Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

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 (20 mA 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. For temperature range +125°C to +150°C only. For –40°C to +125°C, refer to ATtiny167automotive datasheet.

2. Grade 0 Qualification
The ATtiny87/ATtiny167 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 ATtiny87/ATtiny167 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 ATtiny87/ATtiny167 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. Therefore any temperature mission profile which could exceed the
AEC-Q100 equivalence domain shall be submitted to Atmel for a thorough reliability analysis
