Errata ATtiny85
Rev B and C
Rev A
The revision letter in this section refers to the revision of the ATtiny85 device.
No known errata.
•
1. EEPROM read may fail at low supply voltage / low clock frequency
EEPROM read may fail at low supply voltage / low clock frequency
Trying to read EEPROM at low clock frequencies and/or low supply voltage may result in
invalid data.
Problem Fix/Workaround
Do not use the EEPROM when clock frequency is below 1 MHz and supply voltage is below
2V. If operating frequency can not be raised above 1 MHz then supply voltage should be
more than 3V. Similarly, if supply voltage can not be raised above 2V then operating fre-
quency should be more than 2 MHz.
This feature is known to be temperature dependent but it has not been characterised.
Guidelines are given for room temperature, only.
