Electrical Characteristics
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.

Notes: 1. “Max” means the highest value where the pin is guaranteed to be read as low

“Min” means the lowest value where the pin is guaranteed to be read as high
Although each I/O port can sink more than the test conditions (20mA at V
CC
= 5V) under steady state conditions (non-
transient), the following must be observed:
1] The sum of all IOL, for all ports, should not exceed 400mA.
2] The sum of all IOL, for ports C0 - C5, should not exceed 200mA.
3] The sum of all IOL, for ports C6, D0 - D4, should not exceed 300mA.
4] The sum of all IOL, for ports B0 - B7, D5 - D7, should not exceed 300mA.
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.
For temperature range +125°C to +150°C only. For –40°C to +125°C, refer to ATtiny167 automotive datasheet.

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
