1. "Max" means the highest value where the pin is guaranteed to be read as low 2. "Min" means the lowest value where the pin is guaranteed to be read as high 3. 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. Although each I/O port can source more than the test conditions (20mA at Vcc = 5V) under steady state conditions (nontransient), the following must be observed: 1] The sum of all IOH, for all ports, should not exceed 400 mA. 2] The sum of all IOH, for ports C0 - C5, should not exceed 200 mA. 3] The sum of all IOH, for ports C6, D0 - D4, should not exceed 300 mA. 4] The sum of all IOH, for ports B0 - B7, D5 - D7, should not exceed 300 mA.

Grade 0 Qualification
The ATMEGA88 has been developed and manufactured according to the most stringent quality assurance requirements of ISO-TS-16949 and verified during product qualification as per AEC-Q100 grade 0. 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 ATMEGA88 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 ATMEGA88 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
