Although each I/O port can sink more than the test conditions (20mA at VCC = 5V) under steady state conditions (non-transient), the following must be observed: 1] The sum of all IOL, for all ports, should not exceed 400 mA. 2] The sum of all IOL, for ports C0 - C5, should not exceed 200 mA. 3] The sum of all IOL, for ports C6, D0 - D4, should not exceed 300 mA. 4] The sum of all IOL, for ports B0 - B7, D5 - D7, should not exceed 300 mA. If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater than the listed test condition. 4.

AEC-Q100 qualification relies on temperature accelerated stress testing. High temperature field usage however may result in less significant stress test acceleration. In order to prevent the risk that ATtiny45 lifetime would not satisfy the application end-of-life reliability requirements, Atmel has extended the testing, whenever applicable (High Temperature Operating Life Test, High Temperature Storage Life, Data Retention, Thermal Cycles), far beyond the AEC-Q100 requirements. Thereby, Atmel verified the ATtiny45 has a long safe lifetime period after the grade 0 qualification acceptance limits. The valid domain calculation depends on the activation energy of the potential failure mechanism that is considered. Examples are given in figure 1. Therefore any temperature mission profile which could exceed the AEC-Q100 equivalence domain shall be submitted to Atmel for a thorough reliability analysis AEC-Q100 Lifetime Equivalence 1000000 100000 Hours 10000 1000 100 10 1 0 20 40 60 80 100 120 140 160 Temperature (°C) HTOL 0,59eV HTSL 0,45eV 21 7696B–AUTO–04/08 Ordering Information ATtiny45 Speed (MHz) Power Supply Ordering Code Package(1) 16(2) 2.7 - 5.5V ATtiny45-15MT2 PC Notes: Operation Range Extended (-40°C to 150°C) 1.
