 48 Hours 168 Hours 500 Hours 1K Hours Device-Hours* WAF EFR PPM FITS 154 357,612 3 0 899 0 154 192,500 117 0 41 154 654 0 0 154 654 154,000 807,000 117 83 0 0 51 14 0 154 0 154 154,000 117 0 51 77 0 77 0 77 77,000 117 0 102 0 77 0 77 0 77 77,000 206 0 58 77 0 77 0 77 0 0 38,500 117 0 203 0 230 0 230 0 230 0 230 230,000 146 0 27 1 LAST 4Q 0 0 385 847 0 0 385 847 0 0 385 847 0 0 385 847 385,000 924,000 117 163 0 0 20 6 63K 1 LAST 4Q 0 0 600 1,500 0 0 200 500 0 0 200 496 0 0 200 487 219,200 540,172 48 69 0 0 88 25 58K 1 LAST 4Q 0 0 1,332 1,939 0 0 231 308 0 0 231 308 0 0 231 231 283,848 347,788 3 3 0 0 1,248 997 57K 1 LAST 4Q 0 385 0 385 0 385 0 385 385,000 19 0 128 1 LAST 4Q 0 0 80 320 0 0 80 320 0 0 80 320 0 0 80 320 80,000 320,000 48 48 0 0 237 59 REJ SS REJ SS REJ SS REJ SS 1 LAST 4Q 0 2,522 0 353 0 353 0 1 LAST 4Q 0 231 0 231 0 231 UHF 1 LAST 4Q 0 0 154 654 0 0 154 654 0 0 SCMOS3 1 LAST 4Q 0 154 0 154 1 LAST 4Q 0 77 0 1 LAST 4Q 0 77 LAST 4Q 0 1 LAST 4Q 75K Z92 UNI3 SIGE1 SIGE2 I2L BICMOS2 56.9K 1 RELIABILITY MONITOR -- ATMEL PROPRIETARY 3 High Temperature Operating Life (sorted by TECHNOLOGY) TECH QTR 48 Hours 168 Hours 500 Hours 1K Hours REJ SS REJ SS REJ SS REJ SS Device-Hours* WAF EFR PPM FITS 56K 1 LAST 4Q 0 0 100 2,850 0 0 100 629 0 0 100 629 0 0 100 629 100,000 735,608 23 14 0 0 403 90 46K 1 LAST 4Q 0 0 82 328 0 0 82 328 0 0 82 328 0 0 82 328 82,000 328,000 23 23 0 0 492 123 38.6 K 1 LAST 4Q 0 0 154 308 0 0 154 308 0 0 154 308 0 0 154 308 154,000 308,000 117 117 0 0 51 25 35K 1 LAST 4Q 0 0 1,547 7,589 0 0 576 2,409 0 0 576 2,409 0 0 531 2,272 600,108 2,742,140 26 33 0 0 59 10 34K 1 LAST 4Q 0 600 0 200 0 200 0 200 219,200 11 0 368 1 LAST 4Q 0 1,187 0 400 0 400 0 400 437,776 52 0 40 1 LAST 4Q 0 0 4,434 21,875 0 0 1,962 8,487 0 0 1,962 8,483 0 0 1,917 7,907 2,058,156 9,221,296 56 60 0 0 8 2 19K ATMEL * The Device-Hours computation includes additional read-outs not detailed in the report.

Stressing at high temperatures (150°C for plastic packages) accelerates any discharge causing the memory state to change. Failures In Time (FITS): This is the unit measure for expressing failure rates and is identical to the expression PPM/K hours. For example, three failures out of a million components tested for one thousand hours equates to 3 FITS. High Temperature Operating Life (HTOL): The purpose of this test is to accelerate thermally activated failure mechanisms through the use of high temperatures (typically between 125°C and 150°C), increased voltage, and dynamic bias conditions. Readouts at various time points are taken to determine the Early Failure Rate (EFR) and Intrinsic Failure Rate (IFR). EFR is expressed in defective parts per million (DPPM) and IFR is expressed in Failures in Time (FITS at 55°C). Highly Accelerated Stress Test (HAST): The purpose of this test is to evaluate a plastic packaged component’s ability to withstand harsh environmental conditions with extreme temperature and humidity levels. The parts are stressed to high temperature (130°C) and relative humidity (85%RH) conditions in a biased state to achieve maximum acceleration. Steam Pressure Pot (SPP): The test is used to evaluate a plastic packaged component’s ability to withstand severe conditions of pressure (15 psig), temperature (121°C), and humidity (100%RH). Temperature Cycle (TC): This test is used to measure a product’s sensitivity to thermal stresses due to differences in expansion and contraction characteristics of the die and mold compound by repeated alternating temperature dwells between high and low temperature extremes. Temperature Humidity Bias (THB): The purpose of this test (85°C/85%RH) is identical to HAST. The only difference is that HAST accelerates THB by a factor of 20:1 due to the increase in temperature during test. RELIABILITY MONITOR -- ATMEL PROPRIETARY 12
