Rev B and C
The revision letter in this section refers to the revision of the ATtiny45 device.
No known errata
•
1. EEPROM read may fail at low supply voltage / low clock frequency
•
•
•
•
1. PLL not locking
2. EEPROM read from application code does not work in Lock Bit Mode 3
3. EEPROM read may fail at low supply voltage / low clock frequency
EEPROM read may fail at low supply voltage / low clock frequency
PLL not locking
EEPROM read from application code does not work in Lock Bit Mode 3
EEPROM read may fail at low supply voltage / low clock frequency
Timer Counter 1 PWM output generation on OC1B- XOC1B does not work correctly
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.
When at frequencies below 6.0 MHz, the PLL will not lock
Problem fix / Workaround
When using the PLL, run at 6.0 MHz or higher.
When the Memory Lock Bits LB2 and LB1 are programmed to mode 3, EEPROM read does
not work from the application code.
Problem Fix/Work around
Do not set Lock Bit Protection Mode 3 when the application code needs to read from
EEPROM.
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
