22. Electrical Characteristics
Note: All Characteristics contained in this data sheet are based on simulation and characterization of ATtiny87/167 AVR microcon-
trollers manufactured in a typical process technology. These values are preliminary values representing design targets, and will
be updated after characterization of actual Automotive silicon.
22.1 Absolute Maximum Ratings*
Notes: 1. Maximum current per port = ±30mA
2. Functional corruption may occur .
22.2 DC Characteristics
Operating Temperature.................................– 40°C to +125°C
*NOTICE: Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age to the device. This is a stress rating only and
functional operation of the device at these or
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.
Storage Temperature ....................................– 65°C to +150°C
Voltage on any Pin except RESET
with respect to Ground ..............................– 0.5V to Vcc+0.5V
Voltage on RESET
with respect to Ground....– 0.5V to +13.0V
Voltage on Vcc with respect to Ground..............– 0.5V to 6.0V
DC Current per I/O Pin ............................................... 40.0 mA
DC Current Vcc and GND Pins................................. 200.0 mA
Injection Current at VCC = 0V to 5V
